HD66766R

(132 x 176-dot Graphics LCD Controller/Driver for 65K Colors)

Rev.1.0-1

September, 2002

Description

The HD66766R, 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 HD66766R has various functions for reducing the power consumption of a LCD system, such as

low-voltage 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. Combining these hardware functions with software functions, such as a partial

display with low-duty drive and standby and sleep modes, allows precise power control. The HD66766R

is suitable for any mid-sized or small portable battery-driven product requiring long-term driving

capabilities, such as digital cellular phones supporting a WWW browser, bi-directional pagers, and small

PDAs.

Features

132RGB x 176-dot graphics display LCD controller/driver for 65K STN colors
