INTEGRATED CIRCUITS DATA SHEET OM4068 LCD driver for low multiplex rates 1998 Jun 18 Product specication File under Integrated Circuits, IC12Philips Semiconductors Product specication LCD driver for low multiplex rates OM4068 FEATURES APPLICATIONS Single-chip LCD controller/driver Telecom equipment Static/duplex/triplex drive modes with up to Portable instruments 32/64/96 LCD segments drive capability per device Alarm systems Selectable backplane drive configuration: static or Automotive equipment. 2 or 3 backplane multiplexing 1 Selectable display bias configuration drive: static, or 2 GENERAL DESCRIPTION 1 3 The OM4068 is a low-power CMOS LCD driver, designed 32 segment drivers to drive Liquid Crystal Displays (LCDs) with low multiplex Serial data input (word length 32 to 96 bits) rates. It generates the drive signals for any static or On-chip generation of intermediate LCD bias voltages multiplexed LCD containing up to three backplanes and up to 32 segment lines and can be easily cascaded for larger 2 MHz fast serial bus interface LCD applications. All necessary functions for the display CMOS compatible are provided in a single chip, including on-chip generation Compatible with any 4-bit, 8-bit or 16-bit of LCD bias voltages, resulting in a minimum of external microprocessors/microcontrollers components and lower power consumption. A 3-line bus structure enables serial data transfer with most May be cascaded for large LCD applications microprocessors/microcontrollers. All inputs are CMOS Logic supply voltage range (V - V ) of 2.5 to 5.5 V DD SS compatible. Display supply voltage range (V - V ) of LCD SS 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.
