PCI7510GHK

Specialized Overview

The Texas Instruments PCI7510GHK is an obsolete single-socket PC Card controller featuring an IEEE 1394a-2000 OHCI two-port PHY/link-layer controller and a dedicated Smart Card interface. It operates as a four-function, 33-MHz PCI device compliant with the PCI Local Bus Specification Revision 2.3 and PC Card Standard 8.0. The integrated solution supports data transfers at 100M bits/s, 200M bits/s, and 400M bits/s between the PCI bus and the 1394 bus. It utilizes a 1.8-V core logic with 3.3-V I/O cells and includes an internal voltage regulator. The device supports PCI power management states D0 through D3 and provides deep FIFOs to tolerate large host latency.

Specialized Feature Summary

• Integrates a fully interoperable IEEE 1394a-2000 OHCI host controller with a two-port PHY supporting S100, S200, and S400 speeds.
• Provides a dedicated socket interface for Smart Cards alongside standard PC Card and CardBus support.
• Includes advanced power-down features and ACPI compliance to conserve energy in battery-powered applications.
• Supports serialized IRQs, hot insertion/removal, and physical write posting to maximize data throughput.

Specialized Applications

• High-volume PC applications requiring integrated FireWire connectivity
• Systems needing simultaneous PC Card and Smart Card expansion capabilities
• Battery-operated portable devices requiring low-power sleep modes

Specialized Procurement Notes

Verify component status before design implementation. This specific part number is classified as obsolete by the manufacturer. Production has been discontinued, meaning new manufacturing units are no longer available. Engineers must confirm availability through secondary market channels or consider alternative components for new designs to ensure long-term supply stability.

Specialized Selection Notes

Select this component only for maintenance of existing legacy systems where register compatibility with Intel 82365SL-DF is required. Evaluate the need for dual IEEE 1394 ports and Smart Card integration against modern alternatives. Ensure system design accommodates the 24.576-MHz crystal reference and 3.3-V/5-V PCI signaling environments specified in the datasheet.

Specialized Part Context

The PCI7510 series represents an integrated bridge solution combining PC Card, Smart Card, and FireWire technologies into a single package. It was designed to simplify motherboard layouts for laptops and desktops by consolidating multiple controller functions. The GHK suffix denotes the Microstar BGA package variant containing 209 pins.

Specialized Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Due to the obsolete status, engineers should evaluate newer multi-function controllers or separate discrete PHY and bridge solutions that meet current IEEE 1394 standards and PCI Express requirements.
