APCFAxxxxTAXS-XXDX
1. General Description
CFast emerges as the evolution of the CompactFlash card, by adopting SATA transfer bus rather than
PATA, which delivers a much higher data transfer rate required in industrial and enterprise storage
usages. Although not backward compatible with its former CF form factor, CFast proves to be a more
advanced embedded solution for cache, storage acceleration, communication and networking
applications that require small physical fit.
Apacer CFast is designed with a powerful controller that easily breaks the performance limit for
CompactFlash by delivering the transfer rate up to 160 MB/s while maintaining the reliability and power
efficiency inherited from its former. Leveraging from CompactFlash form factor and SATA interface, CFast
can be integrated into host computing system without excessive BIOS configurations and driver
installations.
In addition to its performance, Apacer CFast is designed with reliability and data integrity. The CFast card
adopts static wear-leveling to average the use of all flash blocks to prolong the lifetime and improve block
efficiency of flash media. A built-in powerful ECC engine operates at hardware level for error correction
and detection. With its well-organized architecture, CFast is an ideal storage device for industrial,
enterprise and mobile applications.
2. Functional Block
Apacer CFast includes a single-chip SATA Controller and the flash media. The controller integrates the
flash management unit to support multi-channel, multi-bank flash arrays. Figure 2-1 shows the functional
block diagram.
