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.
