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 (VDD) Operating temperature (Top) LCD driving voltage (VDD-VLC3) · Segment output 1/5 duty 1/4 duty 1/3 duty · Serial transfer clock frequency · Serial interface with CPU 2.7 to 5.5V 40 to +85°C 3.5 to 5.5V 80 pins Up to 400 segments can be displayed. Up to 320 segments can be displayed. Up to 240 segments can be displayed. 4MHz 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) : : : : : : : : :
