Overview

The LC75850E and LC75850W are general purpose LCD drivers for use in microprocessor controlled applications such as radio tuner frequency displays.

Functions

• Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD driver techniques for a maximum of 156 segments.

• Power saving mode allows the backup function to be switched on or off and all segments to be turned off unconditionally.

• Can be controlled by three serial data lines (CE, CL, and DI) from the microprocessor. (CCB handling)

• High generality, since segment data can be displayed without going through a decoder.

• The INH pin unconditionally turns off display.

• The LCD drive bias voltage can be provided internally or externally.

• Power supply voltage: 4.5 to 8V.
