Description

The ST7066U 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-or8-bit microprocessor. Since all the functions such as display RAM, character generator, and liquid crystal driver, required fordriving a dot- matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver.

Features
