The ML9090A-01 and ML9090A-02 are LCD drivers that contain internal RAM and a key scan function. They are best suited for car audio displays. Since 1-bit data of the display data RAM corresponds to the light-on or light-off of 1-dot of the LCD panel (a bit map system), a flexible display is possible. A single chip can implement a graphic display system of a maximum of 80 × 18 dots (80 × 10 dots for the ML9090A-01, 80 × 18 dots for the ML9090A-02). Since containing voltage multipliers, the ML9090A-01 and ML9090A-02 require no power supply circuit to drive the LCD. Since the internal 5 × 5 scan circuit has eliminated the needs of key scanning by the CPU, the ports of the CPU can be efficiently used.
