OM5232 General 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.

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 unctions 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 0.75ms and 40% in 1.5ms. Multiply and divide instructions require 3ms.
