The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots. The cards contain electronic circuits and sometimes connectors for external devices. The ExpressCard standard replaces the PC Card (also known as PCMCIA) standards.ExpressCards can connect a variety of devices to a computer including mobile broadband modems (sometimes called connect cards), IEEE 1394 (FireWire) connectors, USB connectors, Ethernet network ports, Serial ATA storage devices, solid-state drives, external enclosures for desktop-size PCI Express graphics cards and other peripheral devices, wireless network interface controllers (NIC), TV tuner cards, Common Access Card (CAC) readers, and sound cards.

    Standards

    Originally developed by the Personal Computer Memory Card International Association (PCMCIA), the ExpressCard standard is maintained by the USB Implementers Forum (USB-IF). The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed)WEB,weblink ExpressCard, USB.org, 2013-05-09,weblink" title="web.archive.org/web/20140625130909weblink">weblink 2014-06-25, dead, (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes. The cards are hot-pluggable. The ExpressCard standard is an open standard by ITU-T definition, and can be obtained from the USB-IF website free of charge.WEB,weblink ExpressCard_specs, USB.org, 2013-05-09,weblink" title="web.archive.org/web/20140814032847weblink">weblink 2014-08-14, dead, USB-IF administers the ExpressCard Compliance Program, under which companies earn the right to obtain a license to use the ExpressCard logo on their compliant products.WEB,weblink ExpressCard Compliance, USB.org, 2013-05-09,

    {{anchor|Express34|Express54}}Form factors

    File:PCCard-ExpressCard ZP.svg|right|thumb|upright|ExpressCards compared to the predecessor PC CardPC CardThe ExpressCard standard specifies two form factors, ExpressCard/34 ({{Convert|34|mm}} wide) and ExpressCard/54 ({{Convert|54|mm|abbr = on}} wide, in an L-shape)—the connector is the same on both (34 mm wide). Standard cards are {{Convert|75|mm|abbr = on}} long ({{Convert|10.6|mm|abbr = on}} shorter than CardBus) and {{Convert|5|mm|abbr = on}} thick, but may be thicker on sections that extend outside the standard form for antennas, sockets, etc. With its 75 mm standard length, the ExpressCard will protrude 5 mm over the holder's surface (e.g. laptop surface), whereas a variant with 70 mm length remains level with the surface.

    Comparison to other standards

    (File:Cardbus to ExpressCard Adapter.jpg|thumb|left|140px|Cardbus to ExpressCard Adapter)The older PC Cards came in 16-bit and the later 32-bit CardBus designs. The major benefit of the ExpressCard over the PC card is more bandwidth, due to the ExpressCard's direct connection to the system bus over a PCI Express ×1 lane and USB 2.0, while CardBus cards only interface with PCI. The ExpressCard has a maximum throughput of 2.5 Gbit/s through PCI Express and 480 Mbit/s through USB 2.0 dedicated for each slot, while all CardBus and PCI devices connected to a computer usually share a total 1.06 Gbit/s bandwidth.The ExpressCard standard specifies voltages of either 1.5 V or 3.3 V; CardBus slots can use 3.3 V or 5.0 V. The ExpressCard FAQ claims lower cost, better scalability, and better integration with motherboard chipset technology than Cardbus. PCMCIA devices can be connected to an ExpressCard slot via an adapter.When the PC Card was introduced, the only other way to connect peripherals to a laptop computer was via RS-232 and parallel ports of limited performance, so it was widely adopted for many peripherals. More recently, virtually all laptop equipment has 480 Mbit/s Hi-Speed USB 2.0 ports, and most types of peripheral which formerly used a PC Card connection are available for USB or are built-in, making the ExpressCard less necessary than the PC Card was in its day. Some laptop computers do not have an ExpressCard slot.

    • Overam integrates an ExpressCard slot in its Mirage 7283 and 9570 laptops.{{Update inline|date=January 2021}}
    Because of the lack of backward compatibility, some laptop manufacturers initially released models incorporating both CardBus (PCMCIA, PC Card) and ExpressCard slots. These included certain models of Acer Aspire, Acer Extensa, Toshiba Satellite, Dell Latitude and Precision, MSI S42x and Lenovo ThinkPad Z60m, R52, T60, R61 and T61.In March 2005, the Personal Computer Memory Card International Association (PCMCIA) showed some of the first ExpressCard products at the CeBIT trade show in Germany.NEWS, CeBIT : Faster ExpressCards on tap for PC expansion media,weblink A large number of ExpressCard devices were presented.NEWS, XGI at CeBIT 2005 Hanover Computer Fair!,weblink NEWS, Trade Show Information,weblink NEWS, XGI A Shining Spotlight at CeBIT 2005 Hanover Computer Fair!,weblink NEWS, TechPowerUp CeBIT 2005 - Day 1,weblink NEWS, TechPowerUp CeBIT 2005 - Day 2,weblink NEWS, NVIDIA Expands GPU Technology Lead with the Introduction of Two New GeForce 6 Series GPUs,weblink NEWS, SiS to show new products at CeBIT 2005,weblink NEWS, XGI at CeBIT 2005 Hanover Computer Fair!,weblink NEWS, VIA Technology Showcase at CeBIT 2005,weblink 2014-05-27,weblink" title="web.archive.org/web/20140827075436weblink">weblink 2014-08-27, dead, NEWS, CeBIT Hannover 2005 (Part 1) New Motherboards at ECS,weblink NEWS, New ATI and SiS Chipsets, NEC Dual-Layer DVD, More ATI news from CeBIT 2005,weblink In November 2006, Belkin announced that it was launching the first ExpressCard docking station, which uses the PCIe part of an ExpressCard connection to enable 1600x1200 video and the USB part to provide USB, audio and network ports.WEB,weblink Press Room | Belkin USA Site, Belkin.com, 2013-05-09,weblink" title="web.archive.org/web/20071012172303weblink">weblink 2007-10-12, dead, WEB,weblink Belkin : High Speed Docking Station, 2007-03-09, dead,weblink" title="web.archive.org/web/20070305201728weblink">weblink 2007-03-05, This points to the ability for ExpressCard to allow more capable non-OEM docking stations for laptop computers.In 2007, Sony introduced its Vaio TZ model, which incorporates ExpressCards. Also the Sony Vaio FZ and Vaio Z series have the ExpressCard/34 Slot integrated in them. Sony also uses the ExpressCard/34 form factor for the flash memory modules in its XDCAM EX/SxS based camcorders, making the copying of video data between these cameras and ExpressCard-equipped laptops easier. For this reason, Sony also offers a USB-based SxS reader for desktop computers.The Toshiba Satellite P and X 200/205 series of laptops and desktop replacements have an ExpressCard/34 slot since April 2007.{{citation needed|reason=It seems Satellite P840 has no ExpressCard.|date=October 2012}} In P200 series it's a /54 size not /34.WEB,weblink Manuals - Dynabook, Ever since PCMCIA disbanded in 2009, newer laptops from 2010 on more commonly do not include ExpressCard slots except for some business-oriented models (e.g. some Lenovo models use it for supporting a smart card reader).WEB, 13 Disappearing Laptop Ports and How to Get Them Back,weblink Piltch, Avram, 2016-09-26, LaptopMag, en, 2020-05-22, For WWAN connectivity cards, either mini-PCIe slots or USB connected variants have become the preferred connection methods. For external desktop graphics card enclosures and other peripherals that interface with PCI Express, Thunderbolt has supplanted ExpressCard in that role due to its faster speed and ability to use multiple PCIe 2.0 lanes; the first and second Thunderbolt revisions offered 20 Gbit/s of maximum bandwidth with four PCIe 2.0 lanes while ExpressCard could only muster 5 Gbit/s maximum with one PCIe 2.0 lane.WEB, Review External Graphics Cards for Laptops,weblink Ricchizzi, Nino, 2014-03-01, Notebookcheck, en, 2020-05-22, WEB, Expresscard 2.0 eGPUs - pros, cons and candidate notebooks,weblink 2017-02-18, eGPU.io, en-US, 2020-05-22,

    ExpressCard 2.0

    The ExpressCard 2.0 standard was introduced on March 4, 2009, at CeBIT in Hannover. It provides a single PCIe 1.0 2.5 GT/s lane (optionally PCIe 2.0 with 5 GT/s) and a USB 3.0 "SuperSpeed" link with a raw transfer speed of 5 Gbit/s (effective transfer speed up to 400 MB/s).WEB,weblink PCI Express 3.0 Frequently Asked Questions, PCI-SIG, 18 February 2010, 1 February 2014,weblink" title="web.archive.org/web/20140201172536weblink">weblink dead, ExpressCard 2.0 FAQ {{webarchive|url=https://web.archive.org/web/20091229193114weblink |date=2009-12-29 }} (pdf) at ExpressCard.org, accessed 2009-12-04. It is forward and backward compatible with earlier ExpressCard modules and slots. USB 3.0 SuperSpeed compatibility is achieved by sharing the pins with the PCIe link.
