ML9092-01 - LCD Driver

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.

Key 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.

LAPIS Semiconductor ML9092-01/02/03/04 LCD Driver with Key Scanner and RAM FEDL9092-01 Issue Date: Nov. 4, 2003 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.
