UPD16449 Datasheet Source Driver

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD16449 SOURCE DRIVER FOR 240-OUTPUT TFT-LCD (NAVIGATION, AUTOMOBILE.

General Description

µPD16449 is a source driver for TFT liquid crystal panels.

This IC consists of a multiplexer circuit supporting a ..variety of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample analog voltages.

Because the two sample and hold circuits alternately execute sampling and holding, a high definition can be obtained.

Key Features

  • Can be driven on 5 V (Dynamic range: 4.3 V, VDD2 = 5.0 V).
  • 240-output.
  • fCLK = 15 MHz MAX. (VDD1 = 3.0 V).
  • Simultaneous/successive sampling selectable according to pixel array Simultaneous sampling: Vertical stripe Successive sampling: Delta array, mosaic array.
  • Two sample and hold circuits.
  • Low output deviation between pins (± 20 mV MAX. ).
  • Stripe, delta, and mosaic pixel arrays supported by internal multiplexer circuit.
  • Lef.
