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. The OM4085 is compatible with most
microprocessors/microcontrollers and communicates via a
two-line bidirectional I2C-bus. Communication overheads
are minimized by a display RAM with auto-incremented
addressing, by hardware subaddressing and by display
memory switching (static and duplex drive modes).
