DESCRIPTION
The
μ
PD78001B(A)/78002B(A) are products in the
μ
PD78002 subseries within the 78K/0 series.
The
μ
PD78001B(A)/78002B(A) have various peripheral hardware such as timer, serial interface and interrupt
function.
A one-time PROM or EPROM product, the
μ
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.
