MSM5265
80-DOT LCD DRIVER
This version: Nov. 1997
MSM5265
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5265 is an LCD driver which can directly drive up to 80 segments in the static display
mode and up to 160 segments in the 1/2 duty dynamic display mode.
The MSM5265 is fabricated with low power CMOS metal gate technology. The MSM5265
consists of a 160-stage shift register, 160-bit data latch, 80 pairs of LCD drivers and a common
signal generator.
The display data is serially input from the DATA-IN pin to the 160-stage shift register synchronized
with the CLOCK pulse. The data is shifted into the 160-bit data latch by the LOAD signal. Then
the latched data is directly output to the LCD from the 80 pairs of LCD drivers as a serial output.
The common signal can be generated by the built-in generator, or externally input. The common
synchronization circuit which is used in the dynamic display mode is integrated on the chip.
