TS2G~16GCFX500 CFast Card Reliability Wear-Leveling algorithm The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks' erase count is higher than a threshold value plus data blocks', it will activate the static wear leveling, replacing the not so frequently used user blocks with the high erase count free blocks.
TS2G~16GCFX500 CFast Card CFastTM Interface Out of bank signaling There shall be three Out Of Band (OOB) signals used/detected by the Phy: COMRESET, COMINIT, and COMWAKE. COMINIT, COMRESET and COMWAKE OOB signaling shall be achieved by transmission of either a burst of four Gen1 ALIGNP primitives or a burst composed of four Gen1 Dwords with each Dword composed of four D24.3 characters, each burst having a duration of 160 UIOOB.
TS2G~16GCFX500 CFast Card COMRESET COMRESET always originates from the host controller, and forces a hardware reset in the device. It is indicated by transmitting bursts of data separated by an idle bus condition. The OOB COMRESET signal shall consist of no less than six data bursts, including inter-burst temporal spacing.
TS2G~16GCFX500 CFast Card Description: 1. Host/device is powered and operating normally with some form of active communication. 2. Some condition in the host causes the host to issue COMRESET 3. Host releases COMRESET. Once the condition causing the COMRESET is released, the host releases the COMRESET signal and puts the bus in a quiescent condition. 4. Device issues COMINIT – When the device detects the release of COMRESET, it responds with a COMINIT.
TS2G~16GCFX500 CFast Card COMINIT COMINIT always originates from the drive and requests a communication initialization. It is electrically identical to the COMRESET signal except that it originates from the device and is sent to the host. It is used by the device to request a reset from the host in accordance to the sequence shown in Figure 6, below. Figure 6 : cominit sequence Description: 1. Host/device are powered and operating normally with some form of active communication. 2.
TS2G~16GCFX500 CFast Card Dword times.) This step is repeated for as many slower speeds as are supported. Once the lowest speed has been reached without response from the host, the device enters an error state. 5. Host locks – after detecting the COMWAKE, the host starts transmitting D10.2 characters at its lowest supported rate. Meanwhile, the host receiver locks to the ALIGN sequence and, when ready, returns the ALIGN sequence to the device at the same speed as received.
TS2G~16GCFX500 CFast Card Description: 1. Host/device power-off - Host and device power-off. 2. Power is applied - Host side signal conditioning pulls TX and RX pairs to neutral state (common mode voltage). 3. Host issues COMRESET 4. Host releases COMRESET. Once the power-on reset is released, the host releases the COMRESET signal and puts the bus in a quiescent condition. 5. Device issues COMINIT – When the device detects the release of COMRESET, it responds with a COMINIT.
TS2G~16GCFX500 CFast Card ATA command register This table with the following paragraphs summarizes the ATA command set.
TS2G~16GCFX500 CFast Card ATA Command Specifications FLUSH CACHE (E7h) This command is used by the host to request the device to flush the write cache. If there is data in the write cache, that data shall be written to the media. The BSY bit shall remain set to one until all data has been successfully written or an error occurs. IDENTIFY DEVICE (ECh) This commands read out 512Bytes of drive parameter information. Parameter Information consists of the arrangement and value as shown in the following table.

TS2G~16GCFX500 CFast Card 66 0078h 2 Recommended Multiword DMA transfer cycle time.
TS2G~16GCFX500 CFast Card READ DMA (C8h) Read data from sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify the mode value. A sector count of zero requests 256 sectors. READ MULTIPLE (C4h) This command performs similarly to the Read Sectors command. Interrupts are not generated on each sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command.
TS2G~16GCFX500 CFast Card This command enables the host to write the contents of one 512-byte block of data to the device’s buffer. Power Management Feature Set CHECK POWER MODE (E5h or 98h) The host can use this command to determine the current power management mode. IDLE (E3h or 97h) This command causes the device to set BSY, enter the Idle mode, clear BSY and generate an interrupt. If sector count is non-zero, the automatic power down mode is enabled.

TS2G~16GCFX500 CFast Card SECURITY UNLOCK (F2h) This command disables LOCKED MODE of the device. This command transfers 512 bytes of data from the host with PIO data-out protocol. The following table defines the content of this information.
TS2G~16GCFX500 CFast Card The drive exits from Frozen mode upon a power-off or hard reset. If the SECURITY FREEZE LOCK command is issued when the drive is placed in Frozen mode, the drive executes the command, staying in Frozen mode. SMART Feature Set Transcend IDE SSD supports the SMART command set and define some vendor-specific data to report spare/bad block numbers in each memory management unit. Individual SMART commands are identified by the value placed in the Feature register.
TS2G~16GCFX500 CFast Card memory, or execute a self-diagnostic test routine in either captive or off-line mode. SMART RETURN STATUS B0h with a Feature register value of DAh. This command causes the device to communicate the reliability status of the device to the host. If a threshold exceeded condition is not detected by the device, the device shall set the LBA Mid register to 4Fh and the LBA High register to C2h.
