• 8 kbytes ROM, expandable externally to 64 kbytes

• 256 bytes 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

• An 8-bit ADC with 8 multiplexed analog inputs

• Two 8-bit resolution, Pulse Width Modulated outputs

• Five 8-bit I/O ports plus one 8-bit input port shared with

analog inputs

• Full-duplex UART compatible with the standard 80C51

• On-chip Watchdog Timer

• Oscillator frequency: 3.5 to 16 MHz.

2 GENERAL DESCRIPTION

The P80C562/P83C562 (hereafter generally referred to as

P8xC562) single-chip 8-bit microcontroller is

manufactured in an advanced CMOS process and is a

derivative of the 80C51 microcontroller family.

The P8xC562 has the same instruction set as the 80C51.

Two versions of the derivative exist:

• With 8 kbytes mask-programmable ROM

• ROMless version of the P8xC562.

This I/O intensive device provides architectural

enhancements to function as a controller in the field of

automotive electronics, specifically engine management

and gear box control.

The P8xC562 contains a non-volatile 8 kbyte read only

program memory, a volatile 256 byte read/write data

memory, six 8-bit I/O ports, two 16-bit timer/event counters

(identical to the timers of the 80C51), an additional 16-bit

timer coupled to capture and compare latches, a

fourteen-source, two-priority-level, nested interrupt

structure, an 8-input ADC, a dual DAC with pulse width

modulated outputs, a serial interface (UART), a

Watchdog Timer and on-chip oscillator and timing circuits.

For systems that require extra capability, the P8xC562 can

be expanded using standard TTL compatible memories

and logic.

The device also functions as an arithmetic processor

having facilities for both binary and BCD arithmetic plus

bit-handling capabilities. The instruction set consists of

over 100 instructions: 49 one-byte, 45 two-byte and

17 three-byte. With a 16 MHz crystal, 58% of the

instructions are executed in 0.75 µs and 40% in 1.5 µs.

Multiply and divide instructions require 3 µs.
