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 pare registers - A 10-bit ADC with eight multiplexed analog inputs and programmable autoscan 2. GENERAL DESCRIPTION The P80C557E6/P83C557E6 (hereafter generically referred to as P8x C557E6) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P8x C557E6 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 patible 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...
