ML9090-01,-02
LCD Driver with Key Scanner and RAM
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.
