INTEGRATED CIRCUITS 80C652/83C652 CMOS single-chip 8-bit microcontrollers Product specification Supersedes data of 1996 Aug 15 IC20 Data Handbook 1997 Dec 05 Philips Semiconductors Phlips Semiconductors CMOS single-chip 8-bit microcontrollers Product specification 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. The 8XC652 contains a non-volatile 8k × 8 read-only program memory, a volatile 256 × 8 read/write data memory, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the time...
