OM5234 datasheet


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. 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.


1. 80C51 central processing unit
2. 6k × 8 ROM
3. 256 × 8 RAM
4. Two standard 16-bit timer/counters
5. Four 8-bit I/O ports
6. Full-duplex UART facilities
7. Power control modes
(1)  Idle mode
(2)  Power-down mode

8. ROM code protection
