Description
The ST7066 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 ST7066 has pin function compatibility with the
HD44780, KS0066U and SED1278 that allows the
user to easily replace it with an ST7066. The ST7066
character generator ROM is extended to generate
208 5 x 8 dot character fonts and 32 5 x 10 dot
character fonts for a total of 240 different character
fonts. The low power supply (2.7V to 5.5V) of the
ST7066 is suitable for any portable battery-driven
product requiring low power dissipation.
The ST7066 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 ST7066 can
display up to one 8-character line or two 8-character
lines.
