The Precision32™ family offers a full lineup of footprint compatible ARM® Cortex™-M3 based 32-bit microcontroller 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 data sheet. Combining the world’s best peripherals with the de facto standard 32-bit core makes designing with an MCU easier than ever.
The Precision32 family also offers unique and best-in-class peripherals. Peripheral highlights include ultra-low power real time clock (RTC), analog over full voltage and temperature range, capacitive sense inputs, 5 V input regulator, motor control timers with fail safe modes and 300 mA I/O that can directly drive small motors, power FETs, LEDs, buzzers and more. Utilizing a patented dual–crossbar architecture, developers can choose their peripheral mix and select their pin location eliminating pin conflicts, simplifying PCB routing and potentially reducing the number of PCB layers needed.
