DESCRIPTION
The 87C652/87C654 single-chip 8-Bit
microcontroller is manufactured in an
advanced CMOS process and is a derivative
of the 80C51 microcontroller family. The
87C652/87C654 has the same instruction
set as the 80C51. Three versions of the
derivative exist:
80C652—ROMless
83C652/83C654—8 Kbyte, 16 Kbyte ROM
87C652/87C654—8 Kbyte, 16 Kbyte OTP
The ROMless and ROM are in separate
datasheets.
This device provides architectural
enhancements that make it applicable in a
variety of applications for general control
systems. The 87C654 contains a non-volatile
16k
× 8 EPROM and the 87C652 contains an
8k x 8 EPROM. Both have a volatile 256
× 8
read/write data memory, four 8-bit I/O ports,
two 16-bit timer/event counters (identical to
the timers of the 80C51), a multi-source,
two-priority-level, nested interrupt structure,
an I2C interface, UART and on-chip oscillator
and timing circuits. For systems that require
extra capability, the 87C652/87C654 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.
