This application note describes a personal computer-based programmer forthe AT89C51/C52/LV51/LV52/C1051/C2051 Flash-based Microcontrollers. The programmer
supports all flash memory microcontroller functions, including code read, code write, chip erase, signature read, and lock bit write. When used with the AT89C51/C52/ LV51/LV52, code write, chip erase, and lock bit write may be performed at either five or twelve volts, as required by the device. Devices sporting a “-5” suffix are intended for operation at five volts, while devices lacking the suffix operate at the standard twelve volts.
The programmer connects to an IBM PC-compatible host computer through one of the host's parallel ports. Required operating voltages are produced by an integral power supply and external, wallmounted transformer.
