PCI1620GHK

Controllers Overview

The PCI1620GHK is an integrated dual-socket PC Card controller, FlashMedia controller, and Smart Card controller manufactured by Texas Instruments. It functions as a three-function PCI device compliant with PCI Local Bus Specification 2.2. The device supports serialized IRQ with PCI interrupts and adheres to PC Card Standard 8.0. It features a 32-bit external data bus width and supports host data transfer rates up to 132 MBps. The component utilizes a BGA package with 209 pins.

Controllers Feature Summary

• Dual independent PC Card socket controllers supporting 16-bit, CardBus, and UltraMedia cards
• Integrated voltage regulator for 1.8-V core logic with 3.3-V I/O cells
• Advanced filtering on card detect lines providing noise immunity
• Supports hot insertion and removal of PC Cards

Controllers Applications

• Bridging between the PCI bus and PC Cards in high-volume PC applications
• UltraMedia flash media and Smart Card adapter implementations
• Systems requiring mix-and-match 5-V/3.3-V 16-bit PC Cards and 3.3-V CardBus cards

Controllers Procurement Notes

Verify the current production status of the PCI1620GHK before design implementation. Official documentation indicates this specific part number is classified as obsolete. Confirm availability through authorized distributors or check for replacement components recommended by Texas Instruments for new designs.

Controllers Selection Notes

Select this component only if legacy support for the obsolete PCI1620 family is required. Ensure the system design accommodates the 209-pin BGA package constraints. Verify that the host platform supports the specified PCI interfaces and power requirements for 1.8-V core and 3.3-V I/O operation.

Controllers Part Context

The PCI1620 series serves as a multifunction PCI device designed for PC Card and UltraMedia control. The GHK suffix denotes the specific BGA Microstar package variant containing 209 pins. This component integrates control logic for PC Cards, FlashMedia, and Smart Cards into a single chip, reducing board space compared to discrete solutions.

Controllers Replacement Considerations

Texas Instruments lists the PCI1620GHK as obsolete. No direct public substitute part numbers are documented in the provided datasheet. Designers should consult Texas Instruments support for current recommendations or alternative devices suitable for new designs.
