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 se gment 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.

INH and Display Control

Since the IC internal data (D1 to D156, DR, SC, and BU) is undefined when power is first applied, INH should be set
low at the same time as power is applied, and data should be transferred from the microprocessor while INH is held
low. When the data transfer has completed, set INH high. This will prevent meaningless displays at power on.
