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.
