Integrated PC Card

The Texas Instruments PCI4410A device is an integrated single-socket PC Card controller and IEEE 1394 Open HCI host controller. This high-performance integrated solution provides the latest in both PC Card and IEEE 1394 technology.
The PCI4410A device is a dual-function PCI device compliant with the PCI Local Bus Specification. Function 0 provides the independent PC Card socket controller compliant with the PC Card Standard. The PCI4410A device 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 buffered internally to allow hot insertion and removal without external buffering. The PCI4410A device is compatible with the Register of the Intel? 82365SL-DF and 82365SL ExCA controllers. The PCI4410A 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 PCI4410A device CAN be programmed to accept posted writes to improve bus utilization. Function 1 of the PCI4410A device is compatible with IEEE 1394a-2000 and the latest 1394 open host controller Interface (OHCI) specifications. The chip provides the IEEE 1394 link function and is compatible with data rates of 100, 200, and 400 Mbits/s. Deep FIFOs are provided to Buffer 1394 data and accommodate large host bus latencies. The PCI4410A device 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 PCI4410A device the best-in-class 1394 OHCI solution.
The PCI4410A device provides an internally buffered zoomed-video (ZV) path. This reduces the design effort of PC board manufacturers to add a ZV-compatible solution and ensures compliance with the CardBus loading specifications.
Various implementation-specific functions and general-purpose inputs and outputs are provided through eight multifunction terminals. These terminals present a system with options in PC PCI DMA, PCI LOCK and parallel interrupts, PC Card activity indicator LEDs and other platform-specific signals. ACPI-compliant general-purpose events CAN be programmed and controlled through the multifunction terminals, and an ACPI-compliant programming Interface is included for the general-purpose inputs and outputs.
The PCI4410A device 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. The PC Card (CardBus) Controller and IEEE 1394 Host Controller Device Class Specifications required for Microsoft OnNow? Power Management are supported. Furthermore, an advanced complementary metal-oxide semiconductor (CMOS) process achieves low system power consumption.
Unused PCI4410A device inputs must be pulled to a valid Logic level using a 43-k resistor.
