The PC Card Standard provides physical specifications for three types of PC Cards, with additional provisions for extended cards. All three card types measure the same length and width and use the same 68-pin connector. Because they differ only in thickness and not electrical/software interface, a thinner card can be used in a thicker slot, but a thicker card can not be used in a thinner slot. Only the mechanical size of the larger card prevents it from fitting into the smaller slot. +==========+=========+=========+====================================+ | | Length | Width | Thickness | Typical Usage* +==========+=========+=========+===========+========================+ | Type I | 85.6 mm | 54.0 mm | 3.3 mm | Memory (SRAM,Flash,etc) +———-+———+———+———–+————————+ | Type II | ” | ” | 5.0 mm | I/O (Modem,LAN,etc) +———-+———+———+———–+————————+ | Type III | ” | ” | 10.5 mm | Rotating Mass Storage +———-+—–
