CardBus Protocol

  Bus Doctor CardBus protocol analyzer bus pod  

CardBus is based upon the same physical specifications as PCMCIA and uses the same connectors. It's different from other PC cards in that CardBus has a 32-bit multiplexed address/data path, which operates at PCI local-bus speeds of up to 33 MHz, producing a peak bandwidth of 132MB/sec. CardBus accomplishes this by adopting the synchronous burst-transfer orientation of PCI, as well as a bus protocol, which is essentially identical to that of PCI.

Besides supporting a PCI-like data rate, CardBus devices are capable of acting as system-bus masters; that is, they can assume control of the system bus (or busses) to effect data transfers.
