Date Published August 1996 P
Printed in Japan
The
PD78044H,
PD78045H, and
PD78046H are
PD78044H sub-series products in the 78K/0 series.
These microcomputers are advanced models of the
PD78044A sub-series, featuring the added N-ch open-drain
I/O ports.
In addition, the
PD78P048B (one-time PROM or EPROM model) that can operate in the same voltage range as
that of the mask ROM models, and various development tools are provided.
The functions of these microcomputers are described in detail in the following User's Manual. Be sure
to read this manual when you design a system using any of these microcomputers.
