GENERAL DESCRIPTION

The OM4085 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) having low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 24 segments and can easily be cascaded for larger LCD applications.

FEATURES

? Single-chip LCD controller/driver

? Selectable backplane drive configuration: static or 2, 3 or 4 backplane multiplexing

? Selectable display bias configuration: static, 1?2 or 1?3

? Internal LCD bias generation with voltage-follower buffers

? 24 segment drives: up to twelve 8-segment numeric characters; up to six 15-segment alphanumeric characters; or any graphics of up to 96 elements

? 24 × 4-bit RAM for display data storage

? Auto-incremented display data loading across device subaddress boundaries

? Display memory bank switching in static and duplex drive modes

? Versatile blinking modes

? LCD and logic supplies may be separated

? 2.0 to 6 V power supply range

? Low power consumption

? Power saving mode for extremely low power consumption in battery-operated and telephone applications

? I2C-bus interface

? TTL/CMOS compatible

? Compatible with any 4-bit, 8-bit or 16-bit microprocessors/microcontrollers

? May be cascaded for large LCD applications (up to 1536 segments possible)

? Cascadable with the 40 segment LCD driver PCF8576C

? Optimized pinning for single plane wiring in both single and multiple OM4085 applications

? Space-saving 40 lead plastic very small outline package (VSO40; SOT158-1)

? No external components required (even in multiple device applications)

? Manufactured in silicon gate CMOS process.
