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
★ Remark /xxx indicates active low signal.

I/O
16 to 18
Start pulse I/O pins of sample hold timing. STHR serves as an input
pin and STHL, as an output pin, in the case of right shift. In the case of
left shift, STHL serves as an input pin, and STHR, as an output pin.
CLI1 to
Shift clock input
CLI3
34 to 38,
Input
A start pulse is read at the rising edge of CLI1. Sampling pulse SHPn
37 to 39,
is generated at the rising edge of CLI1 through CLI3 during successive
40 to 42
sampling, and at the rising edge of CLI1 during simultaneous sampling
(for details, refer to the Timing charts in 5. FUNCTIONAL
DESCRIPTION).
INH
Inhibit input
31 to 33
Input
Selects a multiplexer and one of the two sample and hold circuits at the
falling edge.
RESET
Reset input
28 to 30
Input
Resets the select counter of the multiplexer and the selector circuit of
the two sample and hold circuits when it goes high. After reset, the
multiplexer is turned OFF, so sure to input one pulse of the INH signal
before inputting the video signal. If the video signal is input without the
INH signal, sampling is not executed.

5. FUNCTIONAL DISCRIPTION
5.1 Multiplexer Circuit
This circuit selects RGB video signals input to the C1 to C3 pins according to the pixel array of the liquid crystal
panel, and outputs the signals to the H1 through H240 pins.
Vertical stripe array, single-/double-side delta array, or mosaic array can be selected by using the MP/TH and
MP/1.5 pins.
5.1.1 Vertical stripe array mode (MP/TH = L, MP/1.5 = L)
In this mode, the relation between video signals C1 to C3, and output pins is as shown below. This mode is used to
drive a panel of vertical stripe array. In this mode, the multiplexer circuit is in the through status.

Because the pad pitch of the µPD16449 is designed so that the IC is mounted on one side, the output pitch must be
expanded on the TCP if the IC is mounted on both sides.

The sample and hold circuit samples and holds the video input signals C1 through C3 selected by the multiplexer
circuit in the timing shown below. Swa1 through Swb2 are reset by the RESET signal and change at the rising and
falling edges of the INH signal (refer to 1. BLOCK DIAGRAM.).

5.3 Write Operation Timing
The sampled video signals are written to the LCD panel by output currents IVOL and IVOH via output buffer. The
dynamic range is 4.3 V MIN. (VDD2 = 5.0 V).
While INH = H, do not stop shift clocks CLI1 through CLI3.
The output operation of this IC is controlled by INH signals.
INH = Hi-Z
INH = Connected with internal circuit (switch sample and hold circuit at the falling edge.)
Therefore, performing VCOM inversion while INH = L causes current flow to these IC output pins, which may result
in malfunction. Perform VCOM in version during INH = H (Hi-Z) and start output operation of the next line after the VCOM
signal is stable enough to operate. Make sure to evaluate this output operation sufficiently.

Cautions 1. Turn on power to VDD1, logic input, VDD2, and video signal input in that order to prevent
destruction due to latch-up, and turn off power in the reverse sequence. Observe this power
sequence even during the transition period.
2.
The µPD16449 is designed to input successive signals such as chrome signals. The input band
of the video signals is designed to be 9 MHz MAX. If video signals faster than that are input,
display is not performed correctly.
3.
Insert a bypass capacitor of 0.1 µF between VDD1 and VSS1 and between VDD2 and VSS2. If the
power supply is not reinforced, the sampling voltage may be abnormal if the supply voltage
fluctuates.
4.
Display may not be correctly performed if noise is superimposed on the start pulse pin.
5.
Even if the start pulse width is extended by half a clock or more, sampling start timing SHP1 is

not affected, and the sampling operation is performed normally.
sampled at the rising edge of SHPn. Internally, however, only CLI1 is valid. Therefore, input a
shift clock to CLI1 only. At this time, keep the CLI2 and CLI3 pins to "L".
When using the multiplexer circuit in the delta array mode or mosaic array mode, C1 to C3 are
sequentially sampled. Input a three-phase clock to CLI1 through CLI3 (for the sampling timing,
refer to 5. FUNCTIONAL DESCRIPTION.).
7.
The recommended timing of tR-1 and PWRES on starting is shown below (The following timing
chart shows simultaneous sampling.).
An INH pulse width of at least 5 clocks is required to reset the internal logic. Unless the INH
pulse is input after reset, sampling is not performed in the correct sequence.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.
