MSM5299A
80-DOT LCD SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM5299A is a dot matrix LCD segment driver LSI which is fabricated using CMOS low
power metal gate technology. This LSI consists of an 80-bit bidirectional shift register, 80-bit
latch, 80-bit level shifter and 80-bit 4-level driver.
It receives the display data, which is transferred in 4-bit parallel from a microcomputer or LCD
controller LSI such as MSM6255, then outputs the LCD driving waveform to the LCD.
FEATURES
• Supply voltage : 4.5 to 5.5V
• LCD driving voltage : 8 to 28V
• Applicable LCD duty : 1/64 to 1/256
• LCD Output : 80
• The 4-bit parallel data processing has improved the transfer speed to 1/4 that of the
conventional serial transfer, thereby achieving low power consumption
• Can be interfaced with the LCD controller LSI MSM6255
• Applicable common diriver : MSM5298A (68 outputs)
• Package options:
100-pin plastic QFP (QFP100-P-1420-0.65-K) (Product name : MSM5299AGS-K)
100-pin plastic QFP (QFP100-P-1420-0.65-BK) (Product name : MSM5299AGS-BK)
