HD66729  
HD66729  
(Low-power 105 x 68-dot Graphics LCD Controller/Driver)  
Preliminary  
Rev 0.4a  
June 25, 1999  
Description  
The HD66729, 105-by-68 dot-matrix graphics LCD controller and driver LSI, displays graphics. It can be  
configured to drive a dot-matrix liquid-crystal display under the control of a microprocessorconnectedvia  
a clock-synchronized serial or 4/8-bit bus. The HD66729 has a partial display mode thatselectsand drives  
part of the display area by using a low-duty ratio, a centering display mode that places the LCD drive  
position at the center of the screen, a smooth vertical-scrolldisplaymode and a double-heightdisplaymode  
for the remaining bit-map areas. It continuously displays several of the graphics icons so that the usercan  
easily access a variety of information.  
The HD66729 has a booster to generate a quintuple LCD drive voltage from a single 1.8-V power supply  
and voltage-followers to decrease the direct current flow in the LCD drive bleeder resistors. Combining  
these hardware functions with software functions such as standby and sleep, enables fine power control.  
The HD66729 is suitable for any portable battery-driven product requiring long-term driving capabilities,  
including cellular phones, pagers, and electronic wallets.
