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
OZ6933
ACPI CardBus Controller
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.
The OZ6933 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 D3cold
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 OZ6933
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 OZ6933 dual PCMCIA socket supports two 3.3V/5V
8/16-bit PC Card R2 cards or 32-bit CardBus R3 cards. 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
OZ6933 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 OZ6933 supports dynamic PC
Card hot insertion and removal, with auto configuration
capabilities.
The OZ6933 is fully compliant with the 33Mhz PCI Bus
specification, v2.2. It supports a master device with intern-
al CardBus direct data transfer. The OZ6933 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
OZ6933 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 OZ6933 is a PCMCIA R2/CardBus controller, providing
the most advanced design flexibility for PC Cards that inter-
face with advanced notebook designs.
