Function 5 of the PCI7621 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.
1.1.2 PCI7421 Controller
The PCI7421 controller is a five-function PCI controller 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
8.1). The PCI7421 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 PCI7421
controller is register compatible with the Intel 82365SL-DF ExCA controller. The PCI7421 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
PCI7421 controller can be programmed to accept posted writes to improve bus utilization.
Function 2 of the PCI7421 controller is compatible with IEEE Std 1394a-2000 and the latest 1394 Open Host
Controller Interface Specification. The chip provides the IEEE1394 link and 2-port PHY function and is compatible
with data rates of 100, 200, and 400 Mbits per second. Deep FIFOs are provided to buffer 1394 data and
accommodate large host bus latencies. The PCI7421 provides physical write posting and a highly tuned physical data
path for SBP-2 performance.
Function 3 of the PCI7421 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 PCI7421 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 PCI7611 Controller
