DESCRIPTION
A single HD66726 is capable of displaying up to five 16-character lines, 96-by-40 dot graphics and 192 segments. Of the 192 segments displayed, 64 segments can be grayscaled. The HD66726 has various functions to reduce the power consumption of an LCD system such as lowvoltage operation of 2.2 V or less, a booster to generate maximum quadruple 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 HD66726 is suitable for any portable battery-driven product requiring longterm driving capabilities and small physical dimensions such as cellular phones, pagers, portable audio devices, or electronic wallets.45FEATURES
