Functions 0 and 1 provide the independent PC Card socket controllers compliant with the PC Card Standard (Release
8.1). The PCI6421 controller provides features that make it the best choice for bridging between the PCI bus and PC
Cards, and supports any combination of Smart Card, Flash Media, 16-bit, CardBus, and USB custom card interface
PC Cards in the two sockets, powered at 5 V or 3.3 V, as required.
All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI6421
controller is register compatible with the Intel 82365SL-DF ExCA controller. The PCI6421 internal data path logic
allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance. Independent
buffering and a pipeline architecture provide an unsurpassed performance level with sustained bursting. The
PCI6421 controller can be programmed to accept posted writes to improve bus utilization.
Function 3 of the PCI6421 controller is a PCI-based Flash Media controller that supports Memory Stick, Memory
Stick-Pro, SmartMedia, XD, SD, and MMC cards. This function controls communication with these Flash Media cards
through a passive PC Card adapter or through a dedicated Flash Media socket. In addition, this function includes DMA
capabilities for improved Flash Media performance.
Function 4 of the PCI6421 controller is a PCI-based SD host controller that supports MMC, SD, and SDIO cards. This
function controls communication with these Flash Media cards through a passive PC Card adapter or through a
dedicated Flash Media socket. In addition, this function is compliant with the SD Host Controller Standard
Specification and includes both DMA capabilities and support for SD suspend/resume.
1.1.3 PCI6611 Controller
The PCI6611 controller is a four-function PCI controller compliant with PCI Local Bus Specification, Revision 2.3.
Function 0 provides an independent PC Card socket controller compliant with the PC Card Standard (Release 8.1).
The PCI6611 controller provides features that make it the best choice for bridging between the PCI bus and PC Cards,
and supports Smart Card, Flash Media, 16-bit, CardBus or USB custom card interface PC Cards, powered at 5 V
or 3.3 V, as required.
All card signals are internally buffered to allow hot insertion and removal without external buffering. The PCI6611

Function 4 of the PCI6611 controller is a PCI-based SD host controller that supports MMC, SD, and SDIO cards. This
function controls communication with these Flash Media cards through a passive PC Card adapter or through a
dedicated Flash Media socket. In addition, this function is compliant with the SD Host Controller Standard
Specification and includes both DMA capabilities and support for SD suspend/resume.
Function 5 of the PCI6611 controller is a PCI-based Smart Card controller used for communication with Smart Cards
inserted in PC Card adapters. Utilizing Smart Card technology from Gemplus, this function provides compatibility with
many different types of Smart Cards.
1.1.4 PCI6411 Controller
The PCI6411 controller is a three-function PCI controller compliant with PCI Local Bus Specification, Revision 2.3.
Function 0 provides an independent PC Card socket controller compliant with the PC Card Standard (Release 8.1).
The PCI6411 controller provides features that make it the best choice for bridging between the PCI bus and PC Cards,
and supports Smart Card, Flash Media, 16-bit, CardBus or USB custom card interface PC Cards, powered at 5 V
or 3.3 V, as required.
