PCI7510PDV

Specialized Overview

The Texas Instruments PCI7510 is an integrated single-socket PC Card controller featuring an IEEE 1394 Open Host Controller Interface (OHCI) link-layer controller and a two-port PHY. It supports data transfer rates of 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s on the FireWire interface. The device operates with a 1.8-V core logic and 3.3-V I/O cells, utilizing an internal voltage regulator. It provides a dedicated Smart Card socket interface and supports both 16-bit PC Cards and CardBus cards at 5 V or 3.3 V. The controller functions as a four-function, 33-MHz PCI device compliant with PCI Local Bus Specification Revision 2.3.

Specialized Feature Summary

• Integrates a PC Card/Smart Card controller with a dual-port IEEE 1394a-2000 OHCI host controller and PHY
• Supports hot insertion and removal for PC Cards without external buffering
• Includes deep FIFOs and physical write posting to maximize data throughput and tolerate host latency
• Provides comprehensive power management features including D0-D3 states and automatic port power-down

Specialized Applications

• PC Card and CardBus expansion solutions for portable computers
• Integrated FireWire connectivity for digital cameras and storage devices
• Smart Card reader implementations in mobile platforms

Specialized Procurement Notes

Verify component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type and pinout compatibility with the target PCB layout. Ensure that the firmware loading mechanism via Function 3 is supported by the system driver architecture. Validate that the required 24.576-MHz crystal reference is included in the design.

Specialized Selection Notes

Select this component for designs requiring a unified solution for PC Card, Smart Card, and FireWire interfaces in a single socket. Ensure the system supports the necessary 1.8-V core voltage generation and 3.3-V I/O signaling. Verify that the application requires compliance with IEEE Std 1394a-2000 and PCI Local Bus Specification Revision 2.3. Consider the availability of the specific BGA package variant for the manufacturing process.

Specialized Part Context

The PCI7510 serves as a multifunction bridge between the PCI bus and peripheral interfaces, combining legacy PC Card support with modern high-speed serial bus capabilities. It replaces discrete controllers for PC Card sockets and FireWire PHYs, reducing board space and complexity. The device is designed for high-volume PC applications, offering register compatibility with Intel 82365SL-DF ExCA controllers.
