Analog Devices / Maxim Integrated MAX32672 ARM Cortex-M4F Microcontrollers

Analog Devices MAX32672 ARM Cortex-M4F Microcontrollers are ultra-low-power, cost-effective, highly integrated, and highly reliable 32-bit microcontrollers. The devices enable designs with complex sensor processing without compromising battery life. The MCUs combine a flexible and versatile power management unit with the powerful Arm® Cortex®-M4 processor with a floating point unit (FPU). The Analog Devices MAX32672 also offers legacy designs an easy and cost-optimal upgrade path from 8- or 16-bit microcontrollers.
