Preliminary specification
OM5234/OM5284
CMOS single-chip 8-bit microcontrollers
2
1996 Nov 01
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.
