·Voltage support: 3.3V±5%
Cactus Technologies® CFast card is a high capacity solid-state flash memory product that
complies with the Serial ATA 3.1 standard and is functionally compatible with a SATA hard
disk drive. Cactus Technologies®
CFast cards provide up to 128GB of formatted storage
capacity.
Cactus Technologies® CFast product uses high quality Industrial Grade MLC NAND flash
memory from Kioxia Corporation. In addition, it includes an on-drive intelligent controller
that manages interface protocols, data storage and retrieval as well as ECC, defect handling
and diagnostics, power management, and clock control. The controller’s firmware is
upgradeable, thus allowing feature enhancements and firmware updates while keeping the
BOM stable.

1.1. Supported Standards
Cactus Technologies® CFast card is fully compatible with the following specification:
·ATA 8 Specification published by ANSI
·Serial ATA 3.1 Specification published by the Serial ATA International Organization
·CFast 2.0 Specification published by CFA
1.2. Product Features
Cactus Technologies® Industrial MLC CFast card contains a high level, intelligent controller.
This intelligent controller provides many capabilities including the following:
·Standard ATA register and command set (same as found on most magnetic disk
drives).
·Manages details of erasing and programming flash memory independent of the host
system
·Sophisticated defect managing capabilities (similar to magnetic disk drives).
·Sophisticated system for error recovery using powerful error correction code (ECC).
·Intelligent power management for low power operation.
1.2.1. Host and Technology Independence
Cactus Technologies® Industrial MLC CFast card appears as a standard SATA disk drive to the
host system. The drive utilizes a 512-byte sector which is the same as that in an IDE
magnetic disk drive. To write or read a sector (or multiple sectors), the host computer
software simply issues an ATA Read or Write command to the drive as per the SATA protocol.
The host software then waits for the command to complete. The host system does not get
involved in the details of how the flash memory is erased, programmed or read as this is all
managed by the built-in controller in the drive. Also, with the intelligent on-board controller,
the host system software will not require changing as new flash memory evolves. Thus,
systems that support the Cactus Technologies® Industrial MLC CFast products today will
continue to work with future Cactus Technologies® Industrial MLC CFast cards built with new
flash technology without having to update or change host software.
1.2.2. Defect and Error Management
Cactus Technologies® Industrial MLC CFast card contains a sophisticated defect and error
management system similar to those found in magnetic disk drives. The defect management
is completely transparent to the host and does not consume any user data space.
The soft error rate for Cactus Technologies® Industrial MLC CFast card is much lower than
that of magnetic disk drives. In the extremely rare case where a read error does occur, the
drive has sophisticated ECC to recover the data.
These defect and error management systems, coupled with the solid-state construction, give
Cactus Technologies® Industrial MLC CFast cards unparalleled reliability.
