80-DOT LCD SEGMENT DRIVER
This version: MSM5299A Nov. 1997 Previous version: Mar. 1996
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)
