MAX32630：Ultra-Low Power, High-Performance Cortex-M4F Microcontroller for Wearables

Ultra-Low Power Cortex-M4F Ideally Suited for Emerging Wearable Medical and Fitness Applications

The MAX32630/MAX32631 is an ARM® Cortex® -M4F 32-bit microcontroller with a floating point unit, ideal for the emerging category of wearable medical and fitness applications. The architecture combines ultra-low power high-efficiency signal processing functionality with significantly reduced power consumption and ease of use. 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, as well as 1-Wire® master and USB, allow for interconnection to a wide variety of external sensors. A four-input, 10-bit ADC with selectable references is available to monitor analog input from external sensors and meters. The small 100-ball WLP package provides a tiny, 4.37mm x 4.37mm footprint. The MAX32630/MAX32631 include a hardware AES engine. The MAX32631 is a secure version of the MAX32630. It incorporates a trust protection unit (TPU) with encryption and advanced security features. These features include a modular arithmetic accelerator (MAA) for fast ECDSA, a hardware PRNG entropy generator, and a secure boot loader.
