(graphics Lcd Controller/driver With Key Scan Function)

The HD66724 HD66725 dot-matrix graphics LCD Controller and driver LSI incorporating a key scan function up to a 4-by-8 key matrix, Display characters such as alphanumerics, katakana, hiragana and symbols as well as graphics such as kanji and pictograms. They CAN be configured to drive a dot-matrix liquid crystal Display and control key scan functions under the control of the Microprocessor connected via the clock-synchronized serial or 4/8-bit bus. The HD66724 is capable of displaying up to three 12- character lines, 72-by-24 dot graphics and 144 segments. The HD66725 is capable of displaying up to three 16-character lines, 96-by-24 dot graphics and 192 segments. Of the 144 (192) segments displayed, 48 (64) segments CAN be grayscaled. The HD66724 HD66725 have a smooth horizontal/vertical scroll Display and double-height Display so that the user CAN easily see a variety of information within a small LCM. The HD66724 HD66725 have various functions to reduce the power consumption of an LCD system such as low-voltage operation of 1.8 V or less, a booster to generate maximum triple 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 standby and sleep modes allows fine power control. The HD66724 HD66725 are suitable for any portable battery-driven product requiring long-term driving capabilities and small physical dimensions such as cellular phones, pagers, portable Audio devices, or electronic wallets.
