LCD driver for segment-type LCDs
BU9728AKV
The BU9728AKV is a segment-type LCD system driver which can accommodate microcomputer control and a serial
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)
2) Display RAM: Internal, 128 bits. (up to 128 seg-
ments can be displayed)
3) Internal power supply circuit for LCD drive.
4) Display duty: 1 / 4
5) Can be driven with low voltage and low current dissi-
pation.
