PCI7412ZHK

Controllers Overview

The PCI7412ZHK is a single-socket CardBus controller with an integrated OHCI-compliant IEEE 1394a-2000 two-port PHY and link-layer controller. It supports PC Card, Flash Media, Smart Card, and SD Host interfaces within a multifunctional terminal architecture. The device operates as a PCI bus master and includes power management capabilities compliant with ACPI standards.

Controllers Feature Summary

• Integrates a single CardBus socket with an OHCI-compliant IEEE 1394a-2000 two-port PHY
• Supports multiple interface types including PC Card, Flash Media, Smart Card, and SD Host
• Includes an internal low-dropout voltage regulator (LDO-VR) for power supply sequencing

Controllers Applications

• Single-slot expansion cards requiring simultaneous CardBus and FireWire connectivity
• Multifunctional terminals integrating PC Card, flash media, and smart card readers
• Portable computing systems requiring integrated IEEE 1394 host controller functionality

Controllers Procurement Notes

Verify the specific suffix ZHK against the manufacturer's current documentation to confirm package type and temperature range specifications. Ensure compatibility with the target system's PCI configuration space requirements before procurement.

Controllers Selection Notes

Select this component when a design requires a unified solution for CardBus expansion and IEEE 1394 connectivity in a single slot. Evaluate the need for integrated LDO regulation versus external power management solutions based on board layout constraints.

Controllers Part Context

This part belongs to the PCIxx12 family of single-socket CardBus controllers from Texas Instruments. The family shares a common architecture but varies by integrated features such as the number of ports or supported interface types.

Controllers Replacement Considerations

Consult the official PCIxx12 data manual for confirmed substitute part numbers within the same family that offer equivalent or enhanced feature sets.
