OM5234 General Description


The OM5234 and OM5284 single-chip 8-bit microcontrollers are manufactured in an advanced CMOS process and are derivatives of the 80C51 microcontroller family. The OM5234 and OM5284 are pre-programmed devices for specific applications. Unless specifically stated otherwise, all references to OM5234 apply equally to OM5284.

The OM5234 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,UART and on-chip oscillator and timing circuits.

OM5234 Features

• 80C51 central processing unit
• 6k * 8 ROM
• 256 * 8 RAM
• Two standard 16-bit timer/counters
• Four 8-bit I/O ports
• Full-duplex UART facilities
• Power control modes
Idle mode
Power-down mode
• ROM code protection
