Rev.1.1 / April 2002 396-channel Source Driver with Internal RAM for TFT 65536-color Displays Rev.1.1 m April 2002 .co Description 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 bination 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. he The 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,...
