1 / 27 page  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 oscil- lator supports minimal power consumption for applica- tions 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. Multiple SPI, UART, and I2C serial interfaces are pro- vided, as well as a 1-Wire® master and USB, allowing for interconnection to a wide variety of external sensors. A four-input, 10-bit delta-sigma ADC monitors analog input from external sensors. The MAX32625L is a lower-cost version of the MAX32625, providing 256kB of flash and 128kB of SRAM. The MAX32626 is a secure version of the MAX32625. It incorporates a trust protection unit (TPU) with encryption and advanced security features. These features include a modular arithmetic accelerator (MAA) for ECDSA, a hardware PRNG entropy generator, and a secure boot loader. Both the MAX32626 and the MAX32625 provide a hardware AES engine.
