GENERAL DESCRIPTION

The MSM6779 is a LCD dot matrix segment driver. Fabricated in CMOS technology, the device

consists of 160-bit latches I and II, a 160-bit level shifter, and a 4-level driver. The MSM6779

latches the 4-bit parallel display data sent from a microcontroller or a LCD controller to generate

a LCD driving signal. This MSM6779 has a power-save function that sets all the drivers except

This driver's 3V-operation allows significant reduction in current consumption, suitable for

battery-driving. The bias voltage to specify a drive level can be supplied externally. The

MSM6779 can be used for various types of LCD panels.

FEATURES

• Logic supply voltage

: 2.7 V to 5.5 V

• LCD drive voltage

: A wide range from 14 V to 28 V

• Applicable LCD duty

: 1/64 to 1/256

• The bias voltage can be supplied externally.

• LCD outputs

: 160

• A power-save function to reduce power consumption in a large-screen LCD panel.

• A 4-bit parallel data transfer to reduces its transfer speed to 1/4 of conventional serial transfer,

providing low power consumption.

• Data transfer clock frequency

• 35mm-wide-film TCP

Tin-plating

User area
