Learn About the History of PCMCIA CardBus to ExpressCard
PCMCIA is a "PERSONAL COMPUTER MEMORY CARD INTERNATIONAL ASSOCIATION" abbreviation, PCMCIA defines three different types of cards, which PCMCIA (PC Memory Card International Association of Machine abbreviation) is a more than 300 member companies of the International Standards Organization and Trade Association, the organization was founded in 1989, the aim of establishing an international standard integrated circuits to improve the interchangeability of mobile computers. Such computers require high strength, low energy consumption, small size, but a few properties of this very demanding. As the demand for mobile computer users has changed, so the standard PC card accordingly changed. In 1991, PCMCIA memory cards used in the definition of the original 68 foot I / O connectivity standard lines. Aware of the software manufacturers need to increase the compatibility, and therefore this criterion also has been a corresponding application.
In recent years, PCMCIA Organization has recognized the increased demand for high-speed applications. Therefore, the formulation of the CardBus and Zoomed Video specification allows MPEG video and 10Mbit Ethernet to high speed. Because the speed continues to increase, PCMCIA also has been added to this specification, thus increasing compatibility and taking into account a number of other aspects of mobile machines, such as the 3.3V operation and power management.
And Now,a new kind of laptop adapter card make out. That is Expresscard. The PCMCIA to Expresscard Adapter quickly and easily adapts USB-Based ExpressCard/34 devices to work through your laptop CardBus slot.With support for hot-plug installation, you can connect and remove the CardBus to ExpressCard adapter without shutting down the computer, making it the ideal solution for connecting commonly used devices such as broadband wireless modems, flash card adapters and other devices. This adapter allows USB-based ExpressCard/34 devices such as Memory Card readers, TV Tuners and WiFi adapters to be connected to your notebook via its PC card slot.
As if Expresscard has became more and more popular,so the demand for ExpressCard To PCMCIA Adapter increases rapidly. Today, PCMCIA-CardBus not only promoted a removable PC card inside the computer the ability to work together, but also of many other products to improve the ability to work together, such as digital cameras, cable TV, set-top boxes and cars. As the demand for modular peripherals product range has increased, so that many of the compatibility of peripherals also increased. Therefore, PCMCIA has recently changed its mission thus: "the development of standards for modular peripherals to facilitate the application in the world."
The new task PCMCIA is a small structure of a typical sub-card standard. PCMCIA in the original PC card standard based on the increase of small-scale structure of sub-PC-card standard, and now PCMCIA applications have been published and in the maintenance of mini-card standard. In addition, PCMCIA Smart Media Card upcoming standard, which has the smallest of today's modular peripherals provide a memory structure solution.

PCMCIA defines three different types of cards, their length and width is 85.6 × 54mm, but differs in thickness. Type I was the first PC card, 3.3mm thick is mainly used for RAM and ROM; Type II will increase the thickness of 5.5mm is also greatly expanded the scope of application, including most of the modem (modem), and faxmodem (fax modem), LAN Adapter and other electrical equipment; Type III is further increased to a thickness of 10.5mm this PC Card is mainly used for rotating storage devices (such as hard disk).
