DATA SHEET MOS INTEGRATED CIRCUIT µ PD16641 240-OUTPUT TFT-LCD SOURCE DRIVER (64-GRAY SCALES) DESCRIPTION The µ PD16641 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 33 MHz, and the µ PD16641 can be used in TFT-LCD panels conforming to the VGA standards. Features - CMOS level input - 240 outputs - 6 bits (gray scale data) x 3 dots input - 64-value output by 11 external power supplies and internal D/A converter - High-speed data transfer: f CLK = 33 MHz MAX. (internal data transfer speed when VDD1 = 3.0 V) - Pre-charge-less output buffer - Level of γ -corrected power supply can be inverted. - Driver power supply voltage selectable is possible (Vsel = H: 3.3 V, Vsel = L: 5.0 V) - Output voltage range: 2.8 VP-P MAX. (driver power supply voltage VDD2 = 3.0) 4.3 VP-P MAX. (driver power supply voltage VDD2 = 4.5) - Loaded with slim TCP ORDERING INFORMATION Part Number µ PD16641N-xxx Package TCP (TAB package) Remark The TCP’s external shape is customized.
