The PCF8577C is a single chip, silicon gate CMOS circuit.
It is designed to drive liquid crystal displays with up to
32 segments directly, or 64 segments in a duplex
configuration.
The two-line I2C-bus interface substantially reduces wiring
overheads in remote display applications. I2C-bus traffic is
minimized in multiple IC applications by automatic address
incrementing, hardware subaddressing and display
memory switching (direct drive mode).To allow partial VDD
shutdown the ESD protection system of the SCL and SDA
pins does not use a diode connected to VDD.
