摘要
介绍了单片机在系统编程原理 ,讨论了几种 80 5 1核心单片机的在系统编程的引导方式。然后对电压监控系统芯片 TPS3 83 8的特性做了简单介绍。并就利用 TPS3 83 8不同接法 ,输出复位信号将有不同延时的特性实现的在系统编程电路做了具体介绍。
The principle of ISP for single chip processor is i ntroduced, and several methods that are used to make MCU enter ISP mode for seve ral different single chip processors with 8051 core are discussed.Then the circ uit, which is based on the property that TPS3838 has a different delay time with Pin CT connected pin GND or pin Vdd, is particularly introduced.
