DESCRIPTION

The 80C552/83C552 (hereafter generically

referred to as 8XC552) Single-Chip 8-Bit

Microcontroller is manufactured in an

advanced CMOS process and is a derivative

of the 80C51 microcontroller family. The

8XC552 has the same instruction set as the

80C51. Three versions of the derivative exist:

ROM

separate chapter)

The 8XC552 contains a non-volatile 8k

× 8

read-only program memory (83C552), a

volatile 256

× 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 compare latches, a 15-source,

two-priority-level, nested interrupt structure,

an 8-input ADC, a dual DAC pulse width

modulated interface, two serial interfaces

on-chip oscillator and timing circuits. For

systems that require extra capability, the

8XC552 can be expanded using standard

TTL compatible memories and logic.

In addition, the 8XC552 has two software

selectable modes of power reduction—idle

mode and power-down mode. The idle mode

freezes the CPU while allowing the RAM,

timers, serial ports, and interrupt system to

continue functioning. The power-down mode

saves the RAM contents but freezes the

oscillator, causing all other chip functions to

be inoperative.

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 16MHz (24MHz)

crystal, 58% of the instructions are executed

in 0.75

µs (0.5µs) and 40% in 1.5µs (1µs).

Multiply and divide instructions require 3

µs

(2

µs).
