INTEGRATED CIRCUITS 80C851/83C851 CMOS single-chip 8-bit microcontroller with on-chip EEPROM Product specification Supersedes data of 1992 Nov 25 IC20 Data Handbook 1998 Jul 03 Philips Semiconductors Philips Semiconductors CMOS single-chip 8-bit microcontroller with on-chip EEPROM Product specification 80C851/83C851 DESCRIPTION The Philips 80C851/83C851 is a high-performance microcontroller fabricated with Philips high-density CMOS technology. The 80C851/83C851 has the same instruction set as the 80C51. The Philips CMOS technology combines the high speed and density characteristics of HMOS with the low power attributes of CMOS. The Philips epitaxial substrate minimizes latch-up sensitivity. The 80C851/83C851 contains a 4k × 8 ROM with mask-programmable ROM code protection, a 128 × 8 RAM, 256 × 8 EEPROM, 32 I/O lines, two 16-bit counter/timers, a seven-source, five vector, two-priority level nested interrupt structure, a serial I/O port for either multi-processor communication...
