1. General Descriptions
Apacer SM220-CFast 2.0 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 consists of SATA-based 7-pin signal segment and 17-pin for power and
control purposes. For data efficiency, the internal controlling unit of the SM220-CFast 2.0 is
engineered with DRAM for enhanced random performance which achieves data transfer rates up to
540 MB/s in sequential access and 76,000 IOPS in 4KB random access. In addiation, Apacer CFast
cards come with S.M.A.R.T. for lifetime monitoring and customization support if write protection is
required. Apacer SM220-CFast 2.0 guarantees reliability of applications in harsh environments by
implementing intelligent Flash Management algorithms and Error Correction.
2. Functional Block
Apacer SM220-CFast 2.0 includes a single-chip SATA 6.0 Gbps 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.
