PCI4410AGHK

Controllers Overview

The PCI4410AGHK is a single-chip controller from Texas Instruments that integrates a CardBus bridge, a 16-bit PC Card controller, and an OHCI-compliant IEEE 1394 (FireWire) host controller. Designed for portable computing platforms, it provides comprehensive connectivity solutions by supporting both legacy PC Card standards and high-speed serial data transfer protocols. The device manages power sequencing, interrupt routing, and distributed DMA operations to ensure efficient system resource allocation. It operates within standard industrial temperature ranges and utilizes a MicroStar BGA package for compact board integration.

Controllers Feature Summary

• Integrates a fully compliant CardBus bridge alongside a dedicated 16-bit PC Card controller on a single die.
• Includes an Open Host Controller Interface (OHCI) compliant IEEE 1394a PHY and link layer for FireWire connectivity.
• Supports Distributed DMA (DDMA) architecture to optimize bus bandwidth utilization for PC Card-16 applications.
• Features integrated pullup resistors and programmable interrupt subsystems for simplified interface design.

Controllers Applications

• Portable computer expansion slots requiring simultaneous CardBus and legacy PC Card support
• Industrial control systems utilizing IEEE 1394 high-speed data acquisition
• Embedded networking hardware with integrated peripheral management capabilities

Controllers Procurement Notes

Verify the specific suffix 'GHK' corresponds to the required MicroStar BGA package variant during sourcing. Confirm that the component meets the necessary RoHS compliance standards for your target market. Ensure that the ordering documentation explicitly references the TI datasheet SCPS059 to validate technical specifications against current manufacturing revisions.

Controllers Selection Notes

Select this component when a design requires a unified solution for managing multiple legacy and high-speed peripheral interfaces without consuming excessive board space. It is suitable for architectures needing robust power management features and direct access to IEEE 1394 networks. Evaluate the thermal requirements of the BGA package relative to the host system's cooling capabilities before finalizing the bill of materials.
