Overview: INTEGRATED CIRCUITS P83C557E4/P80C557E4/P89C557E4 Single-chip 8-bit microcontroller Product specification Supersedes data of 1999 Feb 15 1999 Mar 02 Philips Semiconductors Philips Semiconductors Product specification Single-chip 8-bit microcontroller P83C557E4/P80C557E4/P89C557E4 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The P80C557E4/P83C557E4/P89C557E4 (hereafter generically referred to as P8xC557E4) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

The P8xC557E4 has the same instruction set as the 80C51.

Three versions of the derivative exist: • • • P83C557E4 — 32 Kbytes mask programmable ROM P80C557E4 — ROMless version of the P83C557E4 P89C557E4 — 32 Kbytes FEEPROM (Flash-EEPROM) The P8xC557E4 contains a non-volat

Key Features

  • 80C51 central processing unit 32 K × 8 ROM respectively.
