MSM9004-01/02
1/3, 1/4 DUTY LCD DRIVER WITH 4-DOT COMMON DRIVER AND 49-DOT SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM 9004-01/02 is an LCD driver for dynamic display with a 1/3 or 1/4 duty select function.
When the 1/3 duty is selected, it can display up to 147 segments, and when the 1/4 duty is
selected, up to 196 segments.
FEATURES
• Logic power supply voltage (VDD)
• LCD drive power supply voltage (VLCD)
• Serial transfer clock frequency
• LCD output resistance

The select bits C1 to C4 select Data latch 1 to Data latch 4 corresponding to COM 1 to COM 4
independently. If logic "1s" are selected to multiple select bits, the LCD display bits are written
to all corresponding data latches.
Example:
When logic "1s" are set to all select bits C1 to C4, and logic "0s" are set to all LCD display bits D1
to D49, logic "0s" are written to Data latch 1 to Data latch 4 by one data input. This leads to turning
off the entire LCD panel.
