Overview

INTEGRATED CIRCUITS 83C654 CMOS single-chip 8-bit microcontroller Product specification Supersedes data of 1996 Aug 15 IC20 Data Handbook 1998 Jan 06 Philips Semiconductors Philips Semiconductors CMOS single-chip 8-bit microcontroller Product specification 83C654 DESCRIPTION The P83C654 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.
The 83C654 has the same instruction set as the 80C51.
Two versions of the derivative exist: 83C654 — 16k bytes mask programmable ROM 87C654 — EPROM version (described in a separate data sheet) This device provides architectural enhancements that make it applicable in a variety of applications for general control systems.
The 83C654 contains a non-volatile 16k × 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 timers of the 80C51), a multi-source, two-priority-level,...
