SiM3C1xx 32-bit Microcontrollers

The Precision32™ family offers a full lineup of footprint compatible ARM®Cortex®-M3 based 32-bit microcontroller (MCU) devices ranging in flash size from 32–256 kB with industry-leading benefits in terms of low power, analog capabilities, configurability, rapid development, and integration.

Initializing peripherals and the patented dual-crossbar is a breeze with the Precision32 AppBuilder, a free GUI that enables developers to quickly and graphically initialize peripherals, properties, and pinouts — all without reading the datasheet. Combining the world’s best peripherals with the de facto standard 32-bit core makes designing with an MCU easier than ever.
