Acpi Cardbus Controller

The OZ6833 ACPI CardBus controller provides a high performance, synchronous, 32-bit, bus master/target Interface between computers and plug in PC Cards. CardBus is the new 32-bit Interface standard of Personal Computer Memory Card International Association, PCMCIA. The CardBus provides 32-bit Interface with multiplexed address and data lines. This will allow the addition of high performance computer system enhancements and new functions in a user-friendly way. Further, the expansion capability of the CardBus will provide benefits to the end user. CardBus is intended to support temporal add-in functions on PC Cards, such as Memory cards, Network Interfaces FAX/Modems and other Wireless Communication cards, etc. The high performance and capability of the CardBus Interface will enable further development of many new functions and applications. The OZ6833 CardBus controller is a 33MHz PCI compliant master/target device that attaches to the PCI bus and manages two PC Card sockets. The PC Card sockets support both 3.3V / 5V versions of 8/16-bit PCMCIA R2 card or 32-bit CardBus card. R2 card support is compatible with the Intel 82365SL PCIC controller. CardBus card support is fully compatible with the 1998 PC Card Standard V7.0. The OZ6833 is a stand alone device. It does not require an additional Buffer chip for the two PC Card socket Interface The OZ6833 is implemented with a complex multiple FIFO data Buffer for the PCI and CardBus Interface to provide better PCI CardBus access. The FIFO Buffers allow the bridge to accept data from a target bus while moving data to it, facilitating deadlock prevention. In addition, the OZ6833 is designed with dynamic PC Card hot insertion and removal and auto configuration capabilities. The OZ6833 ACPI CardBus Controller provides the power saving mixed 5V / 3.3V capability. An advance CMOS process minimizes system power consumption. The device also provides a power-down mode, allowing host software to reduce power consumption further while stopping internal Clock Distribution and the Clocks on PC Card sockets. The OZ6833 is not only a CardBus bridge, but also a socket controller. The OZ6833 supports two master devices and arbitrates the priority of each. Further, it supports inter CardBus direct data transfer. The Register set in the OZ6833 is the superset of the OZ67xx Register set, assuring full compatibility with existing socket/card-services software and PC-card applications. The OZ6833 provides the most advanced design flexibility for the PC Card Interface in notebook computer design. By Unkown
