Datasheet LCD 2 x16 (HD44780U)
DATASHEET LCD HD44780U dot-matrix liquid crystal display controller and driver LSI “LAPTOP” displays
alphanumerics, 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.
A single HD44780U can display up to one 8-character line or two 8-character lines.
The HD44780U has pin function compatibility with the HD44780S which allows the user to easily
replace an LCD-II with an HD44780U. The HD44780U character generator ROM is extended to
generate 208 5 ´ 8 dot character fonts and 32 5 ´ 10 dot character fonts for a total of 240
different character fonts. The low power supply (2.7V to 5.5V) of the HD44780U is suitable for
any portable battery-driven product equiring low power dissipation.
