The Texas Instruments PCI7621 controller is an integrated dual-socket UltraMedia PC Card controller, Smart

Card controller, IEEE 1394 open HCI host controller and PHY, and flash media controller. This high-performance

integrated solution provides the latest in PC Card, Smart Card, IEEE 1394, Secure Digital (SD), MultiMediaCard

(MMC), Memory Stick/PRO, SmartMedia, and XD technology.

The Texas Instruments PCI7421 controller is an integrated dual-socket UltraMedia PC Card controller, IEEE

1394 Open HCI host controller and PHY, and flash media controller. This high-performance integrated solution

provides the latest in PC Card, IEEE 1394, SD, MMC, Memory Stick/PRO, SmartMedia, and XD technology.

The Texas Instruments PCI7611 controller is an integrated single-socket UltraMedia PC Card controller, Smart

Card controller, IEEE 1394 open HCI host controller and PHY, and flash media controller. This high-performance

integrated solution provides the latest in PC Card, Smart Card, IEEE 1394, SD, MMC, Memory Stick/PRO,

SmartMedia, and XD technology.

For the remainder of this document, the PCI7x21 controller refers to the PCI7621 and PCI7421 controllers, and

the PCI7x11 controller refers to the PCI7611 and PCI7411 controllers.

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.

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.

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.
