What is in This Chapter?
Read this section to familiarize yourself with PC card technology and the 1784-PCC
card. The following table describes what this chapter contains and where to find
specific information.
What is PCMCIA?
The Personal Computer Memory Card International Association (PCMCIA)
developed a standard for credit-card size personal computer (PC) cards. The
PCMCIA standard defines an architecture and communication method for these PC
cards.
PC cards developed under Release 1.0 of the PCMCIA standard are used for data
storage. PC cards developed under Release 2.0 of the PCMCIA standard can be used
for both I/O and data storage.
What is a PC Card?
Since personal computers have become smaller, a need for smaller storage media
developed. The PC card is a small form-factor adapter that can add memory,
storage, and I/O capabilities to these smaller computers.
All PC cards measure the same length and width (54 mm x 85.6 mm), but differ in
thickness at the center. The thickness at the connector end and along the rails is the
same for all types of PC cards.
