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 +85 °C) • 4.5 to 5.5 V supply voltage range • Frequency range for 80C51–family standard oscillator: 3.5 MHz to 16 MHz • PLL oscillator with 32 kHz reference and software–selectable system clock frequency The P8xCE559 contains a non-volatile 48 Kbytes mask programmable ROM (P83CE559), a volatile 1536 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and comp
