3.2.2 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 con­sumption. 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.

to 6. Layout Guidelines for PCB layout and antenna integration
guidelines for optimal performance. Typical efficiency gain is ex­pected to be from -3.5 to -5.5 dB.

3.2.3 Packet and State Trace

The BGM13P 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

3.2.4 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 num­ber generator algorithms such as Fortuna.

System Overview

3.3 Power

The BGM13P 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 for +8 dBm Devices on page 9 shows how the exter­nal and internal supplies of the module are connected.

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.

System Overview

3.3.3 Power Domains

The BGM13P has two peripheral power domains for operation in EM2 and lower. If all of the peripherals in a peripheral power domain
are configured as unused, the power domain for that group will be powered off in the low-power mode, reducing the overall current
consumption of the device.

3.4 General Purpose Input/Output (GPIO)

BGM13P 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 sev­eral 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 BGM13P. Individual enabling and disabling of clocks to all peripheral
modules is performed 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 and Crystals

The BGM13P fully integrates several oscillator sources and two crystals.

• The high-frequency crystal oscillator (HFXO) and integrated 38.4 MHz crystal provide a precise timing reference for the MCU and
radio.

• The low-frequency crystal oscillator (LFXO) and integrated 32.768 kHz crystal provide an accurate timing reference for low energy
modes and the real-time-clock circuits.

• 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 Viewer port with a wide frequency range.

• An integrated low frequency 32.768 kHz RC oscillator (LFRCO) for low power operation where high 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 con­sumption in low energy modes.

Bluetooth ® Module Data Sheet

System Overview

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 Wide Timer/Counter (WTIMER)

WTIMER peripherals function just as TIMER peripherals, but are 32 bits wide. They keep track of timing, count events, generate PWM
outputs and trigger timed actions in other peripherals through the PRS system. The core of each WTIMER is a 32-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 WTIMER 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 WTIMER_0 only.

3.6.3 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 oscilla­tors 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 down to EM4H.

A secondary RTC is used by the RF protocol stack for event scheduling, leaving the primary RTCC block available exclusively for appli­cation software.

3.6.4 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 wave­forms with minimal software intervention. The LETIMER is connected to the Real Time Counter and Calendar (RTCC), and can be con­figured to start counting on compare matches from the RTCC.

3.6.5 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 inter­rupt periods, facilitating flexible ultra-low energy operation.

3.6.6 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.

3.6.7 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.

System Overview

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 sup­porting:

• 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 trans­fers. 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 periph­erals which in turn perform actions in response. Edge triggers and other functionality such as simple logic operations (AND, OR, NOT)
can be applied by the PRS to the signals. The PRS allows peripheral to act autonomously without waking the MCU core, saving power.

3.7.5 Low Energy Sensor Interface (LESENSE)

The Low Energy Sensor Interface LESENSETM is a highly configurable sensor interface with support for up to 16 individually configura­ble sensors. By controlling the analog comparators, ADC, and DAC, LESENSE is capable of supporting a wide range of sensors and
measurement schemes, and can for instance measure LC sensors, resistive sensors and capacitive sensors. LESENSE also includes a
programmable finite state machine which enables simple processing of measurement results without CPU intervention. LESENSE is
available in energy mode EM2, in addition to EM0 and EM1, making it ideal for sensor monitoring in applications with a strict energy
budget.

3.8 Security Features

System Overview

3.8.2 Crypto Accelerator (CRYPTO)

The Crypto Accelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. EFR32 devices sup­port AES encryption and decryption with 128- or 256-bit keys, ECC over both GF(P) and GF(2m), SHA-1 and SHA-2 (SHA-224 and

SHA-256).

Supported block cipher modes of operation for AES include: ECB, CTR, CBC, PCBC, CFB, OFB, GCM, 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 CRYPTO1 block 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 signals for DMA read and write operations.

3.8.3 True Random Number Generator (TRNG)

The TRNG module is a non-deterministic random number generator based on a full hardware solution. The TRNG is validated with
NIST800-22 and AIS-31 test suites as well as being suitable for FIPS 140-2 certification (for the purposes of cryptographic key genera­tion).

3.8.4 Security Management Unit (SMU)

The Security Management Unit (SMU) allows software to set up fine-grained security for peripheral access, which is not possible in the
Memory Protection Unit (MPU). Peripherals may be secured by hardware on an individual basis, such that only priveleged accesses to
the peripheral's register interface will be allowed. When an access fault occurs, the SMU reports the specific peripheral involved and
can optionally generate an interrupt.

3.9 Analog

3.9.1 Analog Port (APORT)

The Analog Port (APORT) is an analog interconnect matrix allowing access to many analog modules on a flexible selection of pins.
Each APORT bus consists of analog switches connected to a common wire. Since many clients can operate differentially, 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 high­er. 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 Msps. 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 Capacitive Sense (CSEN)

The CSEN module is a dedicated Capacitive Sensing block for implementing touch-sensitive user interface elements such a switches
and sliders. The CSEN module uses a charge ramping measurement technique, which provides robust sensing even in adverse condi­tions including radiated noise and moisture. The module can be configured to take measurements on a single port pin or scan through
multiple pins and store results to memory through DMA. Several channels can also be shorted together to measure the combined ca­pacitance or implement wake-on-touch from very low energy modes. Hardware includes a digital accumulator and an averaging filter,
as well as digital threshold comparators to reduce software overhead.

System Overview

3.9.5 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 full-scale current is programmable between 0.05 µA and 64 µA with
several ranges consisting of various step sizes.

3.9.6 Digital to Analog Converter (VDAC)

The Digital to Analog Converter (VDAC) can convert a digital value to an analog output voltage. The VDAC is a fully differential, 500
ksps, 12-bit converter. The opamps are used in conjunction with the VDAC, to provide output buffering. One opamp is used per single­ended channel, or two opamps are used to provide differential outputs. The VDAC may be used for a number of different applications
such as sensor interfaces or sound output. The VDAC can generate high-resolution analog signals while the MCU is operating at low
frequencies and with low total power consumption. Using DMA and a timer, the VDAC can be used to generate waveforms without any
CPU intervention. The VDAC is available in all energy modes down to and including EM3.

3.9.7 Operational Amplifiers

The opamps are low power amplifiers with a high degree of flexibility targeting a wide variety of standard opamp application areas, and
are available down to EM3. With flexible built-in programming for gain and interconnection they can be configured to support multiple
common opamp functions. All pins are also available externally for filter configurations. Each opamp has a rail to rail input and a rail to
rail output. They can be used in conjunction with the VDAC module or in stand-alone configurations. The opamps save energy, PCB
space, and cost as compared with standalone opamps because they are integrated on-chip.

3.10 Reset Management Unit (RMU)

The RMU is responsible for handling reset of the BGM13P. A wide range of reset sources are available, including several power supply
monitors, pin reset, software controlled reset, core lockup reset, and watchdog reset.

3.11 Core and Memory

3.11.1 Processor Core

The ARM Cortex-M processor includes a 32-bit RISC processor integrating the following features and tasks in the system:

• ARM Cortex-M4 RISC processor achieving 1.25 Dhrystone MIPS/MHz

• Memory Protection Unit (MPU) supporting up to 8 memory segments

• Up to 512 kB flash program memory

• Up to 64 kB RAM data memory

• Configuration and event handling of all modules

• 2-pin Serial-Wire debug interface

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 en­ergy modes EM0 Active and EM1 Sleep.

3.11.3 Linked Direct Memory Access Controller (LDMA)

The Linked Direct Memory Access (LDMA) controller allows the system to perform memory operations independently of software. This
reduces both energy consumption and software workload. The LDMA allows operations to be linked together and staged, enabling so­phisticated operations to be implemented.

Note:

1. When a GPIO pin is routed to the analog module through the APORT, the maximum voltage = IOVDD.

2. Valid for IOVDD in valid operating range or when IOVDD is undriven (high-Z). If IOVDD is connected to a low-impedance source
below the valid operating range (e.g. IOVDD shorted to VSS), the pin voltage maximum is IOVDD + 0.3 V, to avoid exceeding the
maximum IO current specifications.

3. To operate above the IOVDD supply rail, over-voltage tolerance must be enabled according to the GPIO_Px_OVTDIS register.
Pins with over-voltage tolerance disabled have the same limits as Standard GPIO.
