GENERAL DESCRIPTION
This version: Nov. 1997
MSM6660-01,02,03
Previous version: Mar. 1996
1/2, 1/3 DUTY LCD DRIVER WITH 3-DOT COMMON DRIVER AND 62-DOT SEGMENT
DRIVER
The MSM6660 is a dynamic display LCD driver, equipped with a function that can switch
between 1/2 and 1/3 duty. The MSM6660 can directly drive LCDs with up to 124 or 186
segments, depending on whether 1/2 or 1/3 duty is selected.
The MSM6660’s on-board display synchronization circuit allows display in a multi-chip
configuration.
