Silicon Labs 32-bit ARM® Microcontroller Family

The ARM microcontroller (MCU) architecture has become the de facto standard for 32-bit microcontrollers with its broad adoption in the embedded market and widespread support from software companies. Standardization on ARM microcontroller cores has now made it easier than ever to port code from one 32-bit microcontroller to another. As a result, the deciding factor in MCU selection is the shift from the CPU core architecture to the peripheral set and the innovative ways in which MCU vendors address system-design issues. What makes Silicon Labs' 32-bit microcontrollers different is how we applied our mixed-signal expertise to create the industry’s most flexible, energy-friendly ARM Cortex®-M4, M3, and M0+ microcontroller family, specifically designed to address the needs to today’s developers.

Based on the ARM Cortex-M processors, Silicon Labs' EFM32™ 32-bit microcontrollers redefine versatility, integration, power efficiency and ease-of-use for a broad range of embedded designs.
