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.
The 87C552 contains a 8k
×
8 non-volatile EPROM, a 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, four-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 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. Optionally, the ADC can be operated
in Idle mode. 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.
