DESCRIPTION
A single HD66705U is capable of displaying a maximum of two 12-character lines, 40 segments, and 10 annunciators. The HD66705U provides various functions to reduce the power consumption of an LCD system such as low-voltage operation of 2.4V or less, a booster for generating a maximum of triple LCD drive voltage from the supplied voltage, and voltage-followers for decreasing the direct current flow in the LCD drive bleeder-resistors. Combining these hardware functions with software functions such as standby and sleep modes allows a fine power control. The HD66705U, with the above functions, is suitable for any portable battery-driven product requiring long-term driving capabilities and small size.FEATURES
