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 64GB of formatted storage capacity.
Cactus Technologies® CFast product uses high quality industrial grade MLC NAND flash memory from Kioxia Corporation, operating in true Psuedo-SLC mode (i.e. not Fast-page mode), with enhanced endurance and performance over standard MLC NAND. 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.
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
Product Features
Cactus Technologies® Industrial pSLC 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.
Host and Technology Independence
Cactus Technologies® Industrial pSLC 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 pSLC CFast products today will continue to work with future Cactus Technologies® Industrial pSLC CFast cards built with new flash technology without having to update or change host software.
Defect and Error Management
Cactus Technologies® Industrial pSLC 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 pSLC 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 pSLC CFast cards unparalleled reliability.

AC Characteristics
Cactus Technologies® CFast products conforms to all AC timing requirements as specified in the CFA specifications. Please refer to that document for details of AC timing for all operation modes of the device.
ATA Drive Register Set Definition and Protocol
The communication to or from the CFast card is done using FIS. Legacy ATA protocol is supported by using the legacy mode defined in the SATA specifications. In this mode, the FIS has defined fields which provide all the necessary ATA task file registers for control and status information. The Serial ATA interface does not support Primary/Secondary or Master/Slave configurations. Each SATA channel supports only one SATA device, with the register selection as defined by the ATA standard.
ATA Task File Definitions
The following sections describes the usage of the ATA task file registers. Note that the Alternate Status Register of legacy ATA is not defined for SATA drives.
Data Register
The Data Register is a 16-bit register, and it is used to transfer data blocks between the SSD data buffer and the Host.
Error Register
This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. The bits are defined as follows:
D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
---|---|---|---|---|---|---|---|
BBK | UNC | 0 | IDNF | 0 | ABRT | 0 | AMNF |
Bit 7 (BBK) This bit is set when a Bad Block is detected.
Bit 6 (UNC) This bit is set when an Uncorrectable Error is encountered.
Bit 5 This bit is 0.
Bit 4 (IDNF) The requested sector ID is in error or cannot be found.
Bit 3 This bit is 0.
Bit 2 (Abort) This bit is set if the command has been aborted because of
a status condition: (Not
Ready, Write Fault, etc.) or when an invalid command has been issued.
Bit 1 This bit is 0.
Bit 0 (AMNF) This bit is set in case of a general error.
Feature Register
This register provides information regarding features of the SSD that the host can utilize.
Sector Count Register
This register contains the number of sectors of data requested to be transferred on a read or write operation between the host and the SSD. If the value in this register is zero, a count of 256 sectors is specified. If the command was successful, this register is zero at command completion. If not successfully completed, the register contains the number of sectors that need to be transferred in order to complete the request.
Sector Number (LBA 7-0) Register
This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any SSD data access for the subsequent command.
Cylinder Low (LBA 15-8) Register
This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the Logical Block Address.
Cylinder High (LBA 23-16) Register
This register contains the high order bits of the starting cylinder address or bits 23-16 of the Logical Block Address.
Drive/Head (LBA 27-24) Register
The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing instead of cylinder/head/sector addressing. The bits are defined as follows:
D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
---|---|---|---|---|---|---|---|
1 | LBA | 1 | DRV | HS3 | HS2 | HS1 | HS0 |
Bit 7 This bit is set to 1.
Bit 6 LBA is a flag to select either Cylinder/Head/Sector (CHS) or
Logical Block Address Mode (LBA).
When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block
Address is
selected. In Logical Block Mode, the Logical Block Address is interpreted as
follows:
LBA07- LBA00: Sector Number Register D7-D0.
LBA15- LBA08: Cylinder Low Register D7-D0.
LBA23- LBA16: Cylinder High Register D7-D0.
LBA27- LBA24: Drive/Head Register bits HS3-HS0.
Bit 5 This bit is set to 1.
Bit 4 (DRV) DRV is the drive number. This should always be set to 0.
Bit 3 (HS3) When operating in the Cylinder, Head, Sector mode, this is
bit 3 of the head number. It
is Bit 27 in the Logical Block Address mode.
Bit 2 (HS2) When operating in the Cylinder, Head, Sector mode, this is
bit 2 of the head number. It
is Bit 26 in the Logical Block Address mode.
Bit 1 (HS1) When operating in the Cylinder, Head, Sector mode, this is
bit 1 of the head number. It
is Bit 25 in the Logical Block Address mode.
Bit 0 (HS0) When operating in the Cylinder, Head, Sector mode, this is
bit 0 of the head number. It
is Bit 24 in the Logical Block Address mode.
Status Registers
These registers return the status when read by the host. Reading the Status register does clear a pending interrupt while reading the Auxiliary Status register does not. The meaning of the status bits are described as follows:
D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
---|---|---|---|---|---|---|---|
BUSY | RDY | DWF | DSC | DRQ | CORR | 0 | ERR |
Bit 7 (BUSY) The busy bit is set when the device has access to the
command buffer and registers and the host is locked out from accessing the
command register and buffer. No other bits in this register are valid when
this bit is set to a 1.
Bit 6 (RDY) RDY indicates whether the device is capable of performing
operations requested by the host. This bit is cleared at power up and remains
cleared until the device is ready to accept a command.
Bit 5 (DWF) This bit, if set, indicates a write fault has occurred.
Bit 4 (DSC) This bit is set when the device is ready.
Bit 3 (DRQ) The Data Request is set when the device requires that
information be transferred
either to or from the host through the Data register.
Bit 2 (CORR) This bit is set when a Correctable data error has been
encountered and the data has
been corrected. This condition does not terminate a multi-sector read
operation.
Bit 1 (IDX) This bit is always set to 0.
Bit 0 (ERR) This bit is set when the previous command has ended in some
type of error. The bits in
the Error register contain additional information describing the error.
Device Control Register
This register is used to control the drive interrupt request and to issue an ATA soft reset to the drive. The bits are defined as follows:
D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
---|---|---|---|---|---|---|---|
HOB | X | X | X | 1 | SW Rst | -IEn | 0 |
Bit 7 This bit is used in 48-bit addressing mode. When cleared, the host
can read the most recently written values of the Sector Count,Drive/Head and
LBA registers. When set, the host will read the previous written values of
these registers. A write to any Command block register will clear this bit.
Bit 6 This bit is an X (Do not care).
Bit 5 This bit is an X (Do not care).
Bit 4 This bit is an X (Do not care).
Bit 3 This bit is ignored by the drive.
Bit 2 (SW Rst)This bit is set to 1 in order to force the drive to perform
an AT Disk controller Soft
Reset operation. The drive remains in Reset until this bit is reset to ‘0’.
Bit 1 (-IEn) The Interrupt Enable bit enables interrupts when the bit is 0.
When the bit is 1, interrupts from the drive are disabled. This bit is set to
0 at power on and Reset.
Bit 0 This bit is ignored by the drive.
Drive Address Register
This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host’s I/O space because of potential conflicts on Bit 7. The bits are defined as follows:
D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
---|---|---|---|---|---|---|---|
X | -WTG | -HS3 | -HS2 | -HS1 | -HS0 | -nDS1 | -nDS0 |
Bit 7 This bit is unknown.
Implementation Note:
Conflicts may occur on the host data bus when this bit is provided by a Floppy
Disk Controller operating at the same addresses as the SSD. Following are some
possible solutions to this problem:
- Locate the SSD at a non-conflicting address (i.e., Secondary address (377) when a Floppy Disk Controller is located at the Primary addresses).
- Do not install a Floppy and a SSD in the system at the same time.
- Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7/377 when a SSD product is installed and conversely to tri-state D6-D0 of I/O address 3F7/377 when a floppy controller is installed.
- Do not use the SSD’s Drive Address register. This may be accomplished by either a) If possible, program the host adapter to enable only I/O addresses 1F0-1F7, 3F6 (or 170- 177, 176) to the SSD or b) if provided use an additional Primary/Secondary configuration in the SSD that does not respond to accesses to I/O locations 3F7 and 377. With either of these implementations, the host software must not attempt to use information in the Drive Address Register.
Bit 6 (-WTG) This bit is 0 when a write operation is in progress,
otherwise, it is 1.
Bit 5 (-HS3) This bit is the negation of bit 3 in the Drive/Head
register.
Bit 4 (-HS2) This bit is the negation of bit 2 in the Drive/Head
register.
Bit 3 (-HS1) This bit is the negation of bit 1 in the Drive/Head
register.
Bit 2 (-HS0) This bit is the negation of bit 0 in the Drive/Head
register.
Bit 1 (-nDS1) This bit is 0 when drive 1 is active and selected.
Bit 0 (-nDS0) This bit is 0 when the drive 0 is active and selected.

Write Protect Feature
Cactus Technologies® -245 Series CFast card supports optional Write Protect function using a physical write protect switch. When the switch is toggled to the WP position, the card is write protected. The setting of the switch is sensed only during power up time, changing the setting of this switch after power up will not alter the write protect behavior. However, to avoid any unintended side effects, it is recommended that this switch not be toggled when power is applied to the card.
When the write protect function is enabled, all data write commands to the card will be accepted but the write data will be silently discarded. The card will follow all the data transfer handshake and will return successful status to the host. This method of handling write protection provides the best compatibility to host systems as simply rejecting write commands and returning error status may cause some operating systems to hang.
