Low-power 32-bit MCU aids complex sensor designs

The MAX32670 microcontroller (MCU) from Maxim Integrated allows engineers to develop designs with complex sensor processing while not compromising battery life.

The device, which is in stock at Mouser Electronics, combines a flexible and adaptable power management unit, with an Arm Cortex-M4 processor that includes a floating-point unit (FPU).

The MAX32670 also provides a cost-optimal upgrade path from 8- or 16-bit microcontrollers using legacy designs.

It consumes just 40 µW/MHz in active power mode, executing commands from flash at 40 percent lower power than comparable solutions.

The MCU integrates up to 384 KBytes of flash and 160 KBytes of SRAM, allowing application and sensor code.

Ultra-reliable code execution for demanding applications is ensured through error correction coding (ECC), which is capable of single error correction and double error detection (SEC-DED) and is implemented over the entire flash, RAM, and cache.

This microcontroller is ideal for applications such as smart sensor controllers, industrial sensors, optical communication modules, secure radio modem controllers, and battery-powered medical devices.
