Cactus Technologies® Industrial pSLC mSATA SSD 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® Industrial pSLC mSATA SSD provides up to 256GB of formatted storage capacity.
Cactus Technologies® Industrial pSLC mSATA SSD 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® mSATA SSD is fully compatible with the following specification:

• ATA 8/ACS2 Specification published by ANSI
• Serial ATA 3.1 Specification published by the Serial ATA International Organization

Product Features
Cactus Technologies® Industrial pSLC mSATA SSD 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. Host and Technology Independence
   Cactus Technologies® Industrial pSLC mSATA SSD 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 mSATA SSD products today will continue to work with future Cactus Technologies® Industrial pSLC mSATA SSDs built with new flash technology without having to update or change host software.

2. Defect and Error Management
   Cactus Technologies® Industrial pSLC mSATA SSD 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 mSATA SSD 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 mSATA SSDs unparalleled reliability.

3. Power Supply Requirements
   Cactus Technologies® Industrial pSLC mSATA SSD operates at a voltage range of 3.3 volts ± 5%.

ATA Drive Register Set Definition and Protocol

The communication to or from the SSD 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.

1. 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.

2. 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

3. Feature Register
   This register provides information regarding features of the SSD that the host can utilize.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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

9. 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:

10. 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

11. 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
