The PCI4410 is a dual-function PCI device compliant with PCI Local Bus Specification 2.2. Function 0
provides the independent PC Card socket controller compliant with the 1997 PC Card Standard. The
PCI4410 provides features that make it the best choice for bridging between the PCI bus and PC Cards, and
supports either 16-bit or CardBus PC Cards in the socket, powered at 5 V or 3.3 V, as required.
All card signals are internally buffered to allow hot insertion and removal without external buffering. The
PCI4410 is register compatible with the Intel
TM
82365SLF and 82365SL ExCA controllers. The PCI4410
internal data path logic allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for
maximum performance. Independent buffering and a pipeline architecture provide an unsurpassed
performance level with sustained bursting. The PCI4410 can be programmed to accept posted writes to
improve bus utilization.
Function 1 of the PCI4410 is compatible with IEEE1394A and the latest 1394 open host controller interface
(OHCI) specifications. The chip provides the IEEE1394 link function and is compatible with data rates of 100,
200, and 400Mbits per second. Deep FIFOs are provided to buffer 1394 data and accommodate large host bus
latencies. The PCI4410 provides physical write posting and a highly tuned physical data path for SBP-2
performance. Multiple cache line burst transfers, advanced internal arbitration, and bus holding buffers on the
PHY/Link interface are other features that make the PCI4410 the best-in-class 1394 Open HCI solution.
