I2C-Bus: What's that?
The I2C bus was designed by Philips in the early '80s to allow easy communication between components which reside on the same circuit board. Philips Semiconductors migrated to NXP in 2006.
The name I2C translates into "Inter IC". Sometimes the bus is called IIC or I²C bus. ...

    Sehr einfache Ansteuerung per I2C Bus
    Keine extra Spannungszuführung notwendig da Board über das I2C-Bus Kabel mit Strom verorgt wird
    Programmierbare Helligkeit
    Jedes einzelne Segment der 7-Segmentanzeige kann angesteuert werden
    4 Dezimalpunkte möglich
    Controller wird nicht belastet. Die Ziffern werden solange angezeigt, bis neue Ziffer gesendet wird. Keine Interrupts oder Bus-Belastung!
    Preisgünstig und schneller Aufbau in wenigen Minuten möglich
    4 verschiedene Slave Adressen per Jumper wählbar
    Kleines Lochraster Experimentierfeld für Erweiterungen Taster, I2C-Baustein (Funkuhr etc.) etc.
    Kompakt, Roboternetz-Standard-Format 100x78 (halbes Euroformat), Huckepack mit anderen Boards kombinierbar
    Wahlweise mit großen oder kleineren Segmenten bestückbar (Bausatz inkl. große)
    Platinen und Bausatzservice
    Deutsche Doku mit Programmbeispielen für RN-Control und RNBFRA-Board

The PCF8584 and the PCA9564 are bus controller devices performing the following functions:
- Receive data in a parallel format from a microcontroller/microprocessore, convert them to a serial format conforming
to the I2C protocol and send them to I2C devices located on the bus
- Receive serial data from the I2C-bus, convert them to a parallel format and send them to the microcontroller /
microprocessor connected to the controllers
http://www.nxp.com/documents/application_note/AN10148.pdf

The PCA9564 is an integrated circuit designed in CMOS technology that serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to communicate bi-directionally with the I2C-bus.
