Design and Realization of a Multi-EPROM Programmer

Abstract

The design and implementation of a versatile, lowcost and portable EPROM programmer is presented. In contrast to EPROM programmers dedicated to a single or few types of EPROMS, this programmer could be used to programme various types using a single EPROM socket. The hardware is built using commonly available components and is used to select appropriate pin positions and functions on the EPROM socket and deliver appropriate supply and programming voltages. The selection of the EPROM type, the process of programming, reading and displaying of the contents of an EPROM is controlled by software. The software is implemented using turbo PASCAL, version 5 on an IBM PC/AT personal computer.
