General Description

The MAX32625/MAX32626 is an ARM? Cortex?-M4F 32-bit microcontroller with an unconnected point unit, ideal for the emerging category of wearable medical and fitness applications. The architecture combines ultra-low power, high-efficiency signal processing functionality and ease of use. An internal 96MHz oscillator provides high-performance capability, and the internal 4MHz oscillator supports minimal power consumption for applications requiring always-on monitoring. The device provides 512kB of flash and 160kB of SRAM.

The device features four powerful and flexible power modes. A peripheral management unit (PMU) enables intelligent peripheral control with up to six channels to significantly reduce power consumption. Built-in dynamic clock gating and firmware-controlled power gating allows the user to optimize power for the specific application.
