Product Introduction
Wintec 2.5” SATA II SSD JM612 Series
WxSSxxxG1TA-J2xx
The Wintec Industries WxSSxxxG1TA-J2xx series of ROHS Compliant
Solid State drives are constructed with NAND-type flash memory
devices paired to JMicron JMF612 SSD controller for virtual-tophysical address mapping and other sophisticated flash
management functions. The Wintec Flash Solid State Disk (SSD)
provides major advantages over the traditional magnetic hard disk
drive (HDD). Faster access time and transfer rate, silent operation
and low power consumption, better shock and vibration resistance,
and lower total cost of ownership make the Wintec SSDs an
attractive choice as the next generation mass storage device.
The Wintec JM612 series SSD provides high-speed data transfer
and reliability utilizing SLC or MLC NAND flash in storage capacities
ranging from 16GB to 256GB, in a small 2.5” hard drive form factor.
Its robust design enables the SSD to achieve highest reliability and
performance.
The JMF612 controller implements bad block management and
dynamic/static wear-leveling techniques to ensure that the NAND
flash memory is not worn out prematurely. The drive supports 24
bits/1K Byte sector BCH ECC algorithm for error correction. The
drive supports basic S.M.A.R.T features to monitor the drive status
and TRIM command to efficiently maintain the data.
The Wintec JM612 series SSD drives are ideal for Desktop
computers, notebooks and low to mid end server systems that
need performance and reliability.

Figure 1: Block Diagram
The Wintec JM612 series SSD utilizes a flash controller chip with 8 parallel channels of flash memory interface. The flash controller also
simultaneously manages the file read and write interface with the host system via a single SATA-II interface. By utilizing 8 parallel
channels of MLC flash memory, the Wintec SSD can provide both high performance and reliability, while maintaining a minimal unit cost.
1.3 Flash Cell Wear Leveling
The SSD controller tracks the number of PE (program/erase) cycles that each block in the SSD goes through, and will dynamically remap
logical sectors written from the host to different physical pages and blocks within the NAND flash. This including with static wear leveling
ensures the flash cells wear evenly, and no premature wear out or data loss will occur in any portions of the drive.
1.4 ECC Correction
The drive supports BCH error correction code; the controller can correct 16 bits or 24 bits per 1024 byte data.
1.5 TRIM
The JM612 series SSD supports the TRIM command. Data that has been deleted from the host can be marked as free space
by the host issuing the TRIM command to the drive. This allows the drive to more efficiently reclaim free space and
maintain performance.

2.2 SATA Pin Assignment and Description
The SATA connectors are compliant with standard SATA power specifications. As is standard, power may be supplied to all of the power
pins. However, only the 5V power pins are utilized to provide power to the SSD. Therefore, where non-standard power supplies and
connections are utilized, the power supply does not need to supply the SSD with power to the 3.3V or 12V power pins.

SMART Command Support
3.2.1 SMART Function Set (B0h)
The JM612 series drive performs different processing required for predicting device failures, according to the subcommand specified in
the feature register. If the feature register contains an unsupported value, the aborted command error is returned. If the SMART function
is disabled, any subcommand other than SMART enable operations results in the aborted command error.

3.2.5 SMART Enable/Disable Attribute Auto Save (B0h/D2h)
This command enables and disables the optional attribute autosave feature of the device. This command may either allow the device,
after some vendor specified event, to save the device updated attributes to non-volatile memory; or this command may cause the
autosave feature to be disabled. The state of the attribute autosave feature, either enabled or disabled, shall be preserved by the device
during all power and reset events.
A value of zero written by the host into the devices count field before issuing this command shall cause this feature to be disabled.
Disabling this feature does not preclude the device from saving SMART data to no-volatile memory during some other normal operation
(e.g., during a power-on or power-off sequence or during an error recovery sequence).
A value of F1h written by the host into the device’s count field before issuing this command shall cause this feature to be enabled. Any
other non-zero value written by the host into this field before issuing this command is vendor specific. The meaning of any non-zero value
written to this field at this time shall be preserved by the device during all power and reset events.
3.2.6 SMART Enable/Disable Attribute Auto Save (B0h/D2h)
Saves any modified attribute values
3.2.7 SMART Execute Off-line Immediate (B0h/D4h)
This command of non-data input causes the controller to immediately initiate the set of activities that collect SMART data in off-line
mode and then save data to the NAND flash memory, or execute a self-diagnostic test routine in either captive or off-line mode.

3.2.8 SMART Read Log (B0h/D5h)
This command returns the indicated log sector contents to the host.
Sector count specifies the number of sectors to be read from the specified log. The log transferred by the drive shall start at the first
sector in the specified log, regardless of the sector count requested. Sector number indicates the log sector to be returned as described in
the following Table.

3.2.9 SMART Write Log (B0h/D6h)
This command writes as indicated number of 512 byte data sectors to the indicated log (Host vendor specific).
3.2.10 SMART Enable Operations (B0h/D8h)
Enables the SMART function; this setting is maintained when the power is turned off and then back on. Once the SMART
function is enabled, subsequent SMART ENABLE OPERATIONS commands do not affect any parameters.
3.2.11 SMART Disable Operations (B0h/D9h)
Disables the SMART function; upon receiving the command, the drive disables all SMART operations. This setting is
maintained when the power is turned off and then back on.
Once this command has been received, all SMART commands other than SMART ENABLE OPERATIONS are aborted with the
aborted Command error.
This command disables all SMART capabilities including any and all timer and event count functions related exclusively to
this feature. After command acceptance, this controller will disable all SMART operations. SMART data in no longer be
monitored or saved. The state of SMART is preserved across power cycles.
3.2.12 SMART Return Status (B0h/DAh)
Reports the drive reliability status;
Values reported when a predicted defect has not been detected:
Cylinder Low register: 4Fh
Cylinder High register: C2h
Values reported when a predicted defect has been detected:
Cylinder Low register: F4h
Cylinder High register: 2Ch
3.2.13 SMART Enable/Disable Automatic Off-line (B0h/DBh)
Enables (when Sector Count register = “F8h”) or disables (Sector Count register = “00h”) the automatic off-line data
collection function.
The automatic collection is disabled if a value of “00h” is set in the Sector Count register before a subcommand is issued. If
automatic collection is disabled, the drive can still save attribute information during normal operation, such as during the
power-on/off sequence or error correction sequence.
The automatic collection function is enabled if a value of “F8h” is set in the Sector Count register before the command is
issued. Values other than “00h” and “F8h” are vendor-specific.
