n Description
The ST7066U dot-matrix liquid crystal display
controller and driver LSI displays alphanumeric,
Japanese kana characters, and symbols. It can be
configured to drive a dot-matrix liquid crystal display
under the control of a 4- or 8-bit microprocessor.
Since all the functions such as display RAM,
character generator, and liquid crystal driver, required
for driving a dot-matrix liquid crystal display are
internally provided on one chip, a minimal system can
be interfaced with this controller/driver.
The ST7066U character generator ROM is extended
to generate 240 5x8(5x11) dot character fonts for a
l 16-common x 40-segment liquid crystal
display driver
l Programmable duty cycles
-- 1/8 for one line of 5 x 8 dots with cursor
-- 1/11 for one line of 5 x 11 dots & cursor
-- 1/16 for two lines of 5 x 8 dots & cursor
l Wide range of instruction functions:
Display clear, cursor home, display on/off,
cursor on/off, display character blink, cursor
shift, display shift
l Automatic reset circuit that initializes the
controller/driver after power on
l Internal oscillator with external resistors
l Low power consumption
l QFP80 and Bare Chip available
total of 240 different character fonts. The low power
supply (2.7V to 5.5V) of the ST7066U is suitable for
any portable battery-driven product requiring low
power dissipation.
The ST7066U LCD driver consists of 16 common
signal drivers and 40 segment signal drivers which
can extend display size by cascading segment driver
ST7065 or ST7063. The maximum display size can
be either 80 characters in 1-line display or 40
characters in 2-line display. A single ST7066U can
display up to one 8-character line or two 8-character
