The Texas Instruments PCI7410 device is an integrated single-socket UltraMedia™ PC Card controller with an

IEEE 1394 open host controller link-layer controller (LLC) and two-port 1394 PHY. The PCI7410 controller also

includes a dedicated interface that can be used as a Secure Digital (SD)/MultiMediaCard (MMC), or Memory

Stick socket. This high performance integrated solution provides the latest in PC Card, IEEE 1394, and

UltraMedia™ technology.

The PCI7410 CardBus controller is a four-function, 33-MHz PCI device compliant with the PCI Local Bus

Specification. Function 0 provides a PC Card socket controller compliant with the latest PC Card Standards.

Function 1 provides a dedicated socket for either SD/MMC or Memory Stick. Function 2 of the PCI7410

controller is an integrated IEEE 1394 OHCI host controller and two-port PHY. Function 3 is the interface to load

the PCI7410 program RAM with firmware. The PCI7410 controller provides features that make it the best choice

for bridging between the PCI bus and PC Cards, and supports any combination of 16-bit and CardBus cards

powered at 5 V or 3.3 V as required.

There is no PCMCIA card and socket service software changes required to move systems from the existing

CardBus socket controller to the PCI7410 controller. The PCI7410 controller is register compatible with the Intel

82365SL–DF ExCA controller and implements the host interface defined in the PC Card Standard. The PCI7410

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 the pipeline architecture provide an unsurpassed

performance level with sustained bursting. The PCI7410 controller can be programmed to accept posted writes

to improve bus utilization. All card signals are internally buffered to allow hot insertion and removal without

external buffering.

Function 1 of the PCI7410 controller provides a dedicated interface for either a Secure Digital (and MMC) or

Memory Stick socket. Secure Digital cards are based upon the MultiMediaCard (MMC). SD is essentially a

superset of MMC. The additional security features of the SD cards also allow their use in more-secure

applications or in devices where content protection is essential. Memory Stick cards are about the size of a stick

of gum and are 2,8 mm thick. Developed by Sony, there are two types of Memory Stick cards, the standard

Memory Stick and MagicGate Memory Stick. MagicGate technology provides security to Memory Stick cards so

that they can be used to store and protect copyrighted data.

Function 2 of the PCI7410 controller is an integrated 1394a-2000 OHCI PHY/link-layer controller (LLC) that is

fully compliant with the PCI Local Bus Specification, the PCI Bus Power Management Interface Specification,

IEEE Std 1394-1995, IEEE Std 1394a-2000, and the 1394 Open Host Controller Interface Specification. It is

capable of transferring data between the 33-MHz PCI bus and the 1394 bus at 100M bits/s, 200M bits/s, and

400M bits/s. The PCI7410 controller provides two 1394 ports that have separate cable bias (TPBIAS). The

PCI7410 controller also supports the IEEE Std 1394a-2000 power-down features for battery-operated

applications and arbitration enhancements.

As required by the 1394 Open Host Controller Interface Specification (OHCI) and IEEE Std 1394a-2000, internal

control registers are memory-mapped and non-prefetchable. The PCI configuration header is accessed through

configuration cycles specified by PCI, and it provides plug-and-play (PnP) compatibility. Furthermore, the

PCI7410 controller is compliant with the PCI Bus Power Management Interface Specification as specified by the

PC 2001 Design Guide requirements. The PCI7410 controller supports the D0, D1, D2, and D3 power states.

Function 3 of the PCI7410 controller is the interface to load the PCI7410 program RAM with firmware. This

function provides an I/O window that a software driver uses to load the PCI7410 firmware into the internal RAM.
