PRELIMINARY W78C516

8-BIT MICROCONTROLLER

Publication Release Date: April, 1999

- 1 -

Revision A0

GENERAL DESCRIPTION

The W78C516 is a derivative of the W78C52 microcontroller family that provides extended internal

ROM. The chip has 64K bytes of mask ROM and 256 bytes of RAM.

This device provides an enhanced architecture that makes it more powerful and suitable for a variety

of applications for general control systems. It provides on-chip 64KB mask ROM to accommodate

large program codes, 256-bytes of non-volatile on-chip RAM, four 8-bit I/O ports, one 4-bit I/O port,

three 16-bit timer/counters, eight sources with two-level interrupt structures, and on-chip oscillator

clock circuits.
