Features :

The R5C551 is the single chip solution offering single PCI bus-PC Card Bridge. The R5C551 is compliant with the

latest specification in both PC card and IEEE 1394. The R5C551 has two PCI functions compliant, the PC Card

interface and the IEEE 1394 interface. The PC Card controller of the R5C551 is compliant with PC Card Standard

Release 7.0. The R5C551 provides features that make it the best choice for bridging between the PCI bus and PC

Cards, and supports any combination of 16-bit (Card-16), and CardBus (Card-32) PC Cards in one socket, powered at

5V or 3.3V, as required. The R5C551 provides the IEEE1394 OHCI-Link and two ports the IEEE1394 PHY that are

compliant with the IEEE1394-1995, IEEE1394a-2000 and the latest 1394 OHCI specifications. The R5C551 data rate

is capable of 100, 200, and 400Mbits per second.The R5C551 is compliant with the latest PCI Bus Power

Management Specification, and provides several low-power modes that enable the host power system to further

reduce power consumption.
