HD66726
(Graphics LCD Controller/Driver
with Key Scan Function)
ADE-207-310(Z)
Rev 1.1
Aug, 1999
Description
The HD66726, dot-matrix graphics LCD controller and driver LSI incorporating a key scan function up to a
4-by-8 key matrix, displays characters such as alphanumerics, katakana, hiragana and symbols as well as
graphics such as kanji and pictograms. It can be configured to drive a dot-matrix liquid crystal display and
control key scan functions under the control of the microprocessor connected via the clock-synchronized
serial or 4/8-bit bus. 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 a smooth vertical scroll display and double-width display so that the user can easily see a variety of
information within a small LCM.
The HD66726 has various functions to reduce the power consumption of an LCD system such as low-
voltage 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 bleeder-
resistors. 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 long-
term driving capabilities and small physical dimensions such as cellular phones, pagers, portable audio
devices, or electronic wallets.45
