Introduction to PCMCIA Card
What is PCMCIA card?
In computing, the PCMCIA card is a configuration for computer parallel communication peripheral interface for a notebook computer.
The PCMCIA card was originally designed as a standard for memory-expansion cards for computer storage.
It complies with the Japanese JEIDA memory card 4.0 standard.
In October 1992, SanDisk (known as SunDisk at that time) introduced its PCMCIA card.
This had the advantage of increasing the capacity limit to the full 32M available underDOS3.22 on the 95LX.
It also required interrupt features and hot plugging, which required the definition of newBIOSand operating system interfaces.
The card was also used in early digital SLR cameras, such as the Kodak DCS 300 series.
However, their initial use as storage expansion is no longer common.
Some Japanese brand consumer entertainment devices (such as televisions) include a PC card slot for playing media.
Some cards and certain slots can operate at both voltages as needed.
The original standard was built around an enhanced 16-bit ISA bus platform.
The newer version of the PCMCIA standard is CardBus, which is a 32-bit version of the original standard.
Their thickness is 5.0 mm (0.20 inches).
bang out III
bang out III PC card devices are 16-bit or 32-bit.
The thickness of these cards is 16 mm (0.63 inches).
CompactFlash
CompactFlash is a smaller 50-pin subset of the 68-pin PC card interface.
It requires setting the interface mode to memory or ATA Storage.
