INTEGRATED CIRCUITS P83C557E6/P80C557E6 Single-chip 8-bit microcontroller Product specification 1999 Mar 02 Philips Semiconductors Philips Semiconductors Product specification Single-chip 8-bit microcontroller P83C557E6/P80C557E6 1. FEATURES 80C51 central processing unit 48 K × 8 ROM, expandable externally to 64 Kbytes ROM Code protection 1536 × 8 RAM, expandable externally to 64 Kbytes Two standard 16-bit timer/counters An additional 16-bit timer/counter coupled to four capture registers and three compare registers A 10-bit ADC with eight multiplexed analog inputs and programmable autoscan 2. GENERAL DESCRIPTION The P80C557E6/P83C557E6 (hereafter generically referred to as P8xC557E6) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P8xC557E6 has the same instruction set as the 80C51. Three versions of the derivative exist: Two 8-bit resolution, pulse width modulation outputs Five 8-bit I/O ports plus one 8-bit input port shared with analog inputs I2C-bus serial I/O port with byte oriented master and slave functions P83C557E6 — 48 Kbytes mask programmable ROM P80C557E6 — ROMless version of the P83C557E6 Full-duplex UART compatible with the standard 80C51 On-chip watchdog timer 15 interrupt sources with 2 priority levels (2 to 6 external sources possible) Extended temperature range (–40 to +85 °C) 4.5 to 5.5 V supply voltage range Frequen...
