83C451 - 80C51 8-bit microcontroller family 4K/128 OTP/ROM/ROMless/ expanded I/O

Datasheet Summary

Description

The Philips 8XC451 is an I/O expanded single-chip microcontroller fabricated with Philips high-density CMOS technology.

Philips epitaxial substrate minimizes latch-up sensitivity.

Features

  • except the on-board 4k × 8 ROM. The 87C451 has 4k of EPROM on-chip as program memory and is otherwise identical to the 83C451. The 8XC451 has two software selectable modes of reduced activity for further power reduction; idle mode and power-down mode. Idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning. Power-down mode freezes the oscillator, causing all other chip functions to be inoperative while maintaining the RAM contents. PIN.
