Product specification
80C652/83C652
DESCRIPTION
The P80C652/83C652 Single-Chip 8-Bit
Microcontroller is manufactured in an
advanced CMOS process and is a derivative
of the 80C51 microcontroller family. The
80C652/83C652 has the same instruction set
as the 80C51. Three versions of the
derivative exist:
83C652 — 8k bytes mask programmable
ROM
80C652 — ROMless version
87C652 — EPROM version (described in a
separate chapter)
This device provides architectural
enhancements that make it applicable in a
variety of applications for general control
systems. The 8XC652 contains a non-volatile
8k × 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 I2C interface, UART
and on-chip oscillator and timing circuits. For
systems that require extra capability, the
8XC652 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.
