Description

The OZ6912 is an ACPI and PC98/99 Logo Certified, highperformance, single slot PC Card controller with a synchronous 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 of OZ6912 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 P 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.
 
The OZ6912 CardBus controller is compliant with the latest ACPI-PCI Bus Power Management Interface Specification. 

It supports all four power states and the PME# function for maximum power savings and ACPI compliance. Additional   compliance to OnNow Power Management includes D3 cold state support, paving the way for low sleep state power  consumption and minimized resume times. To allow host  software to reduce power consumption further, the OZ6912 provides a power-down mode in which internal clock  distribution and the PC Card socket clocks are stopped. An advanced CMOS process is also used to minimize system power consumption.
 
The OZ6912 single PCMCIA socket supports a mix and  match 3.3V/5V 8/16-bit PC Card R2 card or 32-bit CardBus R3 card. The R2 card support is compatible with the Intel  82365SL PCIC controller, and the R3 card support is fully compliant with the 2000 PC Card Standard CardBus  specification. The OZ6912 is a stand alone device, which  means that it does not require an additional buffer chip for the PC Card socket interface.  In addition, the OZ6912  supports dynamic PC Card hot insertion and removal, with auto configuration capabilities.
 
The OZ6912 is fully compliant with the 33Mhz PCI Bus  specification, v2.2.  It supports a master device with internal CardBus direct data transfer.  The OZ6912 implements a FIFO data buffer architecture between the PCI bus and  CardBus socket interface to enhance data transfers to  CardBus devices. The bi-directional FIFO buffer permits the OZ6912 to accept data from a target bus (PCI or CardBus interface) while simultaneously transferring data.  This  architecture not only speeds up data transfers but also  prevents system deadlocks. 

  The OZ6912 is a PCMCIA R2/CardBus controller, providing the most advanced design flexibility for PC Cards that  interface with advanced notebook designs.
