MAX32672 32-Bit Microcontroller
Analog Devices' MAX32672 high reliability, tiny, ultra-low-power Arm® Cortex®-M4F microcontroller with 12-bit 1 MSPS ADC
ADI's MAX32672 is an ultra-low-power, cost-effective, highly integrated, and reliable 32-bit microcontroller, enabling designs with complex sensor processing without compromising battery life. It combines a flexible and versatile power management unit with the powerful Arm Cortex-M4 processor with a floating-point unit (FPU). The MAX32672 also offers legacy designs an easy and cost-optimal upgrade path from 8- or 16-bit microcontrollers.
The device integrates 1 MB of Flash and 200 KB of SRAM to accommodate application and sensor code. Error correction coding (ECC) is implemented on the entire Flash, RAM, and cache to ensure extremely reliable code execution even in the harshest of environments. Brownout detection ensures proper operation during power-down and power-up events and unexpected supply transients.
The MAX32672 evaluation kit (MAX32672EVKIT#) provides a platform for evaluating the capabilities of the MAX32672 microcontroller, which is a small, high-reliability, ultra-low-power, 32-bit microcontroller. The MAX32672 is a secure and cost-effective solution for motion/motor control, industrial sensors, and battery-powered medical devices.
