HD66705U
(Low-Power Dot-Matrix Liquid Crystal Display Controller/Driver)
ADE-207-305(Z)
'99.9
Rev. 0.0
Description
The HD66705U dot-matrix liquid crystal display controller and driver LSI displays alphanumerics,
katakana, hiragana, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the
control of a clock-synchronized serial, or a 4- or 8-bit microprocessor. A single HD66705U is capable of
displaying a maximum of two 12-character lines, 40 segments, and 10 annunciators. The HD66705U
incorporates all the functions required for driving a dot-matrix liquid crystal display such as display RAM,
character generator, and liquid crystal drivers, and a booster for LCD power supply.
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.
