Description
GSM7980
The GSM7980 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- 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. The GSM7980 has pin function compatibility with the HD44780, KS0066U and SED1278 that allows the user to easily replace it with an GSM7980.
