MOS INTEGRATED CIRCUIT

PD78001B(A), 78002B(A)

8-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The

PD78001B(A)/78002B(A) are products in the

PD78002 subseries within the 78K/0 series.

The

PD78001B(A)/78002B(A) have various peripheral hardware such as timer, serial interface and interrupt

function.

A one-time PROM or EPROM product, the

PD78P014, capable of operating in the same power supply voltage

range as that of the mask ROM product and other development tools is provided.

Functions are described in detail in the following User's Manual, which should be read when carrying out design

work.

PD78002, 78002Y Series User's Manual: IEU-1334

FEATURES
