4 Product Specification
The CFAST TM card is a small form factor non-volatile memory drive which provides high capacity data storage. It
has a standard CFAST connector with SATA and power/control part. The card works at a supply voltage of 3.3V.
The drive with the SATA interface operates in Mode 2.0 (1.5 or 3.0 Gb/s burst).
With an adapter (e.g. Swissbit CFAST Adapter) the drive behaves as a standard SATA disk drive.
The adapter can be mounted in Swissbit 2.5’’ SSD housing.
The drive has an internal intelligent controller which manages interface protocols, data storage and retrieval as
well as hardware BCH-code Error Correction Code (ECC), defect handling, diagnostics and clock control.
The wear leveling mechanism assures an equal usage of the Flash memory cells to extend the life time.
The hardware BCH-code ECC allows to detect and correct 24random bits per double sector or 6 random bits per
sector (depending on the flash type).
The drive has a voltage detector and a powerful power-loss management feature to prevent data corruption
after power-down.
The specification has been realized and approved by the ATA/ATAPI-8 specification.
The system highlights are shown in Table 2 … Table 9.

4.1 Physical description
The CFAST TM card contains a flash controller and Flash memory modules. The controller interfaces with a host
system allowing data to be written to and read from the Flash memory modules.
The CFAST TM card is offered in a Compact Flash size package with a standard CFAST connector with a 7-pin SATA
connector and a 17-pin power and control connector with 15 pins. Figure 6 and Figure 7 show CFAST TM card
dimensions and connector location.
