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)
