EFM32

EFM32 is a family of 32-bit microcontroller integrated circuits by Energy Micro AS, a subsidiary of Silicon Labs. The EFM32 chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, or Cortex-M0+. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals.

EFM32 is a mixed-signal microcontroller focusing on supporting ultra low power battery operated solutions. To run from small cell batteries, EFM32 MCUs incorporates low power peripheral technology, fast response time, low latency, and autonomous operation (i.e. the CPU does not run while the peripherals communicate). The EFM32 microcontrollers are offered in various configurations.

Overview

The central processing unit in EFM32 is based on either Cortex-M4F,Cortex-M3, or Cortex-M0 processor core from ARM Holdings. EFM stands for Energy Friendly Microcontrollers and the number 32 indicates the 32-bit processor core.
