OM5284 CMOS single-chip 8-bit microcontrollers

OM5284 Description

INTEGRATED CIRCUITS OM5234/OM5284 CMOS single-chip 8-bit microcontrollers Preliminary specification 1996 Nov 01 Philips Semiconductors Philips Semi.
The OM5234 and OM5284 single-chip 8-bit microcontrollers are manufactured in an advanced CMOS process and are derivatives of the 80C51 microcontroller.

OM5284 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 protec

OM5284 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 mul
