interface. An internal 4-bit common output and LCD drive power supply circuit enable configuration of a display sys-

tem at low cost.

Applications

•

Movie projectors, car audio systems, telephones

Features

•

1) Serial interface. (8-bit length)

4) Display duty: 1 / 4

2) Display RAM: Internal, 128 bits. (up to 128 seg-

ments can be displayed)

5) Can be driven with low voltage and low current dissi-

pation.

3) Internal power supply circuit for LCD drive.
