Package: FP-80B, TFP-80F Type

Manufacturer: Hitachi -> Renesas Electronics


HCD44780U datasheet



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.


• 5 × 8 and 5 × 10 dot matrix possible

• Low power operation support :  2.7 to 5.5V

• Wide range of liquid crystal display driver power : 3.0 to 11V

• Liquid crystal drive waveform : A (One line frequency AC waveform)
