PCI7610GHK

Controllers Overview

The PCI7610GHK is a Texas Instruments integrated single-socket UltraMedia PC Card controller featuring an IEEE 1394a-2000 OHCI link-layer controller and two-port PHY. It supports PC Card or CardBus with hot insertion/removal, compliant with PC Card Standard 8.0 and Intel Mobile Power Guidelines. The device includes a dedicated interface for Smart Card, SD/MMC, or Memory Stick sockets. It operates at a 33-MHz PCI clock rate with 1.8-V core logic and 3.3-V I/O cells. Data transfer rates on the 1394 bus reach up to 400 Mbits/s (S400), supporting burst transfers of 132 MBps. The package is a Microstar BGA with 209 pins.

Controllers Feature Summary

• Integrated dual-functionality combining a PC Card/Smart Card socket controller with a fully compliant IEEE 1394a-2000 OHCI host controller and PHY.
• Supports high-speed data throughput via PCI bus mastering and deep FIFOs, enabling sustained bursting and optimized latency tolerance.
• Includes advanced power management features compliant with ACPI and PCI Bus Power Management specifications, including low-power sleep modes.
• Provides flexible multifunction terminals for system integration, supporting serialized IRQs, ring indicators, and general-purpose inputs/outputs.

Controllers Applications

• High-performance laptop computers requiring simultaneous PC Card and FireWire connectivity
• Mobile workstations needing secure storage interfaces for Smart Cards or SD/MMC media
• Industrial control systems utilizing IEEE 1394 serial bus for peripheral communication

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct TI channels. Confirm RoHS compliance status and lead-free soldering suitability prior to assembly. Review the latest datasheet revisions for any parameter updates. Ensure design-in compatibility with existing motherboard BIOS and driver support structures. Validate pinout alignment with the specific Microstar BGA footprint requirements.

Controllers Selection Notes

Select this component for designs requiring a unified solution for legacy PC Card expansion and modern IEEE 1394 connectivity. Consider the 209-pin BGA package constraints during PCB layout planning. Evaluate thermal dissipation requirements given the CMOS process technology. Assess firmware loading capabilities via Function 3 for custom subsystem ID implementations. Compare against newer successors if new design recommendations are strictly required.

Controllers Part Context

This device belongs to Texas Instruments' UltraMedia series, bridging PC Card standards with IEEE 1394 technologies. It serves as a bridge between the PCI local bus and external serial bus networks. The part integrates multiple functions into a single chip, reducing board space compared to discrete solutions. It represents a specialized peripheral controller designed for mobile computing architectures from the mid-2000s era.

Controllers Replacement Considerations

Texas Instruments lists the PCI7421ZHK as the replacement for the PCI7610GHK. Verify register compatibility and pinout mapping before substitution. Review the target component's feature set to ensure all original functionalities are supported in the new design.
