General Description
DARWIN is a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT). They are smart, with the biggest memories in their class and a massively scalable memory architecture. They run forever, thanks to wearable-grade power technology. They are also tough enough to withstand the most advanced cyberattacks. DARWIN microcontrollers are designed to run any application imaginable—in places where you wouldn’t dream of sending other microcontrollers.
Generation U microcontrollers are perfect for wearables and IoT applications that cannot afford to compromise power or performance. The MAX32625/MAX32626 feature an Arm® Cortex®-M4 with FPU CPU that delivers high-efficiency signal processing, ultra-low power consumption and ease of use.
