The CompactFlash Association (CFA) recently released revision 1.0 of the CFast specification. The current CompactFlash PATA (parallel ATA) interface provides up to a 133MB/second interface data rate. The SATA interface will provide interface data rates up to 3Gb/sec as well as compatibility with the SATA disk drive interfaces that are increasingly being used.
The CF+ & CompactFlash and CFast standards ensure that today’s and tomorrow’s embedded systems, single board computers, multi-mega pixel DSLR cameras, and other devices will be compatible with faster and even higher capacity CF and CFast cards, as they become available.
CompactFlash cards are currently available up to 48GB with sustained data rates of 45MB/sec. and provide the dominant SSD flash storage solution for embedded systems, single board computers, multi-mega pixel DSLR cameras, and other devices.
In addition to CompactFlash data storage cards, there are CF cards that provide I/O capability. VGA, Ethernet, modem, serial, parallel, digital phone, GSM, Bluetooth, Ethernet wireless, wand & laser barcode scanners, finger print scanners, TV and GPS CF+ cards are all available.
