DESCRIPTION

The 87C528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C528 has the same instruction set as the 80C51. Three versions of the derivative exist:

? 83C528—32k bytes ROM

? 83C524—16k bytes ROM

? 80C528—ROMless version of the 83C528

? 87C528—32k bytes EPROM

? 83C524—16k bytes EPROM

This device provides architectural enhancements that make it applicable in a variety of applications in consumer, telecom and general control systems, especially in those systems which need large ROM and RAM capacity on-chip.
