This paper presents a design of MCU Programmer based on CH340T adapter chip.The programmer is mainly composed by the microcontroller subsystem,CH340T conversion system and power supply system. It communicates with the host computer via USB connection;users can achieve the erasure,programming,ver ification and encryption of STC 89C/S 51XX/52XX series MCU only by simple operation by a PC GUI on the host compute.After repeated testing on STC89C52RC microcontroller,the programmer has the advantages of stablity,fast,low price and easy of use etc.
