LC75850E, 75850W
1/3 Duty General Purpose LCD Drivers
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 un-
conditionally.
• 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 with-
out 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.

Function
Segment outputs that display the data transferred as serial data
Common driver outputs. The frame frequency is fO=(fOSC/384)Hz.
Oscillator connection
(for generating the common segment alternation waveform)
Serial data transfer pins : connected to the
microprocessor.
CE: chip enable
CL: synchronization clock
DI: transfer data
Forcibly turns off the display without regard for the internal data.
Serial data can always be input, whatever the state of this pin.
Used for the 2/3 bias voltage when bias voltages are provided externally.
Connect to VDD2 when 1/2 bias is used.
Used for the 1/3 bias voltage when bias voltages are provided externally.
Connect to VDD1 when 1/2 bias is used.
