GENERAL DESCRIPTION
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).

FEATURES
• Logic voltage: 2.7 to 5.5 V
• LCD drive voltage: 6 to 16 V (positive voltage)
• 80 segment outputs, 10 common outputs for ML9090A-01 and 18 common outputs for ML9090A-02
• Built-in bit-mapped RAM (ML9090A-01: 80 × 10 = 800 bits, ML9090A-02: 80 × 18 = 1440 bits)
• 4-pin serial interface with CPU: CS, CP, DI/O, KREQ
• Built-in LCD drive bias resistors
• Built-in voltage doubler or tripler circuit
• Built-in 5 × 5 key scanner
• Port A output : 1 pin, output current: –15 mA: (may be used for LED driving)
• Port B output : 8 pins
    Output current (available for the ML9090A-01 only)
        –2 mA : 5 pins
        –15 mA : 3 pins
• Temperature range: –40 to +85°C
• Package: 128-pin plastic QFP (QFP128-P-1420-0.50-K)
