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.
