PCI7410PDV

Controllers Overview

The PCI7410PDV is a single-socket UltraMedia PC Card controller integrating an IEEE 1394a-2000 OHCI link-layer controller and two-port PHY. It supports PC Card Standard 8.0, Intel Mobile Power Guidelines, and PCI Bus Power Management Interface Specification 1.1. The device features a 33-MHz PCI bus interface compatible with 3.3-V and 5-V signaling environments. It provides two IEEE 1394a-2000 cable ports operating at 100M bits/s, 200M bits/s, and 400M bits/s. The package type is LQFP-208.

Controllers Feature Summary

• Integrates a dedicated interface for Secure Digital (SD)/MultiMediaCard (MMC) or Memory Stick sockets alongside the primary PC Card socket.
• Supports hot insertion and removal of cards without requiring external buffering due to internally buffered card signals.
• Includes deep FIFOs and physical write posting buffers to maximize data throughput and tolerate large host latency on both the PCI and CardBus buses.

Controllers Applications

• Bridging between the PCI bus and PC Cards in high-volume PC applications
• Systems requiring integrated IEEE 1394 connectivity via Open Host Controller Interface
• Devices utilizing SD/MMC or Memory Stick memory expansion

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific revision matches design requirements. Check for end-of-life status as indicated by Texas Instruments documentation. Ensure compliance with RoHS standards relevant to the manufacturing date. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Controllers Selection Notes

Select this component when a unified solution for PC Card, FireWire, and flash memory interfaces is required within a single socket. Consider the LQFP-208 package constraints during layout planning. Evaluate power management capabilities if battery-operated applications are targeted. Verify system clock requirements against the specified 24.576-MHz crystal reference.

Controllers Part Context

This device belongs to the Texas Instruments UltraMedia PC Card controller family. It serves as a bridge between the PCI local bus and various peripheral standards including PC Card, IEEE 1394, and memory card interfaces. The integration reduces board space and simplifies system architecture compared to discrete controller solutions.

Controllers Replacement Considerations

Texas Instruments indicates that the PCI7410GHK variant has been replaced by the PCI7421ZHK. Verify functional equivalence and pinout compatibility before substituting components in existing designs.
