Overview
INTEGRATED CIRCUITS OM5234/OM5284 CMOS single-chip 8-bit microcontrollers Preliminary specification 1996 Nov 01 Philips Semiconductors Philips Semiconductors Preliminary specification CMOS single-chip 8-bit microcontrollers OM5234/OM5284 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.
FEATURES • 80C51 central processing unit • 6k × 8 ROM • 256 × 8 RAM • Two standard 16-bit timer/cou...
