Revision A2
GENERAL DESCRIPTION
The W78C54 is a derivative of the W78C52 microcontroller family that provides extended internal
ROM. The chip has 16K 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 16KB 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.
FEATURES
DC to 40 MHz extensive operating frequency
256-byte on-chip scratch pad RAM
16K-byte on-chip mask ROM
64K-byte address space for external Program Memory
64K-byte address space for external Data Memory
Three 16-bit timer/counters
Four 8-bit bit-addressable I/O ports
One extra 4-bit bit-addressable I/O port, additional INT2/ INT3
