A31G31x series – A31G313/314/316 – are designed for the main controller of various appliances. In particular, accordance with the tendency that the microcontroller is becoming more complicated and is requiring higher performance in consumer electronics, ARM high-speed 32-bit Cortex-M0+ Core is used. And to handle more features, the microcontrollers have a variety of peripheral devices and large amounts of Flash memory. Powerful and various external serial interfaces help to communicate with on-board sensors and devices.
