DATA SHEET
MOS INTEGRATED CIRCUIT
µPD16449
SOURCE DRIVER FOR 240-OUTPUT TFT-LCD
(NAVIGATION, AUTOMOBILE LCD-TV)
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.
In addition, simultaneous sampling and successive sampling are automatically selected according to the pixel
array of the LCD panel. It is ideal for a wide range of applications, including navigation systems and automobile
LCD-TVs.
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
• Left and right shift selected by R,/L pin
• TCP/COG mounting possible
5 Remark /xxx indicates active low signal.
