HD66766 Rev. 1.0 / 30 November 2001 HD66766 (132 x 176-dot Graphics LCD Controller/Driver for 65K Colors) Rev.1.0 November, 2001 Description The HD66766, color-graphics LCD controller and driver LSI, displays 132-by-176-dot graphics for 65K STN colors. A 16-bit high-speed bus interface and high-speed RAM write function enable efficient data transfer and high-speed rewriting of data to the graphics RAM. The HD66766 has various functions for reducing the power consumption of a LCD system, such as lowvoltage operation of 2.2 V/min., a step-up circuit to generate a maximum of 12-times the LCD drive voltage from the supplied voltage, and voltage-followers to decrease the direct current flow in the LCD drive bleeder-resistors.
