Sufficient out-of-band blocking specification at the Low Noise Amplifier (LNA) input allows the radio to be used in close proximity to Global System for Mobile Communications (GSM) and Wideband Code Division Multiple Access (W-CDMA) cellular phone transmitters without being desensitised. The use of a digital Frequency Shift Keying (FSK) discriminator means that no discriminator tank is needed and its excellent performance in the presence of noise allows BlueCore3-ROM to exceed the Bluetooth requirements for co-channel and adjacent channel rejection. Low Noise Amplifier The LNA can be configured to operate in single-ended or differential mode. Single-ended mode is used for Class 1 Bluetooth operation and differential mode is used for Class 2 operation. 7.1.2 Analogue to Digital Converter The Analogue to Digital Converter (ADC) is used to implement fast Automatic Gain Control (AGC). The ADC samples the Received Signal Strength Indicator (RSSI) voltage on a slot-by-slot basis. The front-end LNA gain is changed according to the measured RSSI value, keeping the first mixer input signal within a limited range. This improves the dynamic range of the receiver, improving performance in interference limited environments. 7.2 RF Transmitter 7.2.1 IQ Modulator The transmitter features a direct IQ modulator to minimise the frequency drift during a transmit timeslot which results in a controlled modulation index. A digital baseband transmit filter provides the required spectral shaping. 7.2.2 Power Amplifier The internal Power Amplifier (PA) has a maximum output power of +6dBm allowing BlueCore3-ROM to be used in Class 2 and Class 3 radios without an external RF PA. Support for transmit power control allows a simple implementation for Class 1 with an external RF PA. 7.2.3 Auxiliary DAC An 8-bit voltage Auxiliary DAC is provided for power control of an external PA for Class 1 operation. 7.3 RF Synthesiser The radio synthesiser is fully integrated onto the die with no requirement for an external Voltage Controlled Oscillator (VCO) screening can, varactor tuning diodes or LC resonators. The synthesiser is guaranteed to lock in sufficient time across the guaranteed temperature range to meet the Bluetooth specification V1.2. 7.4 Clock Input and Generation The reference clock for the system is generated from a TCXO or crystal input between 8MHz and 40MHz. All internal reference clocks are generated using a phase locked loop, which is locked to the external reference frequency.

The dynamic allocation of memory ensures efficient use of the available Random Access Memory (RAM) and is performed by hardware MMU to minimise the overheads on the processor during data/voice transfers. 7.5.2 Burst Mode Controller 7.5.3 Physical Layer Hardware Engine DSP Dedicated logic is used to perform the following: ! Forward error correction ! Header error control ! Cyclic redundancy check ! Encryption ! Data whitening ! Access code correlation ! Audio transcoding The following voice data translations and operations are performed by firmware: ! A-law/-law/linear voice data (from host) ! A-law/-law/Continuously Variable Slope Delta (CVSD) (over the air) ! Voice interpolation for lost packets ! Rate mismatches The hardware supports all optional and mandatory features of Bluetooth v1.2 including AFH and eSCO. 7.5.4 RAM 32Kbytes of on-chip RAM is provided and is shared between the ring buffers used to hold voice/data for each active connection and the general purpose memory required by the Bluetooth stack. 7.5.5 ROM 4Mbits of metal programmable ROM is provided for system firmware implementation. 7.5.6 Flash (BlueCore3-ROM Flash Only) 4Mbits of internal Flash is available on the BlueCore3-ROM Flash, this is used for software prototyping before committing code to ROM. 7.5.7 USB This is a full speed Universal Serial Bus (USB) interface for communicating with other compatible digital devices. BlueCore3-ROM acts as a USB peripheral, responding to requests from a master host controller such as a PC.

During radio reception, the BMC stores the packet header in memory-mapped registers and the payload data in the appropriate ring buffer in RAM. This architecture minimises the intervention required by the processor during transmission and reception. Description of Functional Blocks 7.5.8 Synchronous Serial Interface This is a synchronous serial port interface (SPI) for interfacing with other digital devices. The SPI port can be used for system debugging. 7.5.9 UART This is a standard Universal Asynchronous Receiver Transmitter (UART) interface for communicating with other serial devices. 7.5.10 Audio PCM Interface 7.6 Microcontroller The microcontroller, interrupt controller and event timer run the Bluetooth software stack and control the radio and host interfaces. A 16-bit Reduced Instruction Set Computer (RISC) microcontroller is used for low power consumption and efficient use of memory. 7.6.1 Programmable I/O BlueCore3-ROM has a total of 15 (12 digital and 3 analogue) programmable I/O terminals. These are controlled by firmware running on the device.

Provides a set of approximately 50 manufacturer-specific HCI extension commands. This command set, called BCCMD (BlueCore Command), provides: ! Access to the chip's general-purpose PIO port ! The negotiated effective encryption key length on established Bluetooth links ! Access to the firmware's random number generator ! Controls to set the default and maximum transmit powers. These can help minimise interference between overlapping, fixed-location piconet ! Dynamic UART configuration ! Radio transmitter enable/disable (a simple command connects to a dedicated hardware switch that determines whether the radio can transmit) ! The firmware can read the voltage on a pair of the chip's external pins. This is normally used to build a battery monitor, using either VM or host code. ! A block of BCCMD commands provides access to the chip's "persistent store" configuration database (PS). The database sets the device's Bluetooth address, Class of Device, radio (transmit class) configuration, SCO routing, LM, USB and DFU constants, etc. ! A UART "break" condition can be used in three ways: 1. Presenting a UART break condition to the chip can force the chip to perform a hardware reboot 2. Presenting a break condition at boot time can hold the chip in a low power state, preventing normal initialisation while the condition exists 3. With H5, the firmware can be configured to send a break to the host before sending data (normally used to wake the host from a Deep Sleep state) ! A block of "radio test" or BIST commands allows direct control of the chip's radio. This aids the development of modules' radio designs, and can be used to support Bluetooth qualification. ! Virtual Machine (VM). The firmware provides the VM environment in which to run application-specific code. Although the VM is mainly used with BlueLab and "RFCOMM builds" (alternative firmware builds providing L2CAP, SDP and RFCOMM), the VM can be used with this build to perform simple tasks such as flashing LEDs via the chip's PIO port. ! Hardware low power modes: shallow sleep and deep sleep. The chip drops into modes that significantly reduce power consumption when the software goes idle. ! SCO channels are normally routed over HCI over BCSP, H5 or USB. However, up to three SCO channels can be routed over the chip's single PCM port at the same time as routing any other SCO channels over HCI. !

All software layers, including application software, run on the internal RISC microcontroller in a protected user software execution environment known as a virtual machine (VM). The user may write custom application code to run on the BlueCore VM using BlueLabTM software development kit (SDK) supplied with the BlueLab and Casira development kits, available separately from CSR. This code will then execute alongside the main BlueCore firmware. The user is able to make calls to the BlueCore firmware for various operations. The execution environment is structured so the user application does not adversely affect the main software routines, thus ensuring that the Bluetooth stack software component does not need re-qualification when the application is changed. Using the VM and the BlueLab SDK the user is able to develop applications such as a cordless headset or other profiles without the requirement of a host controller. BlueLab is supplied with example code including a full implementation of the headset profile. On successful completion of firmware development and testing using BlueCore3-ROM Flash, CSR can commit the code to a mask set for mass production of the device. A Non Recurring Engineering (NRE) charge will be required. Note: Sample applications to control PIO lines can also be written with BlueLab SDK and the VM for the HCI stack.

All software layers, including application software, run on the internal RISC microcontroller in a protected user software execution environment known as a virtual machine (VM). The user may write custom application code to run on the BlueCore VM using BlueLab Professional software development kit (SDK) supplied with the BlueLab Professional and Casira development kits, available separately from CSR. This code will then execute alongside the main BlueCore firmware. The user is able to make calls to the BlueCore firmware for various operations. The execution environment is structured so the user application does not adversely affect the main software routines, thus ensuring that the Bluetooth stack software component does not need re-qualification when the application is changed. Using the VM and the BlueLab Professional SDK the user is able to develop Bluetooth HID devices such as an optical mouse or keyboard. The user is able to customise features such as power management and connect/reconnect behaviour. The HID I/O component in the HID stack controls low latency data acquisition from external sensor hardware. With this component running in native code, it does not incur the overhead of the VM code interpreter. Supported external sensors include 5 mouse buttons, the Agilent ADNS-2030 optical sensor, quadrature scroll wheel, direct coupling to a keyboard matrix and a UART interface to custom hardware. On successful completion of firmware development and testing using BlueCore3-ROM Flash, CSR can commit the code to a mask set for mass production of the device. A non recurring engineering (NRE) charge will be required. A reference schematic for implementing a three button, optical mouse with scroll wheel is available from CSR.

BCHS is developed to work with CSR's family of BlueCore IC's. BCHS is intended for embedded products that have a host processor for running BCHS and the Bluetooth application e.g. a mobile phone or a PDA. BCHS together with the BlueCore IC with embedded Bluetooth core stack (L2CAP, RFCOMM and SDP) is a complete Bluetooth system solution from RF to profiles. BCHS includes most of the Bluetooth intelligence and gives the user a simple API. This makes it possible to develop a Bluetooth product without in-depth Bluetooth knowledge. ! Example Drivers (BCSP and proxies) ! Bluetooth Profile Managers ! Example Applications The profiles are qualified which makes the qualification of the final product very easy. BCHS is delivered with source code (ANSI C). With BCHS also come example applications in ANSI C, which makes the process of writing the application easier. 8.6 Additional Software for Other Embedded Applications When the upper layers of the Bluetooth protocol stack are run as firmware on BlueCore3-ROM, a UART software driver is supplied that presents the L2CAP, RFCOMM and Service Discovery (SDP) APIs to higher Bluetooth stack layers running on the host. The code is provided as `C' source or object code. 8.7 CSR Development Systems CSR's BlueLab and Casira development kits are available to allow the evaluation of the BlueCore3 hardware and software, and as toolkits for developing on-chip and host software.

This reference may be either an external clock or from a crystal connected between XTAL_IN and XTAL_OUT. The crystal mode is described in Section 9.4. 9.3.1 External Mode The external clock signal should meet the specifications in Table 9.5: Min Typ Max Frequency 7.5MHz 16MHz 40MHz Duty cycle 20:80 50:50 80:20 - - 15ps rms 400mV pk-pk - VDD_ANA(2)(3) (1) Edge Jitter (At Zero Crossing) Signal Level Table 9.4: External Clock Specifications Notes: (1) The frequency should be an integer multiple of 250kHz except for the CDMA/3G frequencies (2) VDD_ANA is 1.8V nominal (3) If the external clock is driven through a DC blocking capacitor then maximum allowable amplitude is reduced from VDD_ANA to 800mV pk-pk 9.3.2 XTAL_IN Impedance in External Mode The impedance of the XTAL_IN will not change significantly between operating modes, typically 10fF. When transitioning from deep sleep to an active state a spike of up to 1pC may be measured. For this reason it is recommended that a buffered clock input be used. BC313143A-ds-001Pn Production Information (c) Cambridge Silicon Radio Ltd. 2005 This material is subject to CSR's non-disclosure agreement Page 56 of 108 _aiEceEPJolj Product Data Sheet BlueCore3-ROM can be configured to accept an external reference clock (from another device, such as TCXO) at XTAL_IN by connecting XTAL_OUT to ground. The external clock can either be a digital level square wave or sinusoidal and this may be directly coupled to XTAL_IN without the need for additional components. If the peaks of the reference clock are below VSS_ANA or above VDD_ANA, it must be driven through a DC blocking capacitor (~33pF) connected to XTAL_IN. A digital level reference clock gives superior noise immunity as the high slew rate clock edges have lower voltage to phase conversion. Device Terminal Descriptions 9.3.3 Clock Timing Accuracy As Figure 9.12 indicates, the 250ppm timing accuracy on the external clock is required 7ms after the assertion of the system clock request line. This is to guarantee that the firmware can maintain timing accuracy in accordance with the Bluetooth v1.2 specification. Radio activity may occur after 11ms, therefore at this point, the timing accuracy of the external clock source must be within 20ppm. 9.3.4 Clock Start-Up Delay BlueCore3-ROM hardware incorporates an automatic 5ms delay after the assertion of the system clock request signal before running firmware. This is suitable for most applications using an external clock source. However, there may be scenarios where the clock cannot be guaranteed to either exist or be stable after this period. Under these conditions, BlueCore3-ROM firmware provides a software function which will extend the system clock request signal by a period stored in PSKEY_CLOCK_STARTUP_DELAY. This value is set in milliseconds from 5-31ms. This PS Key allows the designer to optimise a system where clock latencies may be longer than 5ms while still keeping the current consumption of BlueCore3-ROM as low as possible. BlueCore3-ROM will consume about 2mA of current for the duration of PSKEY_CLOCK_STARTUP_DELAY before activating the firmware.

This is accomplished by setting the PS Key PSKEY_ANA_FREQ (0x1fe) for all frequencies with an integer multiple of 250KHz. The input frequency default setting in BlueCore3-ROM is 26MHz. The following CDMA/3G TCXO frequencies are also catered for: 7.68, 14.4, 15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8 and 38.4MHz. This is accomplished by also changing PSKEY PLLX_FREQ_REF (0xabc).

This reference may be either an external clock or from a crystal connected between XTAL_IN and XTAL_OUT. The external reference clock mode is described in Section 9.3. 9.4.1 XTAL Mode BlueCore3-ROM contains a crystal driver circuit. This operates with an external crystal and capacitors to form a Pierce oscillator. Cint Ctrim XTAL_OUT Ctrim XTAL_IN BlueCore3-ROM - Ct2 Ct1 Figure 9.14: Crystal Driver Circuit Figure 9.15 shows an electrical equivalent circuit for a crystal. The crystal appears inductive near its resonant frequency. It forms a resonant circuit with its load capacitors. Cm Lm Rm Co Figure 9.15: Crystal Equivalent Circuit The resonant frequency may be trimmed with the crystal load capacitance. BlueCore3-ROM contains variable internal capacitors to provide a fine trim. The BlueCore3-ROM driver circuit is a transconductance amplifier. A voltage at XTAL_IN generates a current at XTAL_OUT. The value of transconductance is variable and may be set for optimum performance.

This is the total capacitance across the crystal viewed from its terminals. BlueCore3-ROM provides some of this load with the capacitors Ctrim and Cint. The remainder should be from the external capacitors labelled Ct1 and Ct2. Ct1 should be three times the value of Ct2 for best noise performance. This maximises the signal swing, hence slew rate at XTAL_IN, to which all on chip clocks are referred. Crystal load capacitance, Cl is calculated with the following equation: Cl = Cint + C trim C C + t1 t 2 2 C t1 + C t 2 Equation 9.1: Load Capacitance Ctrim = 3.4pF nominal (Mid range setting) Cint = 1.5pF Note: Cint does not include the crystal internal self capacitance, it is the driver self capacitance 9.4.3 Frequency Trim BlueCore3-ROM enables frequency adjustments to be made. This feature is typically used to remove initial tolerance frequency errors associated with the crystal. Frequency trim is achieved by adjusting the crystal load capacitance with on chip trim capacitors, Ctrim. The value of Ctrim is set by a 6-bit word in the Persistent Store Key PSKEY_ANA_FTRIM (0x1f6). Its value is calculated thus: Ctrim = 110 fF x PSKEY_ANA_FTRIM Equation 9.2: Trim Capacitance There are two Ctrim capacitors, which are both connected to ground. When viewed from the crystal terminals, they appear in series so each least significant bit (LSB) increment of frequency trim presents a load across the crystal of 55fF. The frequency trim is described by Equation 9.3: (Fx ) = pullability x 55 x 10 -3 (ppm / LSB ) Fx Equation 9.3: Frequency Trim Where Fx is the crystal frequency and pullability is a crystal parameter with units of ppm/pF. Total trim range is 63 times the value above. If not specified, the pullability of a crystal may be calculated from its motional capacitance with Equation 9.4: Cm (Fx ) = Fx (C) 4(Cl + C0 )2 Equation 9.4: Pullability Where: C0 = Crystal self capacitance (shunt capacitance) Cm = Crystal motional capacitance (series branch capacitance in crystal model). See Figure 9.15. Note: It is a Bluetooth requirement that the frequency is always within 20ppm. The trim range should be sufficient to pull the crystal within 5ppm of the exact frequency. This leaves a margin of 15ppm for frequency drift with ageing and temperature. A crystal with an ageing and temperature drift specification of better than 15ppm is required.

The transconductance amplifier in BlueCore3-ROM uses the voltage at its input, XTAL_IN, to generate a current at its output, XTAL_OUT. Therefore, the circuit will oscillate if the transconductance, transimpedance product is greater than unity. For sufficient oscillation amplitude, the product should be greater than 3. The transconductance required for oscillation is defined by the following relationship: gm > 3(Ct1 +Ctrim )(Ct 2 + Ctrim ) (2Fx ) Rm ((C0 + Cint )(Ct1 + Ct 2 + 2Ctrim ) + (Ct1 + Ctrim )(Ct 2 + Ctrim ))2 2 Equation 9.5: Transconductance Required for Oscillation Notes: More drive strength is required for higher frequency crystals, higher loss crystals (larger Rm) or higher capacitance loading. Optimum drive level is attained when the level at XTAL_IN is approximately 1V pk-pk. The drive level is determined by the crystal driver transconductance, by setting the Persistent Store KEY_XTAL_LVL (0x241). 9.4.5 Negative Resistance Model An alternative representation of the crystal and its load capacitors is a frequency dependent resistive element. The driver amplifier may be considered as a circuit that provides negative resistance. For oscillation, the value of the negative resistance must be greater than that of the crystal circuit equivalent resistance. Although the BlueCore3-ROM crystal driver circuit is based on a transimpedance amplifier, an equivalent negative resistance may be calculated for it with the following formula in Equation 9.6: Rneg > 3(Ct1 +Ctrim )(Ct 2 + Ctrim ) gm (2Fx ) (C0 + Cint )((Ct1 + Ct 2 + 2Ctrim ) + (Ct1 + Ctrim )(Ct 2 + Ctrim ))2 2 Equation 9.6: Equivalent Negative Resistance This formula shows the negative resistance of the BlueCore3-ROM driver as a function of its drive strength. The value of the driver negative resistance may be easily measured by placing an additional resistance in series with the crystal. The maximum value of this resistor (oscillation occurs) is the equivalent negative resistance of the oscillator.

BlueCore3-ROM UART_TX UART_RX UART_CTS Figure 9.19: Universal Asynchronous Receiver Four signals are used to implement the UART function, as shown in Figure 9.19. When BlueCore3-ROM is connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. All UART connections are implemented using CMOS technology and have signalling levels of 0V and VDD_PADS. UART configuration parameters, such as Baud rate and packet format, are set using BlueCore3-ROM software. Notes: In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial port adapter card is required for the PC.

A Break is identified by a continuous logic low (0V) on the UART_RX terminal, as shown in Figure 9.20. If tBRK is longer than the value, defined by the PS Key PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a host to initialise the system to a known state. Also, BlueCore3-ROM can emit a Break character that may be used to wake the Host. t BRK UART RX Figure 9.20: Break Signal Note: Table 9.8 shows a list of commonly used Baud rates and their associated values for the Persistent Store Key PSKEY_UART_BAUD_RATE (0x204).

This will allow the user to daisy chain devices onto the physical UART bus. The constraint on this method is that any devices connected to this bus must tri-state when BlueCore3-ROM reset is de-asserted and the firmware begins to run. 9.5.3 UART Bypass Mode Alternatively, for devices that do not tri-state the UART bus, the UART bypass mode on BlueCore3-ROM can be used. The default state of BlueCore3-ROM after reset is de-asserted is for the host UART bus to be connected to the BlueCore3-ROM UART, thereby allowing communication to BlueCore3-ROM via the UART. In order to apply the UART bypass mode, a BCCMD command will be issued to BlueCore3-ROM upon this, it will switch the bypass to PIO[7:4] as shown in Figure 9.21. Once the bypass mode has been invoked, BlueCore3-ROM will enter the deep sleep state indefinitely. In order to re-establish communication with BlueCore3-ROM, the chip must be reset so that the default configuration takes affect. It is important for the host to ensure a clean Bluetooth disconnection of any active links before the bypass mode is invoked. Therefore it is not possible to have active Bluetooth links while operating the bypass mode. 9.5.4 Current Consumption in UART Bypass Mode The current consumption for a device in UART Bypass Mode is equal to the values quoted for a device in standby mode.

No external USB transceiver is required. The device operates as a USB peripheral, responding to requests from a master host controller such as a PC. Both the OHCI and the UHCI standards are supported. The set of USB endpoints implemented can behave as specified in the USB section of the Bluetooth specification v1.2 or alternatively can appear as a set of endpoints appropriate to USB audio devices such as speakers. As USB is a Master/Slave oriented system (in common with other USB peripherals), BlueCore3-ROM only supports USB Slave operation. 9.6.1 USB Data Connections 9.6.2 USB Pull-Up Resistor BlueCore3-ROM features an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when BlueCore3-ROM is ready to enumerate. It signals to the PC that it is a full speed (12Mbit/s) USB device. The USB internal pull-up is implemented as a current source, and is compliant with Section 7.1.5 of the USB specification v1.2. The internal pull-up pulls USB_DP high to at least 2.8V when loaded with a 15k 5% pull-down resistor (in the hub/host) when VDD_PADS=3.1V. This presents a Thevenin resistance to the host of at least 900. Alternatively, an external 1.5k pull-up resistor can be placed between a PIO line and D+ on the USB cable. The firmware must be alerted to which mode is used by setting PS Key PSKEY_USB_PIO_PULLUP appropriately. The default setting uses the internal pull-up resistor. 9.6.3 Power Supply The USB specification dictates that the minimum output high voltage for USB data lines is 2.8V. To safely meet the USB specification, the voltage on the VDD_USB supply terminals must be an absolute minimum of 3.1V. CSR recommends 3.3V for optimal USB signal quality. BC313143A-ds-001Pn Production Information (c) Cambridge Silicon Radio Ltd. 2005 This material is subject to CSR's non-disclosure agreement Page 68 of 108 _aiEceEPJolj Product Data Sheet The USB data lines emerge as pins USB_DP and USB_DN. These terminals are connected to the internal USB I/O buffers of the BlueCore3-ROM and therefore have a low output impedance. To match the connection to the characteristic impedance of the USB cable, resistors must be placed in series with USB_DP / USB_DN and the cable. Device Terminal Descriptions 9.6.4 Self Powered Mode In self powered mode, the circuit is powered from its own power supply and not from the VBUS (5V) line of the USB cable. It draws only a small leakage current (below 0.5mA) from VBUS on the USB cable. This is the easier mode for which to design for, as the design is not limited by the power that can be drawn from the USB hub or root port. However, it requires that VBUS be connected to BlueCore3-ROM via a resistor network (Rvb1 and Rvb2), so BlueCore3-ROM can detect when VBUS is powered up. BlueCore3-ROM will not pull USB_DP high when VBUS is off. Self powered USB designs (powered from a battery or PSU) must ensure that a PIO line is allocated for USB pull-up purposes. A 1.5K 5% pull-up resistor between USB_DP and the selected PIO line should be fitted to the design. Failure to fit this resistor may result in the design failing to be USB compliant in self powered mode. The internal pull-up in BlueCore is only suitable for bus powered USB devices i.e. dongles. PIO 1.5K 5% Rs D+ USB_DP Rs USB_DN DRvb1 VBUS USB_ON Rvb2 GND Figure 9.22: USB Connections for Self Powered Mode The terminal marked USB_ON can be any free PIO pin.

BlueCore3-ROM negotiates with the PC during the USB enumeration stage about how much current it is allowed to consume. For Class 2 Bluetooth applications, CSR recommends that the regulator used to derive 3.3V from VBUS is rated at 100mA average current and should be able to handle peaks of 120mA without foldback or limiting. In bus powered mode, BlueCore3-ROM requests 100mA during enumeration. When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging reservoir and supply decoupling capacitors) is limited by the USB specification (see USB specification v1.1, Section 7.2.4.1). Some applications may require soft start circuitry to limit inrush current if more than 10F is present between VBUS and GND. The 5V VBUS line emerging from a PC is often electrically noisy. As well as regulation down to 3.3V and 1.8V, applications should include careful filtering of the 5V line to attenuate noise that is above the voltage regulator bandwidth. Excessive noise on the 1.8V supply to the analogue supply pins of BlueCore3-ROM will result in reduced receive sensitivity and a distorted RF transmit signal.

This is accomplished by setting the PS Key PSKEY_USB_MAX_POWER (0x2c6). This is higher than for a Class 2 application due to the extra current drawn by the Transmit RF PA. Device Terminal Descriptions 9.6.6 Suspend Current All USB devices must permit the USB controller to place them in a USB Suspend mode. While in USB Suspend, bus powered devices must not draw more than 0.5mA from USB VBUS (self powered devices may draw more than 0.5mA from their own supply). This current draw requirement prevents operation of the radio by bus powered devices during USB Suspend. The voltage regulator circuit itself should draw only a small quiescent current (typically less than 100A) to ensure adherence to the suspend current requirement of the USB specification. This is not normally a problem with modern regulators. Ensure that external LEDs and/or amplifiers can be turned off by BlueCore3-ROM. The entire circuit must be able to enter the suspend mode. (For more details on USB Suspend, see separate CSR documentation). Detach and Wake_Up Signalling BlueCore3-ROM can provide out-of-band signalling to a host controller by using the control lines called `USB_DETACH' and `USB_WAKE_UP'. These are outside the USB specification (no wires exist for them inside the USB cable), but can be useful when embedding BlueCore3-ROM into a circuit where no external USB is visible to the user. Both control lines are shared with PIO pins and can be assigned to any PIO pin by setting the PS Keys PSKEY_USB_PIO_DETACH and PSKEY_USB_PIO_WAKEUP to the selected PIO number. USB_DETACH is an input which, when asserted high, causes BlueCore3-ROM to put USB_DN and USB_DP in a high impedance state and turned off the pull-up resistor on DP. This detaches the device from the bus and is logically equivalent to unplugging the device. When USB_DETACH is taken low, BlueCore3-ROM will connect back to USB and await enumeration by the USB host. USB_WAKE_UP is an active high output (used only when USB_DETACH is active) to wake up the host and allow USB communication to recommence. It replaces the function of the software USB WAKE_UP message (which runs over the USB cable), and cannot be sent while BlueCore3-ROM is effectively disconnected from the bus. 10ms max 10ms max USB_DETACH 10ms max No max USB_WAKE_UP Port_Impedance USB_DP USB_DN USB_PULL_UP Disconnected Figure 9.24: USB_DETACH and USB_WAKE_UP Signal 9.6.8 USB Driver A USB Bluetooth device driver is required to provide a software interface between BlueCore3-ROM and Bluetooth software running on the host computer.

The specification contains valuable information on aspects such as PCB track impedance, supply inrush current and product labelling. Although BlueCore3-ROM meets the USB specification, CSR cannot guarantee that an application circuit designed around the chip is USB compliant. The choice of application circuit, component choice and PCB layout all affect USB signal quality and electrical characteristics. The information in this document is intended as a guide and should be read in association with the USB specification, with particular attention being given to Chapter 7. Independent USB qualification must be sought before an application is deemed USB compliant and can bear the USB logo. Such qualification can be obtained from a USB plugfest or from an independent USB test house. 9.6.10 USB 2.0 Compatibility BlueCore3-ROM is compatible with USB v2.0 host controllers; under these circumstances the two ends agree the mutually acceptable rate of 12Mbits/s according to the USB v2.0 specification. 9.7 Serial Peripheral Interface BlueCore3-ROM uses 16-bit data and 16-bit address serial peripheral interface, where transactions may occur when the internal processor is running or is stopped. This section details the considerations required when interfacing to BlueCore3-ROM via the four dedicated serial peripheral interface terminals. Data may be written or read one word at a time or the auto increment feature may be used to access blocks. 9.7.1 Instruction Cycle The BlueCore3-ROM is the slave and receives commands on SPI_MOSI and outputs data on SPI_MISO. The instruction cycle for a SPI transaction is shown in Table 9.10. 1 Reset the SPI interface Hold SPI_CSB high for two SPI_CLK cycles 2 Write the command word Take SPI_CSB low and clock in the 8 bit command 3 Write the address Clock in the 16-bit address word 4 Write or read data words Clock in or out 16-bit data word(s) 5 Termination Take SPI_CSB high Table 9.10: Instruction Cycle for an SPI Transaction With the exception of reset, SPI_CSB must be held low during the transaction. Data on SPI_MOSI is clocked into the BlueCore3-ROM on the rising edge of the clock line SPI_CLK. When reading, BlueCore3-ROM will reply to the master on SPI_MISO with the data changing on the falling edge of the SPI_CLK. The master provides the clock on SPI_CLK. The transaction is teminated by taking SPI_CSB high. Sending a command word and the address of a register for every time it is to be read or written is a significant overhead, especially when large amounts of data are to be transferred. To overcome this BlueCore3-ROM offers increased data transfer efficiency via an auto increment operation. To invoke auto increment, SPI_CSB is kept low, which auto increments the address, while providing an extra 16 clock cycles for each extra word to be written or read.

Device Terminal Descriptions 9.7.2 Writing to BlueCore3-ROM To write to BlueCore3-ROM, the 8-bit write command (00000010) is sent first (C[7:0]) followed by a 16-bit address (A[15:0]). The next 16-bits (D[15:0]) clocked in on SPI_MOSI are written to the location set by the address (A). Thereafter for each subsequent 16-bits clocked in, the address (A) is incremented and the data written to consecutive locations until the transaction terminates when SPI_CSB is taken high.

An 8-bit read command (00000011) is sent first (C[7:0]), followed by the address of the location to be read (A[15:0]). BlueCore3-ROM then outputs on SPI_MISO a check word during T[15:0] followed by the 16-bit contents of the addressed location during bits D[15:0]. The check word is composed of {command, address [15:8]}. The check word may be used to confirm a read operation to a memory location. This overcomes the problems encountered with typical serial peripheral interface slaves, whereby it is impossible to determine whether the data returned by a read operation is valid data or the result of the slave device not responding. If SPI_CSB is kept low, data from consecutive locations is read out on SPI_MISO for each subsequent 16 clocks, until the transaction terminates when SPI_CSB is taken high.

When BlueCore3-ROM is deselected (SPI_CSB = 1), the SPI_MISO line does not float, instead, BlueCore3-ROM outputs 0 if the processor is running or 1 if it is stopped.

Through its PCM interface, BlueCore3-ROM has hardware support for continual transmission and reception of PCM data, thus reducing processor overhead for wireless headset applications. BlueCore3-ROM offers a bi directional digital audio interface that routes directly into the baseband layer of the on chip firmware. It does not pass through the HCI protocol layer. Hardware on BlueCore3-ROM allows the data to be sent to and received from a SCO connection. (1) Up to three SCO connections can be supported by the PCM interface at any one time . It supports 13 or 16-bit linear, 8-bit -law or A-law companded sample formats at 8ksamples/s and can receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM configuration options are enabled by setting the PS Key PS KEY_PCM_CONFIG (0x1b3). BlueCore3-ROM interfaces directly to PCM audio devices including the following: ! Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices ! OKI MSM7705 four channel A-law and -law CODEC ! Motorola MC145481 8-bit A-law and -law CODEC !

In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When BlueCore3-ROM is configured as PCM Master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8bits long. When BlueCore3-ROM is configured as PCM Slave, PCM_SYNC may be from two consecutive falling edges of PCM_CLK to half the PCM_SYNC rate, i.e. 62.5s long.

The first is generating these signals by Direct Digital Synthesis (DDS) from BlueCore3-ROM internal 4MHz clock (which is used in BlueCore3-ROM). Using this mode limits PCM_CLK to 128, 256 or 512kHz and PCM_SYNC to 8kHz. The second is generating PCM_CLK and PCM_SYNC by DDS from an internal 48MHz clock which allows a greater range of frequencies to be generated with low jitter but consumes more power. This second method is selected by setting bit `48M_PCM_CLK_GEN_EN' in PSKEY_PCM_CONFIG32. Note: The bit `SLAVE_MODE_EN' should also be set. When in this mode and with long frame sync, the length of PCM_SYNC can be either 8 or 16 cycles of PCM_CLK, determined by `LONG_LENGTH_SYNC_EN' in PSKEY_PCM_CONFIG32. The Equation 9.8 describes PCM_CLK frequency when being generated using the internal 48MHz clock: f = CNT _ RATE x 24MHz CNT _ LIMIT Equation 9.8: PCM_CLK Frequency When Being Generated Using the Internal 48MHz clock The frequency of PCM_SYNC relative to PCM_CLK can be set using following equation: f= PCM _ CLK SYNC _ LIMIT x 8 Equation 9.9: PCM_SYNC Frequency Relative to PCM_CLK CNT_RATE, CNT_LIMIT and SYNC_LIMIT are set using PSKEY_PCM_LOW_JITTER_CONFIG. As an example, to generate PCM_CLK at 512kHz with PCM_SYNC at 8kHz, set PSKEY_PCM_LOW_JITTER_CONFIG to 0x08080177.

The following tables detail these PS Keys. PSKEY_PCM_CONFIG32. The default for this key is 0x00800000 i.e. first slot following sync is active, 13-bit linear voice format, long frame sync and interface master generating 256kHz PCM_CLK from 4MHz internal clock with no tristating of PCM_OUT. PSKEY_PCM_LOW_JITTER_CONFIG is described in Table 9.14. Name Bit Position Description 0 Set to 0. SLAVE_MODE_EN 1 0 selects Master mode with internal generation of PCM_CLK and PCM_SYNC. 1 selects Slave mode requiring externally generated PCM_CLK and PCM_SYNC. This should be set to 1 if 48M_PCM_CLK_GEN_EN (bit 11) is set. SHORT_SYNC_EN 2 0 selects long frame sync (rising edge indicates start of frame), 1 selects short frame sync (falling edge indicates start of frame). - 3 Set to 0. SIGN_EXTEND_EN 4 0 selects padding of 8 or 13-bit voice sample into a 16-bit slot by inserting extra LSBs, 1 selects sign extension. When padding is selected with 13-bit voice sample, the 3 padding bits are the audio gain setting; with 8-bit samples the 8 padding bits are zeroes. LSB_FIRST_EN 5 0 transmits and receives voice samples MSB first, 1 uses LSB first. TX_TRISTATE_EN 6 0 drives PCM_OUT continuously, 1 tri-states PCM_OUT immediately after the falling edge of PCM_CLK in the last bit of an active slot, assuming the next slot is not active. TX_TRISTATE_RISING_EDGE_EN 7 0 tristates PCM_OUT immediately after the falling edge of PCM_CLK in the last bit of an active slot, assuming the next slot is also not active. 1 tristates PCM_OUT after the rising edge of PCM_CLK. SYNC_SUPPRESS_EN 8 0 enables PCM_SYNC output when master, 1 suppresses PCM_SYNC whilst keeping PCM_CLK running. Some CODECS utilise this to enter a low power state. GCI_MODE_EN 9 1 enables GCI mode. MUTE_EN 10 1 forces PCM_OUT to 0. 48M_PCM_CLK_GEN_EN 11 0 sets PCM_CLK and PCM_SYNC generation via DDS from internal 4 MHz clock, as for BlueCore3-ROM. 1 sets PCM_CLK and PCM_SYNC generation via DDS from internal 48 MHz clock. LONG_LENGTH_SYNC_EN 12 0 sets PCM_SYNC length to 8 PCM_CLK cycles and 1 sets length to 16 PCM_CLK cycles. Only applies for long frame sync and with 48M_PCM_CLK_GEN_EN set to 1. - [20:16] Set to 0b00000.

PIO[11:8] and PIO[3:0] are powered from VDD_PIO. PIO[7:4] are powered from VDD_PADS. AIO [2:0] are powered from VDD_MEM. PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO lines are configured as inputs with weak pull-downs at reset. PIO[0] and PIO[1] are normally dedicated to RXEN and TXEN respectively, but they are available for general use. BlueCore3-ROM has three general purpose analogue interface pins, AIO[0], AIO[1] and AIO[2]. These are used to access internal circuitry and control signals. One pin is allocated to decoupling for the on-chip bandgap reference voltage, the other two may be configured to provide additional functionality. Auxiliary functions available via these pins include an 8-bit ADC and an 8-bit DAC. Typically the ADC is used for battery voltage measurement. Signals selectable at these pins include the bandgap reference voltage and a variety of clock signals; 48, 24, 16, 8MHz and the XTAL clock frequency. When used with analogue signals the voltage range is constrained by the analogue supply voltage (1.8V). When configured to drive out digital level signals (clocks) generated from within the analogue part of the device, the output voltage level is determined by VDD_MEM (1.8V). BC313143A-ds-001Pn Production Information (c) Cambridge Silicon Radio Ltd. 2005 This material is subject to CSR's non-disclosure agreement Page 85 of 108 _aiEceEPJolj Product Data Sheet Any of the PIO lines can be configured as interrupt request lines or as wake-up lines from sleep modes. PIO[6] or PIO [2] can be configured as a request line for an external clock source. This is useful when the clock to BlueCore3-ROM is provided from a system application specific integrated circuit (ASIC). Using PSKEY_CLOCK_REQUEST_ENABLE, (0x246) this terminal can be configured to be low when BlueCore3-ROM is in deep sleep and high when a clock is required. The clock must be supplied within 4ms of the rising edge of PIO[6] or PIO[2] to avoid losing timing accuracy in certain Bluetooth operating modes. Device Terminal Descriptions I2C Interface 9.9 PIO[8:6] can be used to form a Master I2C interface. The interface is formed using software to drive these lines. Therefore it is suited only to relatively slow functions such as driving a dot matrix liquid crystal display (LCD), keyboard scanner or EEPROM. Notes: PIO lines need to be pulled-up through 2.2k resistors. PIO[7:6] dual functions, UART bypass and EEPROM support, therefore devices using an EEPROM cannot support UART bypass mode +1.8V 10nF 2.2K 2.2K 2.2K U2 8 7 PIO[8] 6 PIO[6] 5 PIO[7] VCC A0 WP A1 SCL A2 SDA GND 1 2 3 4 Serial EEPROM (AT24C16A) Figure 9.38: Example EEPROM Connection 9.10 TCXO Enable OR Function An OR function exists for clock enable signals from a host controller and BlueCore3-ROM where either device can turn on the clock without having to wake up the other device. PIO[3] can be used as the Host clock enable input and PIO[2] can be used as the OR output with the TCXO enable signal from BlueCore3-ROM.

Therefore, the developer must ensure that the circuitry connected to this pin is pulled via a 470k resistor to the appropriate power rail. This ensures that the TCXO is oscillating at start up.

This provides information on the type of devices which are currently supported. Device Terminal Descriptions 9.11 RESET and RESETB BlueCore3-ROM may be reset from several sources: RESET or RESETB pins, power on reset, a UART break character or via a software configured watchdog timer. The RESET pin is an active high reset and is internally filtered using the internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESET being active. CSR recommends that RESET is applied for a period greater than 5ms. The RESETB pin is the active low version of RESET and is `ORed' on-chip with the active high RESET with either causing the reset function. The power on reset occurs when the VDD_CORE supply falls below typically 1.5V and is released when VDD_CORE rises above typically 1.6V. Following a reset, BlueCore3-ROM assumes the maximum XTAL_IN frequency which ensures that the internal clocks run at a safe (low) frequency until BlueCore-ROM is configured for the actual XTAL_IN frequency. If no clock is present at XTAL_IN, the oscillator in BlueCore3-ROM free runs, again at a safe frequency.

It is advised that a smoothing circuit using a 2.2F low ESR capacitor and 2.2 resistor be placed on the output VDD_ANA. VREG_EN is provided so that the regulator can be turned off when the line is pulled low. The regulator is switched into a low power mode when the device is sent into deep sleep mode. When the on-chip regulator is not required VDD_ANA is a 1.8V input and VREG_IN must be either open circuit or tied to VDD_ANA. If BlueCore3-ROM Flash is being used as a development part to replicate BlueCore3-ROM functionality then VREG_EN must be pulled high externally to replicate the ROM devices functionality. If VREG_EN is not being used then connect pin VREG_EN to VREG_IN. 9.12.2 Sequencing It is recommended that VDD_CORE, VDD_RADIO, VDD_VCO and VDD_MEM are powered at the same time. The order of powering supplies for VDD_CORE, VDD_PIO, VDD_PADS and VDD_USB is not important. However, if VDD_CORE is not present all inputs have a weak pull-down irrespective of the reset state. 9.12.3 Sensitivity to Disturbances It is recommended that if you are supplying BlueCore3-ROM from an external voltage source that VDD_VCO, VDD_ANA and VDD_RADIO should have less than 10mV rms noise levels between 0 to 10MHz. Single tone frequencies are also to be avoided. A simple RC filter is recommended for VDD_CORE as this reduces transients put back onto the power supply rails. The transient response of the regulator is also important as at the start of a packet, power consumption will jump to the levels defined in average current consumption section. It is essential that the power rail recovers quickly, so the regulator should have a response time of 20s or less.

With solder mask defined pads, the overlap of the solder mask on the land creates a step in the solder at the land interface, which can cause stress concentration and act as a point for crack initiation ! Ideally, via-in-pad technology should be employed to achieve truly NSMD lands. Where this is not possible, a maximum of one trace connected to each land is preferred and this trace should be as thin as possible - taking into consideration its current carrying and the radio frequency (RF) requirements ! 35 micron thick (1 oz.) copper lands are recommended rather than 17 micron thick (1/2 oz.), because this results in a greater standoff which has been proven to provide greater reliability during thermal cycling ! Land diameter should be 260 microns +/-10 microns to achieve optimum reliability ! Solder paste is preferred to flux during the assembly process, as this adds to the final volume of solder in the joint, increasing its reliability ! Where a nickel gold plating finish is used, the gold thickness should be kept below 0.5 microns in order to prevent brittle gold/tin intermetallics forming in the solder BC313143A-ds-001Pn Production Information (c) Cambridge Silicon Radio Ltd. 2005 This material is subject to CSR's non-disclosure agreement Page 91 of 108 _aiEceEPJolj Product Data Sheet !

The data here is given only for guidance on solder re-flow. There are four zones: Preheat Zone: This zone raises the temperature at a controlled rate, typically 1-2.5C/s. 2. Equilibrium Zone: This zone brings the board to a uniform temperature and also activates the flux. The duration in this zone (typically 2-3 minutes) will need to be adjusted to optimise the out gassing of the flux. 3. Reflow Zone: The peak temperature should be high enough to achieve good wetting but not so high as to cause component discoloration or damage. Excessive soldering time can lead to intermetallic growth which can result in a brittle joint. 4. Cooling Zone: The cooling rate should be fast, to keep the solder grains small which will give a longer lasting joint. Typical rates will be 2-5C/s. 13.1 Example Solder Re-flow Profile for Devices with Lead-Free Solder Balls Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5% Lead-Free Reflow Solder Profile 2 300 250 Temperature (C) 200 150 100 50 0 0 50 100 150 200 250 300 350 400 450 500 Time (s) Figure 13.1: Typical Lead-Free Re-flow Solder Profile Key features of the profile: !
