General Description

In the DARWIN family, the MAX32662 is an ultra-low-power, cost-effective, highly integrated 32-bit microcontroller designed for small battery-powered devices. It combines a flexible peripheral and feature mix with the powerful Arm? Cortex?-M4 processor with floating point unit (FPU) in a small form factor.

The MAX32662 enables complex edge-based designs without compromising battery life, and it also offers legacy designs an easy and cost optimal upgrade path from 8- or 16-bit microcontrollers.

Integrating 256KB of flash memory and 80KB of SRAM, the MAX32662 easily accommodates sensor code and complex algorithms.

Peripherals include SPI, UART, I2C, I2S, CAN 2.0B, and a 12-bit ADC.

A ROM-based secure bootloader uses 256-bit elliptic curve digital signature algorithm (ECDSA-256) encryption to ensure trusted and authenticated updates of customer software.

The device is available in a 5mm x 5mm, 32-pin TQFN-EP.
