controller.

This

high-performance integrated solution provides the latest in PC Card, Smart Card, SD, MMC, and Memory Stick

technology.

The Texas Instruments PCI6420 device is an integrated dual-socket PC Card controller and SD/MMC

MS/MS-Pro controller. This high-performance integrated solution provides the latest in PC Card, SD, MMC, and

Memory Stick technology.

For the remainder of this document, PCI6x20 refers to both devices: PCI6620 and PCI6420.

The PCI6620 and PCI6420 are three-function PCI devices compliant with PCI Local Bus Specification, Revision

2.3.

Functions 0 and 1 provide the independent PC Card socket controllers compliant with the PC Card Standard

(Release 8.0). The PCI6x20 device provides features that make it the best choice for bridging between the PCI

bus, PC Cards, and Smart Cards and supports any combination of 16-bit, CardBus PC Cards, or Smart Card

adapter in the socket powered at 5 V or 3.3 V, as required.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
