Low-power Dot-matrix Liquid Crystal Display Controller/driver With Key Scan Function

The HD66727 dot-matrix liquid crystal Display controller and driver LSI incorporating a key scan function, Displays alphanumerics, katakana, hiragana, and symbols. It CAN be configured to drive a dot- matrix liquid crystal Display and control key scan functions under the control of an I 2 C bus or a clock- synchronized serial Microprocessor 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 incorporates all the functions required for driving a dot-matrix liquid crystal Display such as Display RAM, character generator, and liquid crystal drivers, and it also incorporates a booster for the LCD power supply and key scan functions. The HD66727 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 HD66727 with the above functions, is suitable for any portable battery- driven product requiring long-term driving capabilities and small size. By Renesas Technology
