CSR1010 QFN
Data Sheet
1.4 PCB Design and Assembly Considerations
This section lists recommendations to achieve maximum board-level reliability of the 5 x 5 x 0.6mm QFN 32-lead
package:
■
NSMD lands (lands smaller than the solder mask aperture) are preferred, because of the greater accuracy
of the metal definition process compared to the solder mask process. 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.
■
CSR recommends that the PCB land pattern is in accordance with IPC standard IPC-7351.
■
Solder paste must be used during the assembly process.
1.5 Typical Solder Reflow Profile

CSR1010 QFN
Data Sheet
2 Bluetooth Modem
2.1 RF Ports
CSR1010 QFN contains an integrated balun which provides a single-ended RF TX / RX port pin. No matching
components are needed as the receive mode impedance is 50Ω and the transmitter has been optimised to deliver
power in to a 50Ω load.
2.2 RF Receiver
The receiver features a near-zero IF architecture that allows the channel filters to be integrated onto the die. Sufficient
out-of-band blocking specification at the LNA input allows the receiver to be used in close proximity to GSM and
W‑CDMA cellular phone transmitters without being significantly desensitised.
An ADC digitises the IF received signal.
2.2.1 Low Noise Amplifier
The LNA operates in differential mode and takes its input from the balanced port of the integrated balun.
2.2.2 RSSI Analogue to Digital Converter
The ADC samples the RSSI voltage on a packet-by-packet basis and implements a fast AGC. 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.
2.3 RF Transmitter
2.3.1 IQ Modulator
The transmitter features a direct IQ modulator to minimise frequency drift during a transmit packet, which results in
a controlled modulation index. Digital baseband transmit circuitry provides the required spectral shaping.
2.3.2 Power Amplifier
The internal PA has a maximum 7.5dBm output power without needing an external RF PA.
2.4 Bluetooth Radio Synthesiser
The Bluetooth radio synthesiser is fully integrated onto the die with no requirement for an external VCO screening
can, varactor tuning diodes, LC resonators or loop filter. The synthesiser is guaranteed to lock in sufficient time
across the guaranteed temperature range to meet the Bluetooth v4.0 specification.
2.5 Baseband
2.5.1 Physical Layer Hardware Engine
Dedicated logic performs:
■
Cyclic redundancy check
■
Encryption
■
Data whitening
■
Access code correlation
The hardware supports all optional and mandatory features of Bluetooth v4.0 specification.

3Clock Generation
The Bluetooth reference clock for the system is generated from an external 16MHz clock source, see Figure 3.1. All
the CSR1010 QFN internal digital clocks are generated using a phase locked loop, which is locked to the frequency
of either the external reference clock source or a sleep clock frequency of 32.768kHz, see Figure 3.1.

5 Serial Interfaces
5.1 Application Interface
5.1.1 UART Interface
The CSR1010 QFN UART interface provides a simple mechanism for communicating with other serial devices using
the RS232 protocol.
2 signals implement the UART function, UART_TX and UART_RX. When CSR1010 QFN is connected to another
digital device, UART_RX and UART_TX transfer data between the 2 devices.
UART configuration parameters, e.g. baud rate and data format, are set using CSR1010 QFN firmware.
When selected in firmware PIO[0] is assigned to a UART_TX output and PIO[1] is assigned to a UART_RX input,
see Section 1.2.
The UART CTS and RTS signals can be assigned to any PIO pin by the on-chip firmware.
Note:
To communicate with the UART at its maximum data rate using a standard PC, the PC requires an accelerated
serial port adapter card.
Table 5.1 shows the possible UART settings for the CSR1010 QFN.
Parameter Possible Values
Baud rate Minimum
1200 baud (≤2%Error)
9600 baud (≤1%Error)
Maximum 2Mbaud (≤1%Error)
Flow control CTS / RTS
Parity None, Odd or Even
Number of stop bits 1 or 2
Bits per byte 8
Table 5.1: Possible UART Settings
5.1.1.1 UART Configuration While in Deep Sleep
The maximum baud rate is 9600 baud during deep sleep.
5.2 Master I²C Interface
The master I²C interface communicates to EEPROM, external peripherals or sensors. An external EEPROM
connection can hold the program code externally to the CSR1010 QFN. The maximum clock speed is 400kHz.

Data Sheet
Figure 5.1 shows an example of an EEPROM connected to the I²C interface where I2C_SCL, I2C_SDA and PIO[2]
are connected to the external EEPROM. The PIO[2] pin supplies the power to the EEPROM supply pin, e.g. VDD.
At boot-up, if there is no valid ROM image in the CSR1010 QFN ROM area the CSR1010 QFN tries to boot from
the I²C interface, see Figure 5.3. This involves reading the code from the external EEPROM and loading it into the
internal CSR1010 QFN RAM.

CSR1010 QFN
Data Sheet
5.4 Programming and Debug Interface
Important Note:
The CSR1010 QFN debug SPI interface is available in SPI slave mode to enable an external MCU to program
and control the CSR1010 QFN, generally via libraries or tools supplied by CSR. The protocol of this interface
is proprietary. The 4 SPI debug lines directly support this function.
The SPI programs, configures and debugs the CSR1010 QFN. It is required in production. Ensure the 4 SPI
signals are brought out to either test points or a header.
Take SPI_PIO#_SEL high to enable the SPI debug feature on PIO[8:5].
CSR1010 QFN uses a 16-bit data and 16-bit address programming and debug interface. Transactions occur when
the internal processor is running or is stopped.
Data is written or read one word at a time, or the auto-increment feature is available for block access.
5.4.1 Instruction Cycle
The CSR1010 QFN is the slave and receives commands on DEBUG_MOSI and outputs data on DEBUG_MISO.
Table 5.3 shows the instruction cycle for a SPI transaction.
1Reset the SPI interface Hold DEBUG_CS# high for 2 DEBUG_CLK cycles
2Write the command word Take DEBUG_CS# low and clock in the 8-bit command
3Write the address Clock in the 16-bit address word
4Write or read data words Clock in or out 16-bit data word(s)
5Termination Take DEBUG_CS# high
Table 5.3: Instruction Cycle for a SPI Transaction
With the exception of reset, DEBUG_CS# must be held low during the transaction. Data on DEBUG_MOSI is clocked
into the CSR1010 QFN on the rising edge of the clock line DEBUG_CLK. When reading, CSR1010 QFN replies to
the master on DEBUG_MISO with the data changing on the falling edge of the DEBUG_CLK. The master provides
the clock on DEBUG_CLK. The transaction is terminated by taking DEBUG_CS# high.
The auto increment operation on the CSR1010 QFN cuts down on the overhead of sending a command word and
the address of a register for each read or write, especially when large amounts of data are to be transferred. The
auto increment offers increased data transfer efficiency on the CSR1010 QFN. To invoke auto increment,
DEBUG_CS# is kept low, which auto increments the address, while providing an extra 16 clock cycles for each extra
word written or read.
5.4.2 Multi-slave Operation
Do not connect the CSR1010 QFN in a multi-slave arrangement by simple parallel connection of slave MISO lines.
When CSR1010 QFN is deselected (DEBUG_CS# = 1), the DEBUG_MISO line does not float. Instead,
CSR1010 QFN outputs
0
if the processor is running or
1
if it is stopped.

Figure 6.1: Voltage Regulator Configuration
6.1 Switch-mode Regulator
The switch-mode regulator generates the main rail from the battery supply, VDD_BAT_SMPS. The main rail supplies
the lower regulated voltage to a further digital linear regulator and also to the analogue sections of the CSR1010 QFN.
The switch-mode regulator generates typically 1.35V.
6.2 Low-voltage VDD_DIG Linear Regulator
The integrated low-voltage VDD_DIG linear regulator powers the CSR1010 QFN digital circuits. The input voltage
range is 0.65V to 1.35V. It can supply programmable voltages of 0.65V to 1.20V to the digital area of the
CSR1010 QFN. The maximum output current for this regulator is 30mA.
Connect a minimum 470nF low ESR capacitor, e.g. MLC, to the VDD_CORE output pin. Software controls the output
voltage.
Important Note:
This regulator is only for CSR internal use. Section 7 shows CSR's recommended circuit connection.

.
■
EU REACH, Regulation (EC) No 1907/2006
1
:
■
List of substances subject to authorisation (Annex XIV)
■
Restrictions on the manufacture, placing on the market and use of certain dangerous substances,
preparations and articles (Annex XVII). This Annex now includes requirements that were contained
within EU Directive, 76/769/EEC. There are many substance restrictions within this Annex, including,
but not limited to, the control of use of Perfluorooctane sulfonates (PFOS).
■
When requested by customers, notification of substances identified on the Candidate List as
Substances of Very High Concern (SVHC)

■
EU Packaging and Packaging Waste, Directive 94/62/EC
1
■
Montreal Protocol on substances that deplete the ozone layer.
■
Conflict minerals, Section 1502, Dodd-Frank Wall Street Reform and Consumer Protection act, which
affects columbite-tantalite (coltan / tantalum), cassiterite (tin), gold, wolframite (tungsten) or their
derivatives. CSR is a fabless semiconductor company: all manufacturing is performed by key suppliers.
CSR have mandated that the suppliers shall not use materials that are sourced from "conflict zone mines"
but understand that this requires accurate data from the EICC programme. CSR shall provide a complete
EICC / GeSI template upon request.
CSR has defined the "CSR Green" standard based on current regulatory and customer requirements including free
from bromine, chlorine and antimony trioxide.
Products and shipment packaging are marked and labelled with applicable environmental marking symbols in
accordance with relevant regulatory requirements.
This identifies the main environmental compliance regulatory restrictions CSR specify. For more information on the
full "CSR Green" standard, contact product.compliance@csr.com.
