2. General Description
2.1. Overview
The ML630Q791SDK Board is equipped with the sensor hub microcontroller “ML630Q791, various sensors include
accelerometer, Gyroscope and so on.
The ML630Q791is a high-performance 32-bit low power microcontroller optimized for sensor hub, that integrates
ARM Cortex™-M0 core, 128 KByte flash memory, 16 KByte RAM, I2C interfaces for various sensors and host
interfaces with 512 Byte logging Register in small footprint package. The ML630Q791is an ideal sensor hub
microcontroller for smart phone to separate various sensors off from its application processor and control them
effectively for reducing total system power consumption.
