DESCRIPTION The µPD160040 is a source driver for TFT-LCDs capable of dealing with displays with 256-gray scales. Data input is based on digital input configured as 8 bits by 6 dots (2 pixels), which can realize a full-color display of 16,777,216 colors by output of 256 values γ -corrected by an internal D/A converter and 8-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 8-bit D/A converter circuit whose odd output pins and even output pins respectively output gray scale voltages of differing polarity. FEATURES • CMOS level input • 384 outputs • Input of 8 bits (gray scale data) by 6 dots • Capable of outputting 256 values by means of 8-by-2 external power modules (16 units) and a D/A converter • Logic power supply voltage (VDD1): 2.5 to 3.6 V • Driver power supply voltage (VDD2): 12.5 to 15.5 V (switchable, VSEL) • Output dynamic range: VSS2 + 0.2 V to VDD2 – 0.2 V • High-speed data transfer: fCLK. = 55 MHz MAX. (internal data transfer speed when operating at 3.0 V ≤ VDD1 ≤ 3.6 V) fCLK. = 40 MHz MAX. (internal data transfer speed when operating at 2.5 V ≤ VDD1 < 3.0 V) • Apply for dot-line inversion, n-line inversion and column line inversion • Output voltage polarity inversion function (POL) • Output inversion function (POL21, POL 22) • Output reset control is possible (MODE) • Through-rate control is possible (SRC) • Output resistance control is possible (ORC) • Single bank arrangement is possible (loaded with slim TCP)
