GENERAL DESCRIPTION
The OZ6812 is an ACPI and PC98/99 logo certified, high
performance, 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
1998 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 development of many new
functions and applications.
The OZ6812 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. The device
also provides a power-down mode to allow host software to
reduce power consumption further by stopping internal
clock distribution as well as the PC Card socket clock. In
addition, an advanced CMOS process is utilized to
minimize system power consumption.
The OZ6812 single PCMCIA socket supports 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 1998 PC Card Standard CardBus specification. The
OZ6812 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 OZ6812 supports dynamic PC
Card hot insertion and removal, with auto configuration
capabilities.
The OZ6812 is fully compliant with the 33Mhz PCI Bus
specification, V2.2. It supports a master device with
internal CardBus direct data transfer. The OZ6812
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 (composed of 16 double words) permits the OZ6812
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.
