`PC Card Technology Primer
`
`Introduction
`
`In the early 90's, the rapid growt h of
`mobile comput ing drove t he development
`of smaller, lighter, and more portable
`tools for informat ion processing. One of
`t he most exciting of these innovat ions
`was PC Card technology. The power and
`versati lity of PC Cards quickly made them
`standard equipment in mobile computers.
`The rapid development and worldwide
`adopt ion of PC Card t echnology has been
`due in large pa rt to t he standards efforts
`of the Personal Comput er Memory Card
`International Associat ion (PCMCIA) .

`The associat ion's PC Card St andard is now bringing t he benefits of
`t hese same PC Cards to a variety of indust ries and vert ical
`applicat ions, including sma rt cards, set-top boxes, automobi les,
`and others. The PC Card technology's compact size and
`ruggedness make it t he ideal t echnology for a wide variety of
`applicat ions.

`
`Card Types versus Release Numbers
`
`The PC Card Standard provides physical specificat ions for t hree
`types of PC Cards, with additional provisions for extended cards.
`All t hree card types measure the same length and widt h and use
`t he same 68-pin connector. The only difference between the card
`types is t hickness. The thicknesses are 3.3, 5.0, and 10.5
`m illimeters for Type I, Type II, and Type III cards respect ively.
`Because t hey differ only in t hickness, a thinner card can be used
`in a t hicker slot , but a t hicker card can not be used in a t hinner
`slot.
`
`The card types each have feat ures t hat fit the needs of different
`applicat ions. Type I PC Cards are typically used for memory
`devices such as RAM, Flash, OTP, and SRAM cards. Type II PC
`Cards are typically used for I/ O devices such as data/ fax modems,
`LANs, and mass storage devices. Type III PC Cards are used for
`devices whose components are thicker, such as rotating mass
`storage devices. Extended cards allow t he addition of components
`t hat must remain outside t he system for proper operation, such as
`antennas for wireless applicat ions.

`PCMCIA standard Re lease 1.0/ JEIDA 4.0 - June 1990
`
`The first release of the standard defined t he 68-pin interface and
`t he Type I and Type II PC Card form factors. The initial release of
`t he PCMCIA Standard specified the electrical and physical
`requirements for memory cards only. It defined t he Metaformat or
`Card Information Struct ure (CIS) t hat is critical to interoperability
`and plug-and-play for PC Cards . There was no concept of
`input/out put (I/O) cards in t he first release of t he PC card
`St andard .
`
`PCMCIA standard, Releases 2.0, 2.01 and 2.1 - 1991-1994
`
`The second release of the standard defined an I/ O interface for
`t he same 68-pin interface as was used for the PCMCIA memory
`cards in the first release of the Standard. Release 2.0 also added
`various clarifications to the first release, support for dual-voltage
`memory cards, and sections dealing with card environmental
`requirements and test met hods. Release 2.01 added t he PC
`CardATA specification, the Type III card type, and t he Auto(cid:173)
`Indexing Mass Storage (AIMS) specificat ion geared toward digita l
`images was also added . It also included the init ia l version of the
`Card Services Specificat ion. Release 2.1 further enhanced t he
`Card and Socket Services Specificaiton, and made improvements
`to the card Information Structure.
`
`PC Card Standard-February 1995
`
`The latest release of t he PC Card Standard added information to
`improve compat ibility and added support for feat ures such as 3.3
`volt operation, OMA support, and 32-bit CardBus busmastering.

`
`About Compatibility
`
`The rapid rate of adopt ion of PC Card slots has driven a steady
`stream of card and host implementat ions. During t hat t ime, PC
`Cards containing new technologies were introduced and significant
`new capabi lit ies were added to t he Standard. At the same time
`considerable experience was gained by card, host, and software
`vendors, and opport unities t o improve compatibility were
`recognized.
`
`PCMCIA's goa l is to make t he technology as easy to use as
`possible, however, the Standard can only provide guidelines in
`some areas so t here will be manufacturers who do not follow the
`St andard exactly or have interpret ed it differently. Therefore,
`development planned for f lexibility and adaptability will allow for
`t he greatest compat ibility. One way t o be prepared for the variety
`of the real world is to perform exhaustive test ing of designs wit h
`all the significant components from soft ware functions and
`modules to entire platforms.
`
`During the last year, t here have been three maj or factors that
`have come together to great ly improve PC Card interoperability.
`In the March 1995 release of the standard, t he software
`specification for PC Cards were improved in a number of ways.

`
`In addition, increasing cooperation between card, host and
`software developers within the industry has resulted in improved
`interoperabi lity. Towards this end, PCMCIA and the Plug and Play

`
`Features of PC Card Technology
`
`A Detailed Overview of the PC Card Standard
`
`Card Information structure - The CIS describes the
`characteristics and capabilities of the card so the host system can
`automatically configure it. CIS is defined in the Metaformat
`Specification.
`
`CardBys - cardBus allows allows PC Cards and hosts to use 32-bit
`busmastering and to operate at speeds up to 33MHz.
`!!HA - The Standard allows cards to utilize Direct Memory Access
`technology directly in the hardware when matched with a
`corresponding host system.
`
`execute In Place (XIP) - Allows operating system and
`application software to run directly from the PC Card, eliminating
`the need for large amounts of system RAM.
`
`Low Voltage Operation - The Standard enables 3.3 and 5 volt
`operation. A physical keying mechanism for 3.3 volt cards
`protects them from being damaged in a 5 volt slot.
`
`Multiple Function PC Cards - The Standard enables truly
`standardized multiple function PC-cards.
`
`Plug and Play - PC Cards can be inserted or removed while the
`system is on because power and ground contact pins are the
`longest contacts, ensuring that disconnect signa ls disengage first,
`preserving data integrity.
`
`Power Management - The Standard provides a means to
`interface to APM (Advanced Power Management) through the Card
`Services Specification.
`
`Zoomed Video (ZVl - Zoomed Video is a connection between a
`PC Card and host system that allows the card to write video data
`directly to the VGA controller. The data is transferred with no
`buffering requirements because it is transferred over the ZV bus
`and not the system bus.
