CE-ATA
Consumer Electronics ATA (CE-ATA) is an interface standard for the connection of storage devices and hosts in consumer electronic device such as mobile and handheld devices. One of the primary goals is to standardize connections for small form factor hard disk drives such as 1-inch Microdrives. The standard is maintained bCE-ATA Workgroup History The CE-ATA Specification was developed in 2005. Interface MMC CE-ATA is electrically and physically compatible with MMC specification. CE-ATA uses MMC connector on host devices and matching flex cable or circuit connection on CE-ATA hard disk drives. Pin Assignment {, class="wikitable" border="1" style="text-align: center;" , - !

Multimedia Card
The MultiMediaCard, officially abbreviated as MMC, is a memory card standard used for solid-state storage. Unveiled in 1997 by SanDisk and Siemens, MMC is based on a surface-contact low pin-count serial interface using a single memory stack substrate assembly, and is therefore much smaller than earlier systems based on high pin-count parallel interfaces using traditional surface-mount assembly such as CompactFlash. Both products were initially introduced using SanDisk NOR-based flash technology. MMC is about the size of a postage stamp: 32 mm × 24 mm × 1.4 mm. MMC originally used a 1-bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time. MMC can be used in many devices that can use Secure Digital (SD) cards. Typically, an MMC operates as a storage medium for devices, in a form that can easily be removed for access by a PC via a connected MMC reader. Modern computers, both laptops and desktops, often have SD slot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AT Attachment
Parallel ATA (PATA), originally , also known as IDE, is a standard interface designed for IBM PC-compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives. The connection is used for storage devices such as hard disk drives, floppy disk drives, and optical disc drives in computers. The standard is maintained by the X3/INCITS committee. It uses the underlying (ATA) and Packet Interface ( ATAPI) standards. The Parallel ATA standard is the result of a long history of incremental technical development, which began with the original AT Attachment interface, developed for use in early PC AT equipment. The ATA interface itself evolved in several stages from Western Digital's original Integrated Drive Electronics (IDE) interface. As a result, many near-synonyms for ATA/ATAPI and its previous incarnations are still in common informal use, in particular Extended IDE (EIDE) and Ultra ATA (UATA). After the intr ...
