PCMCIA INTERFACES
The PC/104-PCMCIA-1 comes with one dual-slot PCMCIA socket and can support PCMCIA
cards of Type I to III (2x Type I/II or 1x Type III). PCMCIA cards of Type I to III all have the
same planar or outline dimensions (54.00mm x 85.60mm). Card thickness also is the same
within the interconnect area of each card. Only the substrate area of the cards is different
and distinguishes the card types:
Type
Thickness
Type I cards
3.3 mm
Type II cards
5.0 mm
Type III cards
10.5 mm
PCMCIA cards and sockets are keyed to prevent cards from being inserted upside down.
Keying is accomplished at the edges of the PCMCIA card and the socket connector. The
keying also is different for standard cards (5V) and low-voltage cards (3.3V only). The
PC/104-PCMCIA-1 is designed for standard cards.
