HD66762
(128 x 136-dot Graphics LCD Controller/Driver for 256 Colors)
Rev 1.0
October.
2001
Description
The HD66762, color-graphics LCD controller and driver LSI, displays 128-by-136-dot graphics for
256 STN colors. The HD66762's bit-operation functions and a 16-bit high-speed
bus interface enable efficient data transfer and high-speed rewriting of data to the graphics RAM.
The HD66762 has various functions for reducing the power consumption of an LCD system, such
as low-voltage operation of 1.8 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 HD66762 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.
