80C652 Datasheet CMOS single-chip 8-bit microcontrollers

Manufacturer: NXP Semiconductors

General Description

The P80C652/83C652 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

The 80C652/83C652 has the same instruction set as the 80C51.

Three versions of the derivative exist: 83C652 — 8k bytes mask programmable ROM 80C652 — ROMless version 87C652 — EPROM version (described in a separate chapter) This device provides architectural enhancements that make it applicable in a variety of applications for general control systems.
