OM5202
ROMless 8-bit microcontroller
1
December 1994
DESCRIPTION
The OM5202 8-Bit ROMless Microcontroller is manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The OM5202 has the same instruction set as
the 80C51.
See also:
– OM5232 — 8K bytes mask programmable ROM
– 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 OM5202 contains no 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. The OM5202 can be expanded
with 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.
