Quick Detail:

Universal LCD driver for low multiplex rates

Description:

The PCF8576D is a peripheral device which interfaces to
almost any Liquid Crystal Display (LCD) with low multiplex
rates. It generates the drive signals for any static or
multiplexed LCD containing up to four backplanes and up
to 40 segments and can easily be cascaded for larger LCD
applications. The PCF8576D is compatible with most
microprocessors/microcontrollers and communicates via a
two-line bidirectional I2
C-bus. Communication overheads
are minimized by a display RAM with auto-incremental
addressing, by hardware subaddressing and by display
memory switching (static and duplex drive modes).


Applications:

• Single-chip LCD controller/driver
• Selectable backplane drive configuration: static or 2/3/4
backplane multiplexing
• Selectable display bias configuration: static, 1/2 and 1/3
• Internal LCD bias generation with voltage-followerbuffers
• 40 segment drives: up to twenty 8-segment numeric
characters; up to ten 15-segment alphanumeric
characters; or any graphics of up to 160 elements
• 40 × 4-bit RAM for display data storage
• Auto-incremental display data loading across device
subaddress boundaries
• Display memory bank switching in static and duplex
drive modes
• Versatile blinking modes
• Independent supplies possible for LCD and logic
voltages
• Wide power supply range: from 1.8 to 5.5 V
• Wide logic LCD supply range: from
