HD66702 Description
The HD66702 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 required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this...
