• Supports low-voltage CardBus card detection and 16-bit PC Card power management
• Includes an internal low-dropout voltage regulator (LDO-VR) and clock run protocol

Controllers Applications

• Single-slot CardBus expansion in portable computing devices
• IEEE 1394 (FireWire) connectivity implementation
• PC Card and Smart Card interface solutions

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct package type and temperature range. Confirm that the component meets current RoHS compliance standards before procurement. Review the latest datasheet revisions for any updates to pin assignments or electrical characteristics.

Controllers Selection Notes

Select this controller for designs requiring a unified CardBus and FireWire solution in a single package. Ensure the host system supports the required PCI configuration space and provides adequate power delivery for the integrated LDO-VR. Verify compatibility with the target operating system's driver requirements for both CardBus and OHCI functions.

Controllers Part Context

This component belongs to the PCIxx12 family of multifunctional terminals from Texas Instruments. The family shares common architectural features but varies in supported interfaces and performance levels. The ZHK suffix typically denotes a specific package variant within this product line.

Controllers Replacement Considerations

Consult the PCIxx12 data manual for confirmed substitute part numbers within the same family. Verify functional equivalence regarding CardBus and OHCI specifications before substitution.
