MAX32660

Ultra-Low Power Arm Cortex-M4 with FPU-Based Microcontroller for Wearable and IoT Sensors

DARWIN Generation U MCUs Are Perfect for Engineers Who Are Serious About Power and Performance


Please check latest availability status for a specific part variant.

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 would not dream of sending other microcontrollers.

Generation U microcontrollers are perfect for wearables and IoT applications that cannot afford to compromise power, performance or cost. The MAX32660 is an ultra-low-power, cost-effective, highly-integrated microcontroller designed for battery-powered devices and wireless sensors. It combines a flexible and versatile power management unit with the powerful Arm® Cortex®-M4 with floating point unit (FPU).

The MAX32660 enables designs with complex sensor processing without compromising battery life. It also offers legacy designs an easy and cost optimal upgrade path from 8- or 16-bit micro controllers.

The device integrates up to 256KB of flash memory and 96KB of RAM to accommodate application and sensor code.

It supports SPI, UART and I2C communication in a tiny form factor: 1.6mm x 1.6mm 16-bump WLP or 4mm x 4mm 20-pin TQFN-EP, or 3mm x 3mm 24-pin TQFN-EP.
