DATA SHEET MOS INTEGRATED CIRCUIT www.DataSheet4U.com µPD160061A 384-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES) DESCRIPTION The µPD160061A is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scales. Data input is based on digital input configured as 6 bits by 6 dots (2 pixels), which can realize a full-color display of 260,000 colors by output of 64 values γ -corrected by an internal D/A converter and 5-by-2 external power modules. Because the output dynamic range is as large as VSS2 + 0.2 V to VDD2 – 0.2 V, level inversion operation of the LCD’s common electrode is rendered unnecessary. Also, to be able to deal with dot-line inversion, n-line inversion and column line inversion when mounted on a single side, this source driver is equipped with a built-in 6-bit D/A converter circuit whose odd output pins and even output pins respectively output gray scale voltages of differing polarity. Assuring a maximum clock frequency of 65 MHz when driving at 2.7 V, this driver is applicable to XGA-standard TFT-LCD panels and SXGA TFT-LCD panels. FEATURES CMOS level input (2.3 to 3.6 V) 384 outputs Input of 6 bits (gray-scale data) by 6 dots Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter (R-DAC) Logic power supply voltage (VDD1): 2.3 to 3.6 V Driver power supply voltage (VDD2): 7.5 to 9.5 V High-speed data transfer: fCLK = 65 MHz MAX.
