OM5232
CMOS single-chip 8-bit microcontroller
1
December 1994
DESCRIPTION
The OM5232 Single-Chip 8-Bit Microcontroller is manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The OM5232 has the same instruction set as
the 80C51.
See also:
– OM5202 — ROMless version
– OM5234 — 16K bytes mask programmable ROM
– OM5238 — 32K bytes mask programmable ROM
This device provides architectural enhancements that make it
applicable in a variety of applications for general control systems.
The OM5232 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,
UART and on-chip oscillator and timing circuits. For systems that
require extra capability, the OM5232 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.
