EFM32™ PG26 32-bit Microcontrollers (MCUs)

The EFM32PG26 32-bit microcontroller (MCU) family is a software-compatible, MCU-only version of the EFR32xG26 wireless SoC platform, namely PG26. PG26 32-bit MCUs are ideal for enabling a wide range of low-power and high-performance embedded IoT applications.

The highly efficient PG26 offers a 80 MHz ARM Cortex-M33 with LCD controller, rich analog and communication peripherals, low current consumptions, and more GPIOs to address complex systems. The PG26 is also equipped with a hardware AI/ML accelerator allowing for faster inferencing at the edge with lower power consumption.
