Silicon Labs EFM32PG22 Gecko Reference guide

EFM32PG22 Gecko

Reference Manual

The EFM32PG22 family of microcontrollers is part of the Series 2

Gecko portfolio. EFM32PG22 MCUs are ideal for enabling energy-

friendly embedded applications.

The highly efficient solution combines a 76.8 MHz Cortex-M33 with rich analog and com-

munication peripherals to provide an industry-leading, energy efficient MCU for consum-

er and industrial applications.
