Features: • Logic voltage : 4.5 to 5.5 V
• LCD drive voltage : 4.5 to 16.5 V (positive voltage)
• Segment output : 56 outputs for ML9092-01; 60 outputs for ML9092-02/03/04
• Common output : 10 outputs
• Built-in bit-mapped RAM : 60 * 10 = 600 bits (for ML9092-01 only: 56 * 10 = 560 bits for the RAM
display area)
• 4-pin serial interface with CPU: CS, CP, DI/O, KREQ
• Built-in LCD drive bias resistors
• Built-in voltage doubler circuit
• For the ML9092-01/04, the built-in 5 * 5 key scanner makes it possible to read the status of 25 key switches and
1-channel rotary encoder. In addition, the ML9092-01/04 have an 8-bit, 3-channlel PWM circuit built in.
For the ML9092-02/03, the built-in 6 * 4 key scanner makes it possible to read the status of 24 key switches and
1-channel rotary encoder.
• Port A output : 1 pin, output current = 15 mA : Can be used for LED driving
• Port B output : 3 pins, output current = 2 mA : Applies to ML9092-01/04 (capable of PWM
output)
• Port C output : 5 pin, output current = 2 mA : Applies to ML9092-01 only
• Port D output : 5 pins, output current = 2 mA : Applies to ML9092-01 only
• Temperature range : 40 to +85°C
• Package: 100-pin plastic TQFP (TQFP100-P-1414-0.50-K)

DescriptionThe ML9092-01/02/03/04 are LCD drivers that have internal RAM and a key scan function. They are best suited for car audio displays.
Since 1-bit data of the display data RAM of ML9092-01 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 graphic display system of a maximum of 60 × 10 dots (56 × 10 dots for ML9092-01, 60 × 10 dots for ML9092-02/03/04). can be implemented.
The ML9092-01/02 do not require any power supply circuit to drive the LCD, because they have internal voltage doublers. (If a large-sized panel is driven, use the ML9092-03, to which the LCD driving voltage is supplied
externally.)
The internal key scan circuit (5 × 5 key scanning for ML9092-01/04, 6 × 4 key scanning for ML9092-02/03) has eliminated the needs of key scanning by the CPU, thereby enabling the efficient use of the CPU ports.
