24 PCI CardBus Controllers<br />
➔<br />
Design Considerations<br />
PCI CardBus is a PCMCIA-standardcompliant,<br />
32-bit, high-performance<br />
bus-mastering architecture for PC cards.<br />
TI’s CardBus controllers are especially<br />
suited for mobile systems because a<br />
compact card can be inserted completely<br />
within the host device, eliminating the<br />
need for external cabling.<br />
Key Features<br />
• Standard, broadly supported PC<br />
card form factor and connector<br />
• PCI performance level and busmaster<br />
capability<br />
• Low-voltage (3.3-V) operation with<br />
standardized power management<br />
• Ease of use through plug-and-play<br />
and hot-plug capabilities<br />
• CardBus slots offer full backward<br />
compatibility for PC Card-16 cards<br />

TI Integrated CardBus/Flash Media/<br />
1394/Smart Card Advantages<br />
• TI offers the fastest Flash media<br />
controllers available in the market with<br />
the PCI7621 device family via the use<br />
of a high-speed DMA interface<br />
• TI offers patent pending SD switching<br />
technology that allows the use of<br />
MMC and SD/SDIO cards on a single<br />
notebook platform<br />
• TI controllers support the latest Flash<br />
media interfaces including SD/SDIO,<br />
xD, MMC, SM, Memory Stick,<br />
Memory Stick PRO and SmartMedia<br />
• TI controllers support a dedicated<br />
EMV-compliant and B1-certified<br />
SmartCard interface<br />
• TI offers Linux driver support for flash<br />
media types including SD/MMC,<br />
MS/MS Pro, Smartmedia, and xD<br />

Patent pending dual host implementation in the<br />
PCI7621 and PCI7612 device families permits<br />
the use of both MMC and SD memory cards in<br />
the same Flash media slot. Without this implementation,<br />
the media slot will either support<br />
only SD cards or only MMC cards, which could<br />
frustrate the end users, as both cards are the<br />
identical form factor.<br />
