UPD16641 - SOURCE DRIVER

General 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).

Key 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.

DATA SHEET MOS INTEGRATED CIRCUIT µPD16641 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.
