APPLICATION INFORMATION
overview
PC Cards were initially introduced as a means to add EEPROM (flash memory) to portable computers with
limited onboard memory. The idea of add-in cards quickly took hold; modems, wireless LANs, Global Positioning
Satellite System (GPS), multimedia, and hard-disk versions were soon available. As the number of PC Card
applications grew, the engineering community quickly recognized the need for a standard to ensure
compatibility across platforms. To this end, the PCMCIA (Personal Computer Memory Card International
Association), comprising members from leading computer, software, PC Card, and semiconductor
manufacturers, was established. One key goal was to realize the plug-and-play concept. Cards and hosts from
different vendors should be compatible or able to communicate with one another transparently.
PC Card power specification
System compatibility also means power compatibility. The most current set of specifications (PC Card Standard)
set forth by the PCMCIA committee states that power is to be transferred between the host and the card through
eight of the 68 terminals of the PC Card connector. This power interface consists of two VCC, two Vpp, and four
ground terminals. Multiple VCC and ground terminals minimize connector terminal and line resistance. The two
Vpp terminals were originally specified as separate signals, but are commonly tied together in the host to form
a single node to minimize voltage losses. Card primary power is supplied through the VCC terminals;
flash-memory programming and erase voltage is supplied through the Vpp terminals.
