80-dot Graphics LCD Controller/Driver for 256 Colors
ADE-207-335A(Z)
Rev.2.0
September 2001
Description
The HD66760, color-graphics LCD controller and driver LSI, displays 104-by-80-dot graphics for 256 STN
colors. The HD66760'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 HD66760 has various functions for reducing the power consumption of an LCD system, such as low-
voltage operation of 2.2 V/min., a step-up circuit to generate a maximum of six-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 HD66760 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, bidirectional pagers, and small PDAs.
