CFast 2 STD
AP-CFAxxxxACXN-XAT
1. General Description
Apacer CFast 2 STD is the latest enhancement of conventional CFast form factor that delivers various
technological advantages. This new flash memory card comes with SATA 6.0 Gbps interface for higher
performance and is compliant with standard CFast specifications. CFast 2 STD consists of SATA-based
7-pin signal segment and 17-pin for power and control purposes. It can offer moderate capacity and
decent data transfer performance. For power efficiency, this new flash memory card leverages the
technological benefits of SATA Revision 3.1 specifications, including Device Sleep. That will greatly
reduce power consumption when the device is not in operating mode. For data integrity, the CFast card is
built with ECC engine correcting up to 40-bit. Together with its small form factor nature, Apacer CFast 2
STD is definitely the ideal solution to replace conventional PATA-based CompactFlash for applications in
industrial computing systems, mobile computers and video processing instruments.
2. Functional Block
Apacer CFast 2 STD includes a single-chip SATA 6.0 Gbbps 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.
