UM321x incorporates the ARM Cortex-M0+ core
operating at a 48MHz frequency, embedded Flash memory（up
to 64Kbytes）, and supports a wide voltage operating
range of 2.0~5.5v. The chip integrates up to 12 channels of 12 bit
high-precision SAR ADC, multi-channel UART, SPI, I2C and other peripheral
interfaces, supports up to 25-channel PWM and 1-channel can bus, provides up to
51 GPIOs, and has built-in operational amplifier and comparator with the
characteristics of high integration, high anti-interference and high
reliability.
