HD66724/HD66725
(Graphics LCD Controller/Driver
with Key Scan Function)
ADE-207-309(Z)
Rev 1.2
'99.8
Description
The HD66724/HD66725, dot-matrix graphics LCD controller and driver LSI incorporating a key scan
function up to a 4-by-8 key matrix, display characters such as alphanumerics, katakana, hiragana and
symbols as well as graphics such as kanji and pictograms. They 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. The HD66724 is capable of displaying up to three 12-
character lines, 72-by-24 dot graphics and 144 segments. The HD66725 is capable of displaying up to
three 16-character lines, 96-by-24 dot graphics and 192 segments. Of the 144 (192) segments displayed, 48
(64) segments can be grayscaled. The HD66724/HD66725 have a smooth horizontal/vertical scroll display
and double-height display so that the user can easily see a variety of information within a small LCM.
The HD66724/HD66725 have various functions to reduce the power consumption of an LCD system such
as low-voltage operation of 1.8 V or less, a booster to generate maximum triple 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 HD66724/HD66725 are 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.

Note : When duty ratio = 1/2 and a double booster is not used:
the total power consumption = Internal logic current + LCD power current
When duty ratio = 1/10 and a double booster is used:
the total power consumption = Internal logic current + LCD power current x 2
