Texas Instruments PCI7611 4 PCI7411 Controller, Multifunctional Terminals, Power Switch Interface

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 PCI7611 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 PCI7611 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.

1.1.4PCI7411 Controller

The PCI7411 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 PCI7411 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 PCI7411 controller is register compatible with the Intel 82365SL-DF ExCA controller. The PCI7411 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 PCI7411 controller can be programmed to accept posted writes to improve bus utilization.

Function 2 of the PCI7411 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 PCI7411 controller provides physical write posting and a highly tuned physical data path for SBP-2 performance.

Function 3 of the PCI7411 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 PCI7411 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.

1.1.5Multifunctional Terminals

Various implementation-specific functions and general-purpose inputs and outputs are provided through eight multifunction terminals. These terminals present a system with options in PC/PCI DMA, serial and parallel interrupts, PC Card activity indicator LEDs, flash media LEDs, and other platform-specific signals. PCI complaint 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.

1.1.6PCI Bus Power Management

The PCI7x21/PCI7x11 controller 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.

1.1.7Power Switch Interface

The PCI7x21/PCI7x11 controller also has a three-pin serial interface compatible with the Texas Instruments TPS2228 (default), TPS2226, TPS2224, and TPS2223A power switches. All four power switches provide power to the CardBus socket(s) on the PCI7x21/PCI7x11 controller. The power to each dedicated socket is controlled through separate power control pins. Each of these power control pins can be connected to an external 3.3-V power switch.
