DATA SHEET MOS INTEGRATED CIRCUIT µPD16635 240-OUTPUT TFT-LCD SOURCE DRIVER (PATIBLE WITH 64 GRAY SCALES) The µPD16635 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 11.5 VP-P, level inversion operation of the LCD’s mon electrode is rendered unnecessary. Also, to be able to deal with full-dot 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 33 MHz when driving at 3.0 V, this driver is applicable to SVGA-standard TFT-LCD panels. Features - Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter - Output dynamic range 11.5 VP-P min. (@ VDD2 = 13.5 V) - CMOS level input - Input of 6 bits (gradation data) by 6 dots - High-speed data transfer: fmax. = 33 MHz (internal data transfer speed when operating at 3.0 V) - 240 outputs - Dedicaded full-dot inversion driver - Single-sided mounting possible (loaded with slim TCP) ORDERING INFORMATION Part Number Package TCP (TAB package) µPD16635N-××× The TCP’s external shape is customized.
