INTEGRATED CIRCUITS 80C652/83C652 CMOS single-chip 8-bit microcontrollers Product specification IC20 Data Handbook 1996 Aug 15 Philips Semiconductors Phlips Semiconductors Product specification CMOS single-chip 8-bit microcontrollers 80C652/83C652 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.
