Description

The HD44780U dot-matrix liquid crystal display controller and driver LSI 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

The low power supply (2.7V to 5.5V) of the HD44780U is suitable for any portable battery-driven

product requiring low power dissipation.
