DATA SHEET

300/309-OUTPUT TFT-LCD SOURCE DRIVER (64-GRAY SCALE)

The mark 5 shows major revised points.

The

µ PD16640B 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.

The clock frequency is 55 MHz MIN.

By switching over the number of outputs between 300 and 309, the

µ PD16640B can be used in TFT-LCD panels conforming to the SVGA/XGA standards.
