S6C1652 6 BIT 300 / 309 CHANNEL TFT-LCD SOURCE DRIVER
INTRODUCTION
The S6C1652 is a 300 / 309 channel output, TFT-LCD source driver for an 64 gray-scale LCD panel. Data input
is based on digital input consisting of 6 bits by 3 dots, which can realize a full-color display of 260,000 color by
output of 64 values gamma-corrected.
This device has an internal D/A (digital-to-analog) converter for each output and 18 (9-by-2) reference voltages.
Because the output dynamic range is as large as 6.0 - 12.6 Vp-p, it is unnecessary to operate level inversion of
the LCD's common electrode. Besides, to be able to deal with dot-line inversion when mounted on a single-side,
output gray-scale voltages with different polarity can be output to the odd number output pins and the even output
pins.
S6C1652 can be adopted to larger panel, and SHL (shift direction selection) pin makes the use of the LCD panel
connection conveniently. Maximum operation clock frequency is 55 MHz at 2.7 V logic operation, single edge
and it can be applied to the TFT-LCD panel of SVGA to XGA standard.
FEATURES
• TFT active matrix LCD source driver LSI
• 64 gray-scale is possible through 18 (9-by-2) reference voltages and D/A converter
• Dot inversion display is possible
• CMOS level input
• Compatible with gamma-correction
• Input of 6bits (gray-scale data) by 3 dots (R,G,B)
• Logic supply voltage: 2.7 - 3.6 V
• LCD driver supply voltage: 6.4 - 13.0 V
• Output dynamic range: 6.0 - 12.6 Vp-p
• Maximum operating frequency: fMAX = 55 MHz (internal data transmission rate at 2.7 V operation)
• Output: 300 / 309 outputs
• TCP available
