DESCRIPTION
A single HD66727 is capable of displaying up to four 12-character lines, 40 segments, and 12 annunciators, and controlling up to a 4-by-8 key matrix, and driving three LED. The HD66727 provides various functions to reduce the power consumption of an LCD system such as lowvoltage 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 bleederresistors. Combining these hardware functions with software functions such as standby and sleep modes allows a fine power control. The HD66727, with the above functions, is suitable for any portable batterydriven product requiring long-term driving capabilities and small size.FEATURES
