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.
