DESCRIPTION
The 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The 87C552 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
The 87C552 contains a 8k

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 I
2
C-bus), a “watchdog” timer and on-chip
oscillator and timing circuits. For systems that require extra
capability, the 87C552 can be expanded using standard TTL
compatible memories and logic.
In addition, the 87C552 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 crystal,
58% of the instructions are executed in 0.75
μ
s and 40% in 1.5
μ
s.
Multiply and divide instructions require 3
μ
s.
