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: fMAX.=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)
