CMOS single-chip 8-bit microcontroller
83C654
DESCRIPTION
The P83C654 Single-Chip 8-Bit
Microcontroller is manufactured in an
advanced CMOS process and is a derivative
of the 80C51 microcontroller family. The
83C654 has the same instruction set as the
80C51. Two versions of the derivative exist:
83C654 — 16k bytes mask programmable
ROM
87C654 — EPROM version (described in a
separate data sheet)
This device provides architectural
enhancements that make it applicable in a
variety of applications for general control
systems. The 83C654 contains a non-volatile
16k
×
8 read-only program memory, 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
8XC654 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(24)MHz crystal, 58% of
the instructions are executed in 0.75(0.5)µs
and 40% in 1.5(1)µs. Multiply and divide
instructions require 3(2)µs.
