Bluetooth wireless SoC

The EFR32BG29 wireless SoC from Silicon Labs is a highly efficient, high memory, low-power, and ultra compact SoC designed for secure and high-performance wireless networking for IoT devices. It features 1 MB Flash and 256 kB RAM, DC/DC Boost to support multiple battery chemistries and allow operation down to 1,2 V, and a Coulomb counter for accurate battery level monitoring.

The SoC is also designed for Secure Vault High that provides advanced security features, making it ideal for applications and sectors that have rigorous and stringent security and privacy standards. Some applications include battery powered sensors, asset trackers, tooth implants, CGMS, and wearables.

The chip is powered by a 32-bit ARM Cortex-M33 running at 76,8 MHz. A DSP instruction and floating-point unit is integrated for efficient signal processing. The 2,4 GHz radio has a sensitivity of -99 dBm at 1 Mbit/s throughput and a Tx power of up to 8 dBm.

The SoC has a wide range of peripherals integrated including a 16-bit ADC and analogue comparator, and up to 26 GPIO with output state retention and asynchronous interrupts. Three 16-bit timers and two 32-bit timers are available with one 32-bit real-time counter. Two USART ports are integrated, as are two I2C interfaces with SMBus support.
