EFR32FG1P131F256GM32-C0

The EFR32FG1P131F256GM32-C0 from Silicon Labs is a member of the Flex Gecko proprietary protocol SoC family, designed for energy-friendly proprietary protocol networking in IoT devices. This single-die solution offers industry-leading energy efficiency, ultra-fast wakeup times, and a scalable power amplifier.

Key features include a 32-bit ARM Cortex-M4 core running at a maximum frequency of 40 MHz, up to 256 kB of flash program memory, and 32 kB of RAM data memory. It supports a wide operating frequency range from 110 MHz to 956 MHz, with a transmit power of up to 19.5 dBm and a sensitivity of -89.2 dBm. The device includes a robust peripheral set with up to 16 GPIOs and supports interfaces such as I2C, I2S, SMBus, SPI, and UART.

Packaged in a QFN-32 form factor, this SoC is designed for surface mounting (SMD/SMT). It operates within a temperature range of -40 C to +85 C and requires a supply voltage of 3.3 V. The integrated PA and balun contribute to its efficient RF performance, making it suitable for applications in home and building automation, metering, industrial automation, and commercial lighting.

This SoC is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1. Its compact dimensions of 5mm x 5mm x 0.85mm make it suitable for space-constrained designs.
