●The Texas Instruments PCI1620 is an integrated dual-socket PC Card controller, FlashMedia controller (SmartMedia Card, MultiMediaCard, SD Card, Memory Stick card) and Smart Card controller.
●The PCI1620 UltraMedia controller is a three-function PCI device compliant with _PCI Local Bus Specification_ 2.2. Functions 0 and 1 provide two independent PC Card socket controllers compliant with _PC Card Standard_ 8.0. Function 2 is the interface to load the PCI1620 program RAM with firmware. The PCI1620 provides features that make it ideal for bridging between the PCI bus and PC Cards, and supports any combination of 16-bit, CardBus, and UltraMedia PC Cards in the two sockets, powered at 5 V, 3.3 V, or 1.8 V as required.
●UltraMedia cards that comply with the latest PCMCIA standard provide for very low-cost flash media and Smart Card adapters, because the control logic is integrated into the PCI1620. The PCI1620 supports a passive 4-in-1 adapter, as well as active PC Card-style Flash media and Smart Card adapters.
●No PCMCIA card or socket service software changes are required to move systems from an existing CardBus socket controller to the PCI1620. The FlashMedia UltraMedia applications use existing host ATA drivers, and Texas Instruments provides a qualified Smart Card driver for UltraMedia-based Smart Card adapters. The PCI1620 is register compatible with the Intel 82365SLDF ExCA controller and implements the host interface defined in the _PC Card Standard_. The PCI1620 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 a high performance level with sustained bursting. The PCI1620 can be programmed to accept posted writes to improve bus utilization.
●Various implementation-specific functions and general-purpose inputs and outputs are provided through seven multifunction terminals. These terminals present a system with options for PCI LOCK, serial and parallel interrupts, PC Card activity indicator LEDs, and other platform-specific signals. ACPI-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 PCI1620 is compliant with _PCI Bus Power Management Interface Specification_ 1.1, and provides several low-power modes, which enable the host power system to further reduce power consumption. The PCI1620 also has a three-terminal serial interface compatible with both the TI TPS2226 and TPS2228 power switches.
