ML9040-Bxx Overview
The ML9040-Axx/-Bxx is a dot matrix LCD controller which is fabricated in low power CMOS silicon gate technology. Character display on the dot matrix character type LCD can be controlled in bination with a 4-bit or 8-bit microcontroller. This LSI consists of 16-dot MON driver, 40-dot SEGMENT driver, display data RAM, character generator RAM, character generator ROM and control circuit.
