Mixed-Signal Precision32™ 32-Bit Microcontroller Family Silicon Labs' Precision32™ 32-bit microcontroller (MCU) family is engineered to make your job easier. The Precision32 MCUs provide a highly integrated and flexible architecture, a rich peripheral set and ultra-low-power consumption. The ultra-low-power SiM3L1xx, SiM3U1xx and SiM3C1xx 32-bit MCUs deliver an unmatched combination of power efficiency, performance and lower component costs for a wide variety of applications. Silicon Labs' 32-bit microcontroller family is based on the ARM® Cortex™-M3 core, and is supported by free, but powerful Eclipse-based development tools that include a full compiler, debugger, and AppBuilder rapid prototyping utility and "power aware" tools to help you optimize your system power. The Precision32 family includes USB and non-USB devices with 32–256 kB flash, 8–32 kB RAM and 40–92 pin packages. Download the Microcontroller Selector Guide
