DESCRIPTION
The Texas Instruments PCI7620 device is an integrated dual-socket PC Card controller, Smart Card controller,
IEEE 1394 open HCI host controller, and PHY, Secure Digital (SD)/MultiMediaCard (MMC), Memory Stick
(MS)/MS-Pro controller. This high-performance integrated solution provides the latest in PC Card, Smart Card,
IEEE 1394, SD, MMC, and Memory Stick technology.
The Texas Instruments PCI7420 device is an integrated dual-socket PC Card controller, IEEE 1394 Open HCI
host controller, and PHY, SD/MMC MS/MS-Pro controller. This high-performance integrated solution provides
the latest in PC Card, IEEE 1394, SD, MMC, and Memory Stick technology.
For the remainder of this document, the PCI7x20 device refers to both devices: PCI7620 and PCI7420.
The PCI7620 and PCI7420 are four-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 PCI7x20 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.
There are no PCMCIA card and socket service software changes required to move systems from the existing
CardBus socket controller to the PCI7x20 device. The PCI7x20 device is register compatible with the Intel
82365SL–DF ExCA controller and implements the host interface defined in the PC Card Standard. The PCI7x20
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 provides an unsurpassed
performance level with sustained bursting. The PCI7x20 device 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 2 of the PCI7x20 device is an integrated IEEE 1394a–2000 open host controller interface (OHCI)
PHY/link-layer controller (LLC) device 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 PCI7x20 device provides two 1394 ports that have
separate cable bias (TPBIAS). The PCI7x20 device 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 and IEEE Std 1394a–2000, internal control
registers are memory-mapped and nonprefetchable. The PCI configuration header is accessed through
configuration cycles specified by PCI, and it provides plug-and-play (PnP) compatibility. Furthermore, the
PCI7x20 device is compliant with the PCI Bus Power Management Interface Specification. The PCI7x20 device
supports the D0, D1, D2, and D3 power states.
The PCI7x20 design provides PCI bus master bursting, and is capable of transferring a cacheline of data at
132M bytes/s after connection to the memory controller. Because PCI latency can be large, deep FIFOs are
provided to buffer the IEEE 1394 data.
The PCI7x20 device provides physical write posting buffers and a highly-tuned physical data path for SBP-2
performance. The PCI7x20 device also provides multiple isochronous contexts, multiple cacheline burst
transfers, advanced internal arbitration, and bus-holding buffers.
The PCI7x20 PHY-layer provides the digital and analog transceiver functions needed to implement a two-port
node in a cable-based 1394 network. Each cable port incorporates two differential line transceivers. The
transceivers include circuitry to monitor the line conditions as needed for determining connection status, for
initialization and arbitration, and for packet reception and transmission.

SLLA252 – JULY 2006
The PCI7x20 PHY-layer requires only an external 24.576-MHz crystal as a reference for the cable ports. An
external clock may be provided instead of a crystal. An internal oscillator drives an internal phase-locked loop
(PLL), which generates the required 393.216-MHz reference signal. This reference signal is internally divided to
provide the clock signals that control transmission of the outbound encoded strobe and data information. A
49.152-MHz clock signal is supplied to the integrated LLC for synchronization and is used for resynchronization
of the received data. Data bits to be transmitted through the cable ports are received from the integrated LLC
and are latched internally in synchronization with the 49.152-MHz system clock. These bits are combined
serially, encoded, and transmitted at 98.304M, 196.608M, or 393.216M bits/s (referred to as S100, S200, or
S400 speeds, respectively) as the outbound data-strobe information stream. During transmission, the encoded
data information is transmitted differentially on the twisted-pair B (TPB) cable pair(s), and the encoded strobe
information is transmitted differentially on the twisted-pair A (TPA) cable pair(s).
Function 3 of the PCI7620 and PCI7420 devices is a dedicated socket that supports SD, MMC, Memory Stick,
and Memory Stick-Pro cards. The Flash Media dedicated socket provides separate terminals for SD/MMC and
Memory Stick signals so that both an SD/MMC card and a Memory Stick/Memory Stick-Pro card can be used
concurrently.
Various implementation specific functions and general-purpose inputs and outputs are provided through eight
multifunction terminals. These terminals present a system with options in PCI LOCK, serial and parallel
interrupts, PC Card activity indicator LEDs, and other platform specific signals. PCI-compliant general-purpose
events may be programmed and controlled through the multifunction terminals, and an ACPI-compliant
programming interface is included for the general-purpose inputs and outputs.
The PCI7x20 device is compliant with the latest PCI Bus Power Management Specification, and provides
several low-power modes, which enable the host power system to further reduce power consumption.
The PCI7x20 device also has a three-pin serial interface compatible with both the Texas Instruments TPS2226
and TPS2228 power switches. The TPS2226 or TPS2228 power switch provides power to the two CardBus
sockets on the PCI7x20 device. The power to each dedicated socket is controlled through separate power
control terminals. Each of these power control pins can be connected to an external 3.3-V power switch.
