2. GENERAL DESCRIPTION
The P80CE559/P83CE559 (hereafter generically referred to as P8xCE559) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P8xCE559 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
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)
P83CE559 — 48 Kbytes mask programmable ROM P80CE559 — ROMless version of the P83CE559 P89CE559 — not planned any longer
Extended temperature range (–40 to +...
