DESCRIPTION
The 87C654 Single-Chip 8-Bit Microcontroller
is manufactured in an advanced CMOS
process and is a derivative of the 80C51
microcontroller family. The 87C654 has the
same instruction set as the 80C51. Two
versions of the derivative exist:
83C654—16k bytes mask programmable
ROM
87C654—EPROM version
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, 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 I
2
C interface,
UART and on-chip oscillator and timing
circuits. For systems that require extra
capability, the 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 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.
