A31L123

⯀ 产品说明

The ultra-low power A31L12x series is a microcontroller based on ARM Cortex-M0+ core with a flash memory of up to 64 Kbytes with an SRAM of 8KB. The operation voltage range of the device is from 1.65V to 3.6V. A31L12x series provide a highly flexible and cost effective solution for many battery operated applications.
The ultra-low power A31L12x series has a 16-bit timers, real timer and a calendar as well as 12-bit ADC, comparator, CRC generator, UART, USART, I2C, SPI. The series is also equipped with smart card interface, LCD driver/controller, DMA, along with POR, LVR, LVI, and an internal RC oscillator.
To reduce system power consumption, A31L12x devices also provide various power modes and ultra-low-power peripherals such as LPUART and LP timer. The A31L12x series is suitable for ultra-low power applications that require long battery life.
