The A31R713 is a microcontroller based on ARM Cortex-M0+ core with a flash memory of up to 64KB, and an SRAM of 8KB. Operation voltage of the device is 1.8V to 5.5V. It provides a highly flexible and cost effective solution for many embedded control applications. The A31R713 has 16-bit timers, 32-bit timers, 12-bit ADC, CRC generator, UART, USART, I2C, LCD driver/controller, etc. The A31R713 also has a POR, LVR, LVI, and an internal RC oscillator. The A31R713 support sleep and deep sleep modes to reduce power consumption.
