MOS INTEGRATED CIRCUIT

µPD78044H, 78045H, 78046H

8-BIT SINGLE-CHIP MICROCOMPUTER

The µPD78044H, µPD78045H, and µPD78046H are µPD78044H sub-series products in the 78K/0 series.

These microcomputers are advanced models of the µPD78044A sub-series, featuring the added N-ch open-drain

I/O ports.

In addition, the µPD78P048B (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.
