1998 el Pr y ar in im GENERAL DESCRIPTION The ML9090-01 and ML9090-02 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 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 ¥ 16 dots (80 ¥ 8 dots for the ML9090-01, 80 ¥ 16 dots for the ML9090-02) and an arbitrator display system of 80 ¥ 2 dots.
Since containing voltage multipliers, the ML9090-01 and ML9090-02 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.
FEATURES • Logic voltage: VDD 2.
