Single-chip 8-bit microcontroller
Product specification
80C552/83C552
Single-chip 8-bit microcontroller with 10-bit A/D, capture/compare timer, high-speed outputs, PWM
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:
83C552—8k bytes mask programmable
ROM
80C552—ROMless version of the 83C552
87C552—8k bytes EPROM (described in a
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
(UART and I2C-bus), a “watchdog” timer and
on-chip oscillator and timing circuits. For
systems that require extra capability, the
8XC552 can be expanded using standard
TTL compatible memories and logic.
FEATURES
80C51 central processing unit
8k × 8 ROM expandable externally to 64k
bytes

to four capture registers and three compare
registers

256 × 8 RAM, expandable externally to 64k
bytes
Capable of producing eight synchronized,
timed outputs
A 10-bit ADC with eight multiplexed analog
inputs
Two 8-bit resolution, pulse width
modulation outputs
Five 8-bit I/O ports plus one 8-bit input port
shared with analog inputs

Three operating ambient temperature
ranges:
P83C552xBx: 0°C to +70°C
P83C552xFx: –40°C to +85°C
(XTAL frequency max. 24 MHz)

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 0.75µs (0.5µs) and 40% in 1.5µs (1µs).
Multiply and divide instructions require 3µs
(2µs).
