UPD16640C - 300/309-OUTPUT TFT-LCD SOURCE DRIVER

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).

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 supp.

DATA SHEET MOS INTEGRATED CIRCUIT µ PD16640C 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.
