Ultra-low power consumption, high cost performance, highly integrated, reliable 32 bit microcontroller

ADI's MAX32672 is an ultra-low-power, cost-effective, highly integrated, and reliable 32-bit microcontroller designed to enable complex sensor processing without compromising battery life. It combines a flexible and versatile power management unit with a powerful Arm Cortex-M4 processor and floating-point unit (FPU). The MAX32672 also provides a legacy design with a simple and cost-optimal upgrade path from 8-bit or 16-bit microcontrollers.

The device integrates 1mb of Flash and 200kb of SRAM to house application and sensor code. Error correction coding (ECC) is implemented across Flash, RAM, and cache to ensure very reliable execution of code even in the most hostile environments. Outage detection ensures normal operation during power-off and power-on events and unexpected power transients.

The MAX32672 Evaluation Kit (MAX32672EVKIT#) provides a platform to evaluate the capabilities of the MAX32672 microcontroller, which is a small, highly reliable, ultra-low power, 32-bit microcontroller. The MAX32672 is a safe and economical solution for motion/motor control, industrial sensors and battery powered medical devices.
