SC75823
1/3 DUTY GENERAL-PURPOSE LCD
DRIVER
DESCRIPTION
The SC75823 is a general-purpose LCD driver that can be used
for frequency display in microprocessor-controlled radio receives
and in other display applications. In addition to being able to directly
drive up to 156 LCD segments.
QFP-64-14x14-0.8
FEATURES
Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD
drive of up to 156 segments under serial data control.
Serial data input supports CCB format communication with the
system controller.
LQFP-64-10 x 10-0.5
Serial data control of the power-saving mode based backup
function and all the segments forced off function.
High generality since display data is displayed directly without ORDERING INFORMATION
decoder intervention.
Device
Package
The INH pin can force the display to the off state.
SC75823A LQFP-64-10 X 10-0.5
The LCD drive bias voltage can be provided internally or SC75823B QFP-64-14 X 14-0.8
externally.
Power supply voltage: 4.5 to 6.0V
