The Precision32™ family offers a full lineup of footprint compatible ARM® Cortex™-M3 based 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. The SiM3U1xx family includes USB 2.0 to easily add USB to your embedded designs.

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 data sheet. Combining the world’s best peripherals with the de facto standard 32-bit core makes designing with an MCU easier than ever.
