MOS INTEGRATED CIRCUIT

µPD78001B(A), 78002B(A)

8-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD78001B(A)/78002B(A) are products in the µPD78002 subseries within the 78K/0 series.

The µPD78001B(A)/78002B(A) have various peripheral hardware such as timer, serial interface and interrupt

function.

A one-time PROM or EPROM product, the µPD78P014, 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.

µPD78002, 78002Y Series User's Manual: IEU-1334

FEATURES

• The µPD78001B, in comparison with the 78002B, is a higher reliability device, as a result of a more comprehensive

quality assurance program (Refer to Quality Grade on NEC Semiconductor Devices (IEI-1209))

• Large on-chip ROM & RAM
