1. General Description
Apacer CFast 2A-M is the latest enhancement of conventional CFast 2A-M 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 2A-M specifications. CFast 2A-M 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 2A-M card is built with ECC engine correcting up to 40-bit. Together with its small form factor
nature, Apacer CFast 2A-M is definitely the ideal solution to replace conventional PATA-based
CompactFlash for applications in industrial computing systems, mobile computers and video processing
instruments.
