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))
