Programmer for 87/89C51 series Flash controllers

Microcontrollers are increasingly used for switching and control applications. Consequently, there is a growing need of inexpensive programming systems. The Flash programmer described in this article handles controllers from the Intel MCS-51'M family and others (Philips, Atmel) with on-chip Flash memory, as weil as the more conventional UV-erasable types with on-chip EPROM.
