XHSC HC32F005C6UA-SFN20TR

HC32F003 Series / HC32F005 Series are low pin count, wide voltage range MCUs. They integrate a 12-bit 1Msps high-precision SAR ADC along with rich communication peripherals including comparators, multiple UART, SPI, and I2C interfaces, featuring high integration, strong noise immunity, and high reliability. These products are based on the Cortex-M0+ core, compatible with industry-proven Keil & IAR development and debugging tools, supporting C language, assembly language, and assembly instructions.
