396-channel Source Driver with Internal RAM for TFT 65536-color Displays
Rev.1.1
mApril 2002
.coDescription
UThe HD66770, 396-channel source driver LSI, displays 132RGB-by-176 dot graphics on TFT displays
t4in 65,536 colors. It is for driving TFT color LCD displays to a maximum of 132RGB by 176 dots, in
combination with the gate driver, HD66771 and Power supply IC, HD667P00. The HD66770’s bit-
eoperation functions, 16-bit high-speed bus interface, and high-speed RAM-write functions enable
efficient data transfer and high-speed rewriting of data to the graphics RAM.
heThe HD66770, HD66771 and HD667P00 have various functions for reducing the power consumption of
a LCD system. HD66770 has a low-voltage operation (1.8 V min.) and an internal RAM to display a
Smaximum of 132RGB-by-176 dot color, and the HD66771 has 288 pins of TFT gate wiring driver
circuit. Also, HD667P00 has the internal booster that generates the liquid crystal voltage, breeder
taresistance and the voltage follower circuit for liquid crystal driver. HD66770 incorporates a circuit that
interfaces with the HD66771/HD667P00, it can set instructions for HD66771/HD667P00. In addition,
aprecise power control can be achieved by combining these hardware functions with software functions,
such as an 8-color display and standby and sleep mode. This LSI is suitable for any medium-sized or
.Dsmall portable battery-driven product requiring long-term driving capabilities, such as digital cellular
phones supporting a WWW browser, bi-directional pagers, and small PDAs.
wFeatures
w• 132RGB x 176-dot graphics display LCD controller/driver for 65,536 TFT colors (when
wHD66771/HD667P00 are used)
• 16-/8-bit high-speed bus interface and serial peripheral interface (SPI)
• High-speed burst-RAM write function
• Writing to a window-RAM address area by using a window-address function
• Bit-operation functions for graphics processing:
• Write-data mask function in bit units
• Logical operation in pixel unit and conditional write function
• Various color-display control functions:
• 65,536 colors can be displayed at the same time (gamma adjust included)
• Vertical scroll display function in raster-row units

Functions
Output signals are for liquid crystal voltage. The SS bit
can change the shift direction of the source signal. For
example, if SS = 0, RAM address 0000 is output from S1.
If SS = 1, it is output from S396.
S1, S4, S7, ... display red (R), S2, S5, S8, ... display green
(G), and S3, S6, S9, ... display blue (B) (SS = 0).
The one-raster-row-cycle pulse is output.
The AC-cycle signal is output.
The frame-start pulse is output.
Indicate setting of the Vcom output to its high-impedance
state during transitions of Vcom when Vcom is being AC-
cycled.
Low: VcomH or VcomL is being output on the Vcom pin.
High: Vcom pin is in high-impedance state
Gate off signal in the partial display
“Low” : Output Voff signal
“High” : Output normal signal
Outputs clock for the step-up circuit of HD667P00.
Clock signal for a serial transfer of register setting values
to the gate driver and the power supply IC. Data is output
on the falling edge of this clock.
Data signal for serial transfer as register setting values to
the gate driver and The power supply IC.
Chip-select for the HD66771 and HD667P00.
Low: the HD66771/HD667P00 are selected and can
receive a serial transfer data.
High: the HD66771/HD667P00 are not selected and
cannot receive a serial transfer data.
Input power supply for LCD drive circuit, which can be
provided by HD667P00. DDVDH : +4.5 to +5.5 V
This is the standard level of grayscale voltage generator,
which can be provided by HD667P00. VDH (max.) :
DDVDH – 0.5 V
It is a signal for equalizing function. All LCD driver’s
outputs (S1 to S396) are short to Vcom level (Hi-Z) in EQ
= ”High” period. Must be left disconnected when VcomL
< 0 V.
VCC: + 1.8 V to + 3.6 V; GND (logic): 0 V
Connect an external resistor for R-C oscillation. When
input the clock from outside, input to OSC1, and open
OSC2.
Reset pin. Initializes the LSI when low. Must be reset after
power-on.
