EFR32BG21B Gecko Wireless SoC Family Data Sheet

System Overview

3.5.3 Real Time Clock with Capture (RTCC)

The Real Time Clock with Capture (RTCC) is a 32-bit counter providing timekeeping down to EM3. The RTCC can be clocked by any of

the on-board low-frequency oscillators, and it is capable of providing system wake-up at user defined intervals.

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

cation software.

3.5.4 Back-Up Real Time Counter (BURTC)

The Back-Up Real Time Counter (BURTC) is a 32-bit counter providing timekeeping in all energy modes, including EM4. The BURTC

can be clocked by any of the on-board low-frequency oscillators, and it is capable of providing system wake-up at user defined inver-

vals.

3.5.5 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 the Peripheral Reflex System (PRS).

3.6 Communications and Other Digital Peripherals

3.6.1 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

•

3.6.2 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. Note that not all instances of I²C are avalia-

ble in all energy modes.

3.6.3 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 such as simple logic operations (AND, OR, NOT)

can be applied by the PRS to the signals. The PRS allows peripherals to act autonomously without waking the MCU core, saving pow-

er.

3.7 Secure Vault High Features

A dedicated Hardware Secure Engine containing its own CPU enables the Secure Vault High functions. It isolates cryptographic func-

tions and data from the host Cortex-M33 core and provides the following security features:

• Secure Boot with Root of Trust and Secure Loader (RTSL)

• Cryptographic Accelerator

• True Random Number Generator (TRNG)

• Secure Debug with Lock/Unlock

• DPA Countermeasures

• Secure Key Management with PUF

• Anti-Tamper

• Secure Attestation
