PCI4451 General Description

The Texas Instruments PCI4451 is an integrated dual-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 PCI4451 is a three-function PCI device compliant with PCI Local Bus Specification 2.2. Functions 0 and 1 provide the independent PC Card socket controllers compliant with the 1997 PC Card Standard. The PCI4451 provides features that make it the best choice for bridging between the PCI bus and PC Cards, and supports any combination of 16-bit and CardBus PC Cards in the two sockets, 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 PCI4451 is register compatible with the Intel 82365SLDF ExCA controller. The PCI4451 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 PCI4451 can be programmed to accept posted writes to improve bus utilization.

Function 2 of the PCI4451 is compatible with IEEE 1394A 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 per second. Deep FIFOs are provided to buffer 1394 data and accommodate large host bus latencies. The PCI4451 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 PCI4451 an excellent 1394 open HCI solution.

The PCI4451 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 may be programmed and controlled through the multifunction terminals, and an ACPI-compliant programming interface is included for the general-purpose inputs and outputs.

The PCI4451 is compliant with PCI Bus Power Management Specification 1.1, and provides several low-power modes which 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.
