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:

• P83CE559 — 48 Kbytes mask programmable ROM

• P80CE559 — ROMless version of the P83CE559

• P89CE559 — not planned any longer

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

• 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)

• 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

• Seconds Timer

• Software enable/disable of ALE output pulse

• Electromagnetic compatibility improvements

• Wake–up from Power–down by external or seconds interrupt
