Base on ARM Cortex-M0 , it is developed with excellent noise immunity capability and excellent encryption technology of the traditional 8051 MCU. Built-in PWM function with center/edge-align and dead time control , flexible pin alternate function selection, multiple reset Resources, High speed I/O modules and fast comparators (ACMP) can be quickly imported and applied to complex Electrical Engineering control systems with multiple sets of high-speed peripheral hardware such as UART, SPI, I2C and
