Peak gain N/A

3.2.2 Wake on Radio

The Wake on Radio feature allows flexible, autonomous RF sensing, qualification, and demodulation without required MCU activity, us-

ing a subsystem of the BGM111E including the Radio Controller (RAC), Peripheral Reflex System (PRS), and Low Energy peripherals.

3.2.3 RFSENSE

The RFSENSE module generates a system wakeup interrupt upon detection of wideband RF energy at the antenna interface, providing

true RF wakeup capabilities from low energy modes including EM2, EM3 and EM4.

RFSENSE triggers on a relatively strong RF signal and is available in the lowest energy modes, allowing exceptionally low energy con-

sumption. RFSENSE does not demodulate or otherwise qualify the received signal, but software may respond to the wakeup event by

enabling normal RF reception.

Various strategies for optimizing power consumption and system response time in presence of false alarms may be employed using

available timer peripherals.

3.2.4 Packet and State Trace

The BGM111E Frame Controller has a packet and state trace unit that provides valuable information during the development phase. It

features:

• Non-intrusive trace of transmit data, receive data and state information

• Data observability on a single-pin UART data output, or on a two-pin SPI data output

• Configurable data output bitrate / baudrate

• Multiplexed transmitted data, received data and state / meta information in a single serial data stream

3.2.5 Random Number Generator

The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain.

The data is suitable for use in cryptographic applications.

Output from the random number generator can be used either directly or as a seed or entropy source for software-based random num-

ber generator algorithms such as Fortuna.

3.3 Power

The BGM111E has an Energy Management Unit (EMU) and efficient integrated regulators to generate internal supply voltages. Only a

single external supply voltage is required, from which all internal voltages are created. An integrated DC-DC buck regulator is utilized to

further reduce the current consumption.

Figure 3.2. Power Supply Configuration

3.3.1 Energy Management Unit (EMU)

The Energy Management Unit manages transitions of energy modes in the device. Each energy mode defines which peripherals and

features are available and the amount of current the device consumes. The EMU can also be used to turn off the power to unused RAM

blocks, and it contains control registers for the dc-dc regulator and the Voltage Monitor (VMON). The VMON is used to monitor multiple

supply voltages. It has multiple channels which can be programmed individually by the user to determine if a sensed supply has fallen

below a chosen threshold.

3.3.2 DC-DC Converter

The DC-DC buck converter covers a wide range of load currents and provides up to 90% efficiency in energy modes EM0, EM1, EM2

and EM3. Patented RF noise mitigation allows operation of the DC-DC converter without degrading sensitivity of radio components.

Protection features include programmable current limiting, short-circuit protection, and dead-time protection. The DC-DC converter may

also enter bypass mode when the input voltage is too low for efficient operation. In bypass mode, the DC-DC input supply is internally

connected directly to its output through a low resistance switch. Bypass mode also supports in-rush current limiting to prevent input

supply voltage droops due to excessive output current transients.

3.4 General Purpose Input/Output (GPIO)

BGM111E has up to 25 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or input.

More advanced configurations including open-drain, open-source, and glitch-filtering can be configured for each individual GPIO pin.

The GPIO pins can be overridden by peripheral connections, like SPI communication. Each peripheral connection can be routed to sev-

eral GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripherals.

The GPIO subsystem supports asynchronous external pin interrupts.

3.5 Clocking

3.5.1 Clock Management Unit (CMU)

The Clock Management Unit controls oscillators and clocks in the BGM111E. Individual enabling and disabling of clocks to all peripher-

al modules is perfomed by the CMU. The CMU also controls enabling and configuration of the oscillators. A high degree of flexibility

allows software to optimize energy consumption in any specific application by minimizing power dissipation in unused peripherals and

oscillators.

3.5.2 Internal Oscillators

The BGM111E fully integrates two crystal oscillators and four RC oscillators, listed below.

• A 38.4MHz high frequency crystal oscillator (HFXO) provides a precise timing reference for the MCU and radio.

• A 32.768 kHz crystal oscillator (LFXO) provides an accurate timing reference for low energy modes.

• An integrated high frequency RC oscillator (HFRCO) is available for the MCU system, when crystal accuracy is not required. The

HFRCO employs fast startup at minimal energy consumption combined with a wide frequency range.

• An integrated auxilliary high frequency RC oscillator (AUXHFRCO) is available for timing the general-purpose ADC and the Serial

Wire debug port with a wide frequency range.

• An integrated low frequency 32.768 kHz RC oscillator (LFRCO) can be used as a timing reference in low energy modes, when crys-

tal accuracy is not required.

• An integrated ultra-low frequency 1 kHz RC oscillator (ULFRCO) is available to provide a timing reference at the lowest energy con-

sumption in low energy modes.

3.6 Counters/Timers and PWM

3.6.1 Timer/Counter (TIMER)

TIMER peripherals keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the

PRS system. The core of each TIMER is a 16-bit counter with up to 4 compare/capture channels. Each channel is configurable in one

of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output

reflects the comparison of the counter to a programmed threshold value. In PWM mode, the TIMER supports generation of pulse-width

modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers, with optional

dead-time insertion available in timer unit TIMER_0 only.

3.6.2 Real Time Counter and Calendar (RTCC)

The Real Time Counter and Calendar (RTCC) is a 32-bit counter providing timekeeping in all energy modes. The RTCC includes a

Binary Coded Decimal (BCD) calendar mode for easy time and date keeping. The RTCC can be clocked by any of the on-board oscilla-

tors with the exception of the AUXHFRCO, and it is capable of providing system wake-up at user defined instances. When receiving

frames, the RTCC value can be used for timestamping. The RTCC includes 128 bytes of general purpose data retention, allowing easy

and convenient data storage in all energy modes.

3.6.3 Low Energy Timer (LETIMER)

The unique LETIMER is a 16-bit timer that is available in energy mode EM2 Deep Sleep in addition to EM1 Sleep and EM0 Active. This

allows it to be used for timing and output generation when most of the device is powered down, allowing simple tasks to be performed

while the power consumption of the system is kept at an absolute minimum. The LETIMER can be used to output a variety of wave-

forms with minimal software intervention. The LETIMER is connected to the Real Time Counter and Calendar (RTCC), and can be con-

figured to start counting on compare matches from the RTCC.

3.6.4 Ultra Low Power Wake-up Timer (CRYOTIMER)

The CRYOTIMER is a 32-bit counter that is capable of running in all energy modes. It can be clocked by either the 32.768 kHz crystal

oscillator (LFXO), the 32.768 kHz RC oscillator (LFRCO), or the 1 kHz RC oscillator (ULFRCO). It can provide periodic Wakeup events

and PRS signals which can be used to wake up peripherals from any energy mode. The CRYOTIMER provides a wide range of inter-

rupt periods, facilitating flexible ultra-low energy operation.

BGM111E Blue Gecko Bluetooth ® Module Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.2 | 10

3.6.5 Pulse Counter (PCNT)

The Pulse Counter (PCNT) peripheral can be used for counting pulses on a single input or to decode quadrature encoded inputs. The

clock for PCNT is selectable from either an external source on pin PCTNn_S0IN or from an internal timing reference, selectable from

among any of the internal oscillators, except the AUXHFRCO. The module may operate in energy mode EM0 Active, EM1 Sleep, EM2

Deep Sleep, and EM3 Stop.

3.6.6 Watchdog Timer (WDOG)

The watchdog timer can act both as an independent watchdog or as a watchdog synchronous with the CPU clock. It has windowed

monitoring capabilities, and can generate a reset or different interrupts depending on the failure mode of the system. The watchdog can

also monitor autonomous systems driven by PRS.

3.7 Communications and Other Digital Peripherals

3.7.1 Universal Synchronous/Asynchronous Receiver/Transmitter (USART)

The Universal Synchronous/Asynchronous Receiver/Transmitter is a flexible serial I/O module. It supports full duplex asynchronous

UART communication with hardware flow control as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with devices sup-

porting:

• ISO7816 SmartCards

• IrDA

•I2S

3.7.2 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART)

The unique LEUARTTM provides two-way UART communication on a strict power budget. Only a 32.768 kHz clock is needed to allow

UART communication up to 9600 baud. The LEUART includes all necessary hardware to make asynchronous serial communication

possible with a minimum of software intervention and energy consumption.

3.7.3 Inter-Integrated Circuit Interface (I2C)

The I2C module provides an interface between the MCU and a serial I2C bus. It is capable of acting as both a master and a slave and

supports multi-master buses. Standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates from 10

kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also available, allowing implementation of an SMBus-compliant system. The

interface provided to software by the I2C module allows precise timing control of the transmission process and highly automated trans-

fers. Automatic recognition of slave addresses is provided in active and low energy modes.

3.7.4 Peripheral Reflex System (PRS)

The Peripheral Reflex System provides a communication network between different peripheral modules without software involvement.

Peripheral modules producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer periph-

erals which in turn perform actions in response. Edge triggers and other functionality can be applied by the PRS. The PRS allows pe-

ripheral to act autonomously without waking the MCU core, saving power.

3.8 Security Features

3.8.1 GPCRC (General Purpose Cyclic Redundancy Check)

The GPCRC module implements a Cyclic Redundancy Check (CRC) function. It supports both 32-bit and 16-bit polynomials. The sup-

ported 32-bit polynomial is 0x04C11DB7 (IEEE 802.3), while the 16-bit polynomial can be programmed to any value, depending on the

needs of the application.

BGM111E Blue Gecko Bluetooth ® Module Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.2 | 11

3.8.2 Crypto Accelerator (CRYPTO)

The Crypto Accelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. It supports AES en-

cryption and decryption with 128- or 256-bit keys and ECC over both GF(P) and GF(2m), SHA-1 and SHA-2 (SHA-224 and SHA-256).

Supported modes of operation for AES include: ECB, CTR, CBC, PCBC, CFB, OFB, CBC-MAC, GMAC and CCM.

Supported ECC NIST recommended curves include P-192, P-224, P-256, K-163, K-233, B-163 and B-233.

The CRYPTO is tightly linked to the Radio Buffer Controller (BUFC) enabling fast and efficient autonomous cipher operations on data

buffer content. It allows fast processing of GCM (AES), ECC and SHA with little CPU intervention. CRYPTO also provides trigger sig-

nals for DMA read and write operations.

3.9 Analog

3.9.1 Analog Port (APORT)

The Analog Port (APORT) is an analog interconnect matrix allowing access to analog modules ADC, ACMP, and IDAC on a flexible

selection of pins. Each APORT bus consists of analog switches connected to a common wire. Since many clients can operate differen-

tially, buses are grouped by X/Y pairs.

3.9.2 Analog Comparator (ACMP)

The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indicating which input voltage is high-

er. Inputs are selected from among internal references and external pins. The tradeoff between response time and current consumption

is configurable by software. Two 6-bit reference dividers allow for a wide range of internally-programmable reference sources. The

ACMP can also be used to monitor the supply voltage. An interrupt can be generated when the supply falls below or rises above the

programmable threshold.

3.9.3 Analog to Digital Converter (ADC)

The ADC is a Successive Approximation Register (SAR) architecture, with a resolution of up to 12 bits at up to 1 MSamples/s. The

output sample resolution is configurable and additional resolution is possible using integrated hardware for averaging over multiple

samples. The ADC includes integrated voltage references and an integrated temperature sensor. Inputs are selectable from a wide

range of sources, including pins configurable as either single-ended or differential.

3.9.4 Digital to Analog Current Converter (IDAC)

The Digital to Analog Current Converter can source or sink a configurable constant current. This current can be driven on an output pin

or routed to the selected ADC input pin for capacitive sensing. The current is programmable between 0.05 µA and 64 µA with several

ranges with various step sizes.

3.10 Reset Management Unit (RMU)

The RMU is responsible for handling reset of the BGM111E. A wide range of reset sources are available, including several power sup-

ply monitors, pin reset, software controlled reset, core lockup reset and watchdog reset.

3.11.2 Memory System Controller (MSC)

The Memory System Controller (MSC) is the program memory unit of the microcontroller. The flash memory is readable and writable

from both the Cortex-M and DMA. The flash memory is divided into two blocks; the main block and the information block. Program code

is normally written to the main block, whereas the information block is available for special user data and flash lock bits. There is also a

read-only page in the information block containing system and device calibration data. Read and write operations are supported in en-

ergy modes EM0 Active and EM1 Sleep.

3.11.3 Linked Direct Memory Access Controller (LDMA)

The Linked Direct Memory Access (LDMA) controller features 8 channels capable of performing memory operations independently of

software. This reduces both energy consumption and software workload. The LDMA allows operations to be linked together and stag-

ed, enabling sophisticated operations to be implemented.

6. Layout Guidelines

For optimal performance of the BGM111E, please follow the PCB layout guidelines and ground plane recommendations indicated in

this section.

6.1 Recommended Placement on the Application PCB

For optimal performance of the BGM111E module, please follow these guidelines:

• Connect all ground pads directly to a solid ground plane.

• Place the ground vias as close to the ground pads as possible.

6.2 Effect of Plastic and Metal Materials

Plastic can be in close proximity but not physically touching the antenna. Consult your antenna data sheet and design guidelines for

details.

Any metallic objects in close proximity to the antenna will prevent the antenna from radiating freely.Consult your antenna data sheet

and design guidelines for details.

6.3 Locating the Module Close to Human Body

Placing the antenna in touch or very close to the human body will negatively impact antenna efficiency and reduce range. Consult your

antenna data sheet and design guidelines for details.

7.2 Alternate Functionality Pinout

A wide selection of alternate functionality is available for multiplexing to various pins. The following table shows the name of the alter-

nate functionality in the first column, followed by columns showing the possible LOCATION bitfield settings.

Note: Some functionality, such as analog interfaces, do not have alternate settings or a LOCATION bitfield. In these cases, the pinout

is shown in the column corresponding to LOCATION 0.

10. Soldering Recommendations

10.1 Soldering Recommendations

This section describes the soldering recommendations regarding BGM111E Module.

BGM111E is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal

mass of the entire populated PCB, heat transfer efficiency of the oven, and particular type of solder paste used.

• Refer to technical documentations of particular solder paste for profile configurations.

• Avoid usining more than two reflow cycles.

• Aperture size of the stencil should be 1:1 with the pad size.

• A no-clean, type-3 solder paste is recommended.

• For further recommendation, please refer to the JEDEC/IPC J-STD-020, IPC-SM-782 and IPC 7351 guidelines.

11.3 FCC

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

• This device may not cause harmful interference, and

• This device must accept any interference received, including interference that may cause undesirable operation.

Any changes or modifications not expressly approved by Silicon Labs could void the user’s authority to operate the equipment.

FCC RF Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specif-

ic operating instructions for satisfying RF exposure compliance. This transmitter meets both portable and mobile limits as demonstrated

in the RF Exposure Analysis.

OEM Responsibilities to comply with FCC Regulations:

The BGM111E Bluetooth module has been certified for integration into products only by OEM integrators under the following condition:

• The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accord-

ance with FCC multi-transmitter product procedures.

As long as the conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible

for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device

emissions, PC peripheral requirements, etc.).

Note:

In the event that this condition cannot be met (for certain configurations or co-location with another transmitter), then the FCC authori-

zation is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator

will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

End Product Labeling

The BGM111E Bluetooth module is labeled with its own FCC ID. If the FCC ID is not visible when the module is installed inside another

device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In

that case, the final end product must be labeled in a visible area with the following:

"Contains Transmitter Module FCC ID: QOQBGM111"

"Contains FCC ID: QOQBGM111"

The BGM111E Bluetooth module is labeled with its own IC ID. If the IC ID is not visible when the module is installed inside another

device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In

that case, the final end product must be labeled in a visible area with the following:

"Contains Transmitter Module IC: 5123A-BGM111"

"Contains IC: 5123A-BGM111"

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or

change RF related parameters in the user manual of the end product.

IC (Francais)

Cet émetteur radio (IC : 5123A-BGM111) a reçu l'approbation d'Industrie Canada pour une exploitation avec l'antenne puce incorporée.

Il est strictement interdit d'utiliser d'autres types d'antenne avec cet appareil. Le présent appareil est conforme aux CNR d’Industrie

Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes:

• L’appareil ne doit pas produire de brouillage;

• L’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre

le fonctionnement.

Déclaration relative à l'exposition aux radiofréquences (RF)

Les limites applicables à l’exemption de l’évaluation courante du DAS sont énoncées dans le CNR 102, 5e édition. L'appareil

BGM111E répond aux exigences données quand la distance de séparation minimum par rapport au corps humain est inférieure ou

égale à 15 mm. L'évaluation de l'exposition aux RF ou du DAS n'est pas requise quand la distance de séparation est de 15 mm ou

plus. Si ladistance de séparation est inférieure à 15 mm, il incombe à l'intégrateur FEO d'évaluer le DAS.

Responsabilités du FEO ayant trait à la conformité avec les règlements IC

Le module BGM111E a été certifié pour une intégration dans des produits uniquement par les intégrateurs FEO dans les conditions

suivantes:

• La ou les antennes doivent être installées de telle façon qu'une distance de séparation minimum de 15 mm soit maintenue entre le

• radiateur (antenne) et toute personne à tout moment.

• Le module émetteur ne doit pas être installé au même endroit ou fonctionner conjointement avec toute autre antenne ou émetteur.

Dès lors que les deux conditions ci-dessus sont respectées, d'autres tests de l'émetteur ne sont pas obligatoires. Cependant, il in-

combe toujours à l'intégrateur FEO de tester la conformité de son produit final vis-à-vis de toute exigence supplémentaire avec ce mod-

ule installé (par exemple, émissions de dispositifs numériques, exigences relatives aux matériels périphériques PC, etc).

Note:

S'il s'avère que ces conditions ne peuvent être respectées (pour certaines configurations ou la colocation avec un autre émetteur),

alors l'autorisation IC n'est plus considérée comme valide et l'identifiant IC ne peut plus être employé sur le produit final. Dans ces

circonstances, l'intégrateur FEO aura la responsabilité de réévaluer le produit final (y compris l'émetteur) et d'obtenir une autorisation

IC distincte.

Étiquetage du produit final

L'étiquette du module BGM111E porte son propre identifiant IC. Si l'identifiant IC n'est pas visible quand le module est installé à l'intér-

ieur d'un autre appareil, l'extérieur de l'appareil dans lequel le module est installé doit aussi porter une étiquette faisant référence au

module qu'il contient. Dans ce cas, une étiquette comportant les informations suivantes doit être collée sur une partie visible du produit

final.

"Contient le module émetteur IC: 5123A-BGM111"

"Contient IC : 5123A-BGM111"

L'intégrateur FEO doit être conscient de ne pas fournir d'informations à l'utilisateur final permettant d'installer ou de retirer ce module

RF ou de changer les paramètres liés aux RF dans le mode d'emploi du produit final.

11.5 Japan

The BGM111E is certified in Japan with certification number 209-J00240.

It is recommended that a manufacturer who integrates a radio module in their host equipment will place the certification mark and certif-

ication number (the same marking/number as depicted on the label of the radio module) on the outside of the host equipment. The

certification mark and certification number must be placed close to the text in the Japanese language which is provided below.

Figure 11.1. Certification Text to be Placed on the Outside Surface of the Host Equipment

Translation of the text in the above figure:

“This equipment contains specified radio equipment that has been certified to the Technical Regulation Conformity Certification under

the Radio Law.”

This change in the Radio Law has been made in order to enable users of the combination of host and radio module to verify if they are

actually using a radio device which is approved for use in Japan.

Figure 11.2. The Certification Mark to be Placed on the Outside Surface of the Host Equipment

The "Giteki" marking shown in the next figure must be affixed to an easily noticeable section of the specified radio equipment. Note that

additional information may be required if the device is also subject to a telecom approval.

Figure 11.3. The Certification Mark ("Giteki") dimensions

The diameter of the mark must be 5 mm or greater. If the volume of the certified equipment is less than 100 cc, the diameter of the

mark may be 3 mm or greater.
