HD66753
(168 x 132-dot Graphics LCD Controller/Driver with
Bit-operation Functions)
ADE-207-347(Z)
Rev. 1.0
Jan. 31. 2003
Description
The HD66753, dot-matrix graphics LCD controller and driver LSI, displays 168-by-132-dot graphics for
four monochrome grayscales. When 12-by-13-dot size fonts are used, up to 13 lines
x
11 characters (143
characters) can be simultaneously displayed. Since the HD66753 incorporates bit-operation functions and a
16-bit high-speed bus interface, it enables efficient data transfer and high-speed rewriting of data in the
graphics RAM.
The HD66753 has various functions for reducing the power consumption of an LCD system, such as low-
voltage operation of 1.7 V/min., a step-up circuit to generate a maximum of seven-times the LCD drive
voltage from the input-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 a
partial display with low-duty drive and standby and sleep modes, allows precise power control. The
HD66753 is suitable for any mid-sized or small portable battery-driven product requiring long-term driving
capabilities, such as digital cellular phones supporting a WWW browser.

Note: When a three-, five-, six-, or seven-times step-up is used:
the total current consumption = internal logic current + LCD power current x 3 (three-times step-up),
the total current consumption = internal logic current + LCD power current x 5 (five-times step-up),
the total current consumption = internal logic current + LCD power current x 6 (six-times step-up),
and
the total current consumption = internal logic current + LCD power current x 7 (seven-times step-up)
