The designed of USB is intended to replace many varieties of serial and parallel ports. There is also a significant advantage of its supporting hot-swappable, which means you can safely connect or disconnect the USB device in the case of the computer running to achieve a true plug and play. With the rapid development of electronics, microcontroller is widely used.However, using the microcontroller to develop product can not work without the MCU programmer. Traditional programming usually uses parallel communication to the computer, which is not available to the notebook computer, so there is a special significance to decelop the USB programmer.The USB programmer has many advantages: such as a small size, low power consumption, high reliability, versatility,fast programming characteristics etc;On the other hand, the USB interface itself can offer power, which means no power is needed. The AT89S5X microcontroller pogrammer production based on the USB interface is designed in this issue. The microcontroller programmer hardware, DC-DC boost circuit, the module of USB to serial port, the microcontrol
