Technology Standard
   Technology Standard:       
   Your choices are...         
   PC Card Standard 95       PC Card Standard 95 is the original PCMCIA device standard. It has a 68-pin interface with 16 bits of address and data. 
   CardBus Technology       CardBus technology runs at 33 MHz and is for cards with 32 bits of address and data. 
   Miniature Card Technology       Miniature card technology products are about one-fourth the size of PC Card Standard 95. These PCMCIA cards use StrataFlash® (Numonyx B.V.) technology, a multilevel cellular architecture; and µBGA, a type of ball grid array. Together, these two technologies provide a high-capacity flash card. Miniature cards have 60-pin connectors, and dimensions of 38 mm x 33 mm x 3.5 mm. They are 73% smaller than a full PC Card. 
   CompactFlash® and CF+® Standard       CompactFlash® is a very small, removable, mass storage PCMCIA device. CF® cards weigh a half-ounce. They are the size of a matchbook, with a thickness that is less than one-half of a current PCMCIA Type II card. CF cards are also one-fourth the volume of a PCMCIA card. Instead of using the 68 pins in PC Card Standard 95, a CF card has 50 pins but still conforms to PCMCIA ATA specs. CF cads can be easily slipped into a passive 68-pin Type II adapter card that fully meets PCMCIA electrical and mechanical interface specifications. The CF+® specification adds additional card functionality over the original CompactFlash card, including magnetic disk drive data storage and I/O cards such as Ethernet, serial, fax/modem, digital phone, universal serial bus (USB), barcode scanner, etc. CF+ cards use flash technology, which is a non-volatile storage solution that does not require a battery to retain data indefinitely. CompactFlash, CF, and CF+ are registered trademarks of the CompactFlash Association.  
   Other       Other unlisted technologies such as SmartMedia and CardBay. SmartMedia is about one-third the area of a conventional PC card with dimensions measuring 45.0 mm x 37.0 mm x 0.76 mm. Smart Bay adds USB features to the PC Card.

Card Form Factor
   Card Form Factor:      The form factor describes the size of the card and its pin configuration.
   Your choices are...         
   Type I Card       Type I cards are 54 mm x 85.4 mm, and can be up to 3.3 mm thick. They are commonly used are used as memory cards (RAM, ROM, Flash RAM, etc.). 
   Type II Card       Type II cards are 54 mm x 85.4 mm, and can be up to 5.5 mm thick. They are commonly used in I/O devices such as data/fax modems, and in LAN adapters and non-rotating mass storage devices. 
   Type III Card       Type III cards are 54 mm x 85.4 mm, and can be up to 10.5 mm thick. They are commonly used as hard drives. 
   Type IV Card       Type IV cards have not yet been ratified by the PCMCIA consortium; however, their size is expected to be 54 mm x 85.4 mm with a thickness of 18 mm. They will be used in large capacity hard drives. 
   Other       Other unlisted form factors, such as
  • SmartMedia Card (45mm x 37mm x 0.76mm)
  • CompactFlash (43mm x 36mm x 3.3mm)
  • Miniature Card (38mm x 3.5mm x3.5mm)
  • Solid State Floppy Disk (SSFDC). This is the thinnest and one of the smallest form factor cards (about one-third the size of a credit card)
  • MultiMediaCard (MMC) is approximately the size of a postage stamp.

Operating Modes
   Full Duplex?       Full duplex modems can transmit data in both directions at the same time. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Half Duplex?       Half duplex modems can transmit data in just one direction at a time. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Tone and Pulse Dial?       Tone and pulse dial fax/modems can communicate using a dial pulse or dial tone. A dial pulse is a DC pulse produced by the fax/modem. It interrupts a steady current at a sequence and rate determined by the device's operating characteristics. A dial tone is an electrically-generated, single-frequency oscillation. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Voice/Audio Mode?       Modems with voice/audio mode can be used in either data mode or voice (audio) mode. In data mode, the modem acts like a regular modem. In voice/audio mode, the modem acts like a regular telephone. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
