DATA SHEET MOS INTEGRATED CIRCUIT µ PD16640C 300/309-OUTPUT TFT-LCD SOURCE DRIVER (64 GRAY SCALE) DESCRIPTION The µ PD16640C is a source driver for TFT-LCD 64-gray scale displays. Its logic circuit operates at 3.3 V and the driver circuit operates at 3.3 or 5.0 V (selectable). The input data is digital data at 6 bits x 3 dots, and 260,000 colors can be displayed in 64-value outputs γ-corrected by the internal D/A converter and 11 external power supplies. The clock frequency is 55 MHz MIN. By switching over the number of outputs between 300 and 309, the µ PD16640C can be used in TFT-LCD panels conforming to the SVGA/XGA standards. Features - CMOS level input - Number of outputs selectable (Osel = H : 300 outputs, Osel = L : 309 outputs) - 6 bits (gray scale data) x 3 dots input - 64-value output by 11 external power supplies and internal D/A converter - Output dynamic range : VSS2 + 0.1 V to VDD2 - 0.1 V - High-speed data transfer: f MAX.=55 MHz MIN.(internal data transfer speed when VDD1 = 3.0 V) - Precharge-less output buffer - Level of γ-corrected power supply can be inverted. - Input data inversion function (INV) - Logic power supply (VDD1) : 3.3 V ± 0.3 V - Driver power supply (VDD2) : 3.3 V ± 0.3 V (Vsel = H) 5.0 V ± 0.5 V (Vsel = L) ORDERING INFORMATION Part Number Package TCP (TAB package) µ PD16640CN-xxx Remark The TCP’s external shape is customized.
