Product Summary
The HD44780A00 is a dot-matrix liquid crystal display controller and driver. It displays alphanumerics, Japanese kana characters, and symbols. The HD44780A00 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.
