Hardware Functional Overview
and the R3 card support is fully compliant with the 2000 PC Card Standard CardBus
specification. The OZ6933 is 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 complains with the 33Mhz PCI Bus specification, v2.2. It supports a
master device with internal CardBus direct data transfer. The OZ6933 implements 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 interface with advanced notebook designs.
