ExpressCard™ host connectors, systems, module components and kits from FCI support host systems and module manufacturers’ implementation of ExpressCard technology. The Personal Computer Memory Card International Association (PCMCIA) has developed the ExpressCard Standard as replacement for the PC Card Standard, which defines the popular CardBus and PC Card add-in cards. The new standard will carry forward the benefits of removable communication, storage, I/O, multimedia, security and adapter cards to new generations of mobile and desktop personal computers. The ExpressCard standard supports both USB 2.0 and PCI Express™ high-speed serial interfaces. Mobile and desktop host systems can choose to incorporate universal slots, which can accommodate either ExpressCard/34 or ExpressCard/54 module sizes, or ExpressCard/34 slots when space is at a premium. Both are smaller than today’s CardBus slot implementations.
