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 I
are minimized by a display RAM with auto-incremental
addressing, by hardware subaddressing and by display
memory switching (static and duplex drive modes).
Compatible with 4, 8 or 16-bit microprocessors or
microcontrollers
May be cascaded for large LCD applications (up to
2560 elements possible)
No external components
Compatible with chip-on-glass technology
Manufactured in silicon gate CMOS process.
