The PCMCIA I/O interface, developed more than 10 years
ago and initially used for memory cards, defines a standard
68-pin connector and comes in a Type 1, 2, and 3 format
(varying thicknesses), though Type 2 is the most prevalent.
Since then, the PCMCIA 16-bit interface has been improved
with a 32-bit CardBus interface designed to meet the demands
of multimedia and other high-bandwidth applications. The
latest development is the ExpressCard (www.expresscard.org)
interface, which increases the I/O performance by supporting
both the PCI Express and USB 2.0 standard. |
