MAX32620 Ultra-Low-Power ARM Cortex-M4 with FPU-Based Microcontroller Evaluation Kit

The MAX32620 is a 32-bit RISC ARM Cortex -M4F (M4 plus Floating Point Unit) microcontroller. It is ideally suited for the emerging category of medical and fitness applications. The architecture combines high-efficiency, signal-processing functionality with low cost, and ease of use. The device features 4 powerful and flexible power modes. Built-in dynamic clock gating and firmware controlled power gating minimize power consumption for any application. Multiple SPI, UART, and I2C serial interfaces, as well as a 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 provided.
