The MAX32631IWG is a new class of low-power microcontrollers designed for the rapidly growing Internet of Things (IoT). The device is incredibly intelligent, with the industry's largest memory and a massively scalable memory architecture. Thanks to wearable-grade power technology, the device can run forever. The devices are also robust enough to withstand the most advanced cyber attacks. DARWIN microcontrollers can run just about any application you can think of — no other microcontroller can.

The MAX32631IWG family of microcontrollers is ideal for wearable and IoT applications where power or performance are critical. The MAX32631IWG features an Arm® Cortex®-M4 FPU CPU with high-efficiency signal processing, ultra-low power consumption, and ease-of-use.
