Summary:
Universal LCD driver for low multiplex rates
The OM4068 is a low-power CMOS LCD driver, designed to drive Liquid Crystal Displays (LCDs) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to three backplanes and up to 32 segment lines and can be easily cascaded for larger LCD applications. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD bias voltages, resulting in a minimum of external components and lower power consumption. A 3-line bus structure enables serial data transfer with most microprocessors/microcontrollers. All inputs are CMOS compatible.

Features and benefits

  • Single-chip LCD controller/driver
  • Static/duplex/triplex drive modes with up to 32/64/96 LCD segments drive capability per device
  • Selectable backplane drive configuration: static or 2 or 3 backplane multiplexing
  • Selectable display bias configuration drive: static, 1/2 or 1/3
  • 32 segment drivers
  • Serial data input (word length 32 to 96 bits)
  • On-chip generation of intermediate LCD bias voltages
  • 2 MHz fast serial bus interface
  • CMOS compatible
  • Compatible with any 4-bit, 8-bit or 16-bit microprocessors/microcontrollers
  • May be cascaded for large LCD applications
  • Logic supply voltage range (VDD - VSS ) of 2.5 to 5.5 V
  • Display supply voltage range (VLCD - VSS ) of 3.5 to 6.5 V
  • Low power consumption, suitable for battery operated systems
  • No external components needed by the oscillator
  • Manufactured in silicon gate CMOS process.

Applications

  • Telecom equipment
  • Portable instruments
  • Alarm systems
  • Automotive equipment.
