1/2, 1/3 DUTY LCD DRIVER WITH 3-DOT COMMON DRIVER AND 62-DOT SEGMENT
DRIVER
GENERAL DESCRIPTION
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.
FEATURES
• Power supply voltage : 4 to 6 V (for both logic and LCD driver)
• Operating temperature : –40˚C to +85˚C
• Applicable LCD duty : 1/2 (1/2 bias), 1/3 (1/3 bias)
• Common output
: 2 (1/2 duty), 3 (1/3 duty)
• Segment output
: 62
• Serial transfer clock rate : 2 MHz Maximum
• On-board display synchronization circuit which enables display in a multi-chip configuration.
• CE, DATA, and CK are provided for microcomputer interface.
• Handling of display data segments in three blocks enables efficient data transfer.
• Equipped with display-blanking input and display segment test input functions.
• A built-in voltage dividing resistor for bias voltage generation.
- 01: No internal resistance
- 02: 1 kΩ internal resistance
