ML9092-01/02/03/04

LCD Driver with Key Scanner and RAM

GENERAL DESCRIPTION

The 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 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.

FEATURES

• Logic voltage

: 4.5 to 5.5 V

• LCD drive voltage

• Segment output

: 4.5 to 16.5 V (positive voltage)

: 56 outputs for ML9092-01; 60 outputs for ML9092-02/03/04

• Common output

• Built-in bit-mapped RAM

: 10 outputs

: 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

• Port B output

: 1 pin, output current = –15 mA

: 3 pins, output current = –2 mA

: Can be used for LED driving

: Applies to ML9092-01/04 (capable of PWM

output)

• Port C output

• Port D output

• Temperature range

: 5 pin, output current = –2 mA

: 5 pins, output current = –2 mA

: –40 to +85°C

: Applies to ML9092-01 only

• Package: 100-pin plastic TQFP (TQFP100-P-1414-0.50-K)

(Product name: ML9092-01TB, ML9092-02TB, ML9092-03TB, ML9092-04TB)
