P87C552 Overview
The 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C552 has the same instruction set as the 80C51. For systems that require extra capability, the 8xC552 can be expanded using standard TTL patible memories and logic.
