80C851 pinout datasheet


The Philips 80C851, 83C851 is a high-performance microcontroller fabricated with Philips high-density CMOS technology.

The devices 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

The devices 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 communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits.
