Notes: 1. If the LSI is used above these absolute maximum ratings, it may become permanently
damaged. Using the LSI within the following electrical characteristics limits is strongly
recommended for normal operation. If these electrical characteristic conditions are also exceeded,
the LSI will malfunction and cause poor reliability.
2. VCC > GND must be maintained.
3. VLCD > GND must be maintained.
4. For bare die and wafer products, specified up to 85.
5. This temperature specifications apply to the TCP package.

Description

The HD66740, 112-by-80 dot-matrix graphics LCD controller and driver LSI, displays graphics such as text, kanji and pictograms. It can be configured to drive a dot-matrix liquid crystal under the control of the microprocessor connected via the clock-synchronized serial or 4/8-bit bus. The HD66740 has a smooth vertical scroll display and a double-height display for the remaining bit map areas. It fixed-displays a part of the graphics icons so that the user can easily see a variety of information.

The HD66740 has various functions to reduce the power consumption of an LCD system such as lowvoltage operation of 1.8 V min., a booster to generate maximum five-times LCD drive voltage from the supplied voltage, and voltage-followers to decrease the direct current flow in the LCD drive bleederresistors.

Combining these hardware functions with software functions such as standby and sleep modes allows fine power control. The HD66740 is suitable for any portable battery-driven product requiring long-term driving capabilities such as cellular phones, pagers, or electronic wallets.
