MSM6775
1/3, 1/4, 1/5 DUTY LCD DRIVER WITH 5-DOT COMMON DRIVER AND 80-DOT
SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM6775 is an LCD driver for dynamic display providing 3-duty-switchable pins (1/3, 1/
4 and 1/5 duty). It can directly drive LCDs of up to 400, 320 and 240 segments when 1/5, 1/4
and 1/3 duty are selected, respectively.
FEATURES
• Operating range
Supply voltage (V_DD)
Operating temperature (T_op)
LCD driving voltage (V_DD-V_LC3)
• Segment output
: 2.7 to 5.5V
: –40 to +85°C
: 3.5 to 5.5V
: 80 pins
1/5 duty
: Up to 400 segments can be displayed.
1/4 duty
: Up to 320 segments can be displayed.
1/3 duty
: Up to 240 segments can be displayed.
• Serial transfer clock frequency
: 4MHz
• Serial interface with CPU
: Through three input pins (DATA, LOAD, and
CLOCK)
• One-to-one corresponcence between input data and its output
When input data is at "H" level
: Display goes on.
When input data is at "L" level
: Display goes off.
• Built-in oscillator circuit for COMMON signals
• The entire display can be turned off. (BLANK pin)
• Package:
100-pin plastic TQFP (TQFP100-P-1414-0.50-K) (Product name : MSM6775TS-K)
