GENERAL DESCRIPTION

The OZ6933 is an ACPI and PC98/99 logo certified, high performance, dual slot PC Card controller with a synchron ous 32-bit bus master/target PCI interface. This PC Card to PCI bridge host controller is compliant with the 2000 PC Card Standard. This standard incorporates the new 32-bit CardBus while retaining the 16-bit PC Card specification as defined by PCMCIA release 2.1. 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 the new development of many new functions and applications.
