UPD160040A - 384-OUTPUT TFT-LCD SOURCE DRIVER

General Description

The µPD160040A is a source driver for TFT-LCDs capable of dealing with displays with 256-gray scales.

Key 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).
  • High-speed data transfer: fCLK = 55 MHz MAX. (internal data transfer speed when operating at 3.0 V ≤ VDD1 ≤ 3.6 V) = 40 MHz MAX. (int.

DATA SHEET www.DataSheet4U.com MOS INTEGRATED CIRCUIT µPD160040A 384-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 256-GRAY SCALES) DESCRIPTION The µPD160040A 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.
