CFast

APCFAxxxxQAHS-XXDCM

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 II 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.
