SOURCE DRIVER FOR 240-OUTPUT TFT-LCD (64 GRAY SCALES)

DESCRIPTION

The µPD16641 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 × 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.

Because the clock frequency is 33 MHzMIN, the µPD16641 can be used in TFT-LCD panels conforming to the VGA

standards.

FEATURES

• Precharge-less output buffer

• 64-value output by 11 external power supplies and internal D/A converter

• Level of γ-corrected power supply can be inverted

• Output voltage range: 2.8 VP-PMAX. (at supply voltage VDD2 of driver circuit = 3.0 V)

4.3 VP-PMAX. (at supply voltage VDD2 of driver circuit = 4.5 V)

• CMOS level input

• 6 bit (gray scale data) × 3 dot input

• High-speed data transfer: fmax. = 33 MHzMIN. (internal data transfer rate at supply voltage VDD1 of logic circuit = 3.0 V)

• 240 outputs

• Supply voltage of driver circuit selectable (Vsel = H: 3.3 V, Vsel = L: 5.0 V)

• Slim TCP
