GENERAL DESCRIPTION
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
PCMCIA. The CardBus provides 32-bit interface with
multiplexed address and data lines. This will allow the
addition
of
high
performance
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
Management

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.
To enhance the performance between the PCI bus and any
CardBus card, two buffers (each composed of 16 double
words) are added on both sides going from PCI to CardBus
or the other way around. By implementing these buffers,
the OZ6833 will not refuse data from a target bus while
moving data and preventing deadlock situations.
In order to allow maximum flexibility for system designers,
the CINT# of the PC card 32-bit may be programmed to
steer to either INTA# or INTB# of the PCI bus. Further, the
interrupts may be programmed to route through the bridge
to either PCI INT lines or IRQ interrupts on the ISA bus.
