Nuvoton’s NuMicro® M031/M032 Series: Powering Your Embedded Innovations

Selected Nuvoton NuMicro® M031/M032 ICs are up to 70% off from September 18th to October 18th while stock lasts! Grab yours today!

Nuvoton proudly presents the NuMicro® M031 and M032 Series microcontrollers, two remarkable families of microcontrollers designed to empower engineers and developers with unprecedented levels of precision and efficiency.

Whether you are working on smart appliances, industrial automation, IoT devices, or any other project that demands a high-performance, energy-efficient microcontroller, these series are poised to be your ideal choice.

These microcontrollers bring advanced features, from powerful ARM Cortex-M0+ cores to rich peripheral sets and exceptional power management capabilities. With a focus on precision, the M031 and M032 series provide robust analog and digital capabilities, ensuring the accuracy and reliability of your applications. Moreover, their low-power design extends battery life, making them perfect for battery-powered devices, remote sensors, and other energy-conscious applications.

While both the M031 and M032 series support 1.8V low-power needs, the M032 series are further empowered by the crystal-less USB 2.0 full-speed device feature for USBrelated applications.
