Industrial UDMA 6 CompactFlash L500539 Rev. B The Industrial UDMA 6 CompactFlash cards are manufactured in the USA at our own facilities in Poway, California. The cards are supported by Delkin’s locked-down Bill of Materials that ensures consistent product performance and future compatibility. Delkin’s Industrial line of CompactFlash is the perfect solution for enterprises demanding specific higher qualitative and performance functions in a widely accepted, time-tested form factor. ## **Applications:** - Industrial Computers - Embedded Systems - Data Acquisition - Automotive - Flight Systems ● Agriculture - Manufacturing ● Gaming - Military - Telecommunications ## **Optional Conformal Coating** Delkin’s proprietary conformal coating defends data integrity in harsh environments. Delkin utilizes a low-viscosity silicon elastomer that thoroughly covers exposed board and component surfaces with a protective coating. This process shields memory electronics from moisture and contamination, preventing metal corrosion and insulating conductors against electrical leakage. The coating also ruggedizes devices against the vibration, shock, and thermal stress of severe-service applications. Conformal coating is available as an option for Delkin industrial flash memory products in many form factors, including solid state drives, CompactFlash, Secure Digital, removable and embedded USB, PCMCIA, and mSATA. 5 ©2014 Delkin Devices, Inc.

The two timing sequences are explained in detail in the PCMICA PC Card Standard. Delkin’s CompactFlash Card conforms to the timing in that reference document. ## **4.8 CF-ATA Command Description** This section defines the software requirements and the format of the commands the host sends to the CompactFlash cards. Commands are issued to the CompactFlash card by loading the required registers in the command block with the supplied parameters, and then writing the command code to the Command register. The manner in which a command is accepted varies. These are three classes of command acceptance, all dependent on the host not issuing commands unless the CompactFlash card is not busy (BSY=0). ## **4.8.1 CF-ATA Command set** The following table summarizes the CF-ATA command set with the paragraphs that follow describing the individual commands and the tasks file for each.

If in PCMCIA configuration this command runs only on the CompactFlash card which is addressed by the Drive/Head register when the diagnostic command is issued. This is because PCMCIA card interface does not allow for direct inter-drive communication (such as the ATA PDIAG and DASP signals). If in True IDE mode the Drive bit is ignored and the diagnostic command is executed by both the master and the slave with the master responding with status for both devices. The Diagnostic codes shown below are returned in the Error register at the end of the command. ## **Diagnostic Codes** |Code|Error Type| |---|---| |01H|No Error Detected| |02H|Formatter Device Error| |03H|Sector Buffer Error| |04H|ECC Circuitry Error| |05H|Controlling Microprocessor Error| |8XH|Slave Error in True IDE mode| 20 ©2014 Delkin Devices, Inc.

To remain host backward compatible, the CompactFlash card expects a sector buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command although the information in the buffer is not used by the CompactFlash card. If LBA=1 then the number of sectors to format is taken from Sec Cnt register (0=256). The use of this command is not recommended. ## **4.8.7 Identify Drive - ECH** |**Bit –>**|**7**|**6**|**5**|**4**|**3**|**2**|**1**|**0**| |---|---|---|---|---|---|---|---|---| |**Command (7)**|ECH|||||||| |**C/D/H (6)**|X|X|X|Drive|X|||| |**Cyl High (5)**|X|||||||| |**Cyl Low (4)**|X|||||||| |**Sec Num (3)**|X|||||||| |**Sec Cnt (2)**|X|||||||| |**Feature (1)**|X|||||||| The Identify Drive command enables the host to receive parameter information from the CompactFlash card.

If a threshold exceeded condition exists for either the Spare Block Count attribute or the Erase Count attribute, the device will set the Cylinder Low register to F4h and the Cylinder High register to 2Ch. If no threshold exceeded condition exists, the device will set the Cylinder Low register to F4h and the Cylinder High register to C2h. ## **6.4 SMART Read Log** COMMAND CODE – B0h with a Feature Register value of D5h PROTOCOL – PIO data in.

ERROR OUTPUTS – Aborted if either the signature in the Cylinder registers is invalid, if the Sector Count is not 1, or if SMART is not enabled. DESCRIPTION – This command returns one sector of spare block information. The information is the initial number of blocks (directly after the preformat) per flash chip available for bad block remap, and the current number of blocks per flash chip available for bad block remap. The layout of the returned sector is: |Offset|Description| |---|---| |0 - 31|Initial number of replacement blocks for chips 0 – 15,2 bytesper entry| |32 – 63|Current number of replacement blocks for chips 0 – 15,2 bytesper entry| |64 - 511|----| ## **6.7 SMART Read Wear Level Data** COMMAND CODE – B0h with a Feature Register value of E1h PROTOCOL – PIO data in.

Industrial UDMA 6 CompactFlash L500539 Rev. B ERROR OUTPUTS – Aborted if either the signature in the Cylinder registers is invalid, if the Sector Count is not 4, or if SMART is not enabled. DESCRIPTION – This command will return four sectors of information regarding the status of the wear leveling. The information returned is the distribution of the blocks into the 1024 possible wear level classes. The layout of the returned sector is: |leveling. The<br>classes. The|information returned is the distribution of the blocks into the 1024 poss<br>layout of the returned sector is:| |---|---| |Offset|Description| |0 - 3|Marker Bytes,fixed value 0xFFFFFFFF| |4 – 5|Lowest Wear Level Class| |6 – 7|Highest Wear Level Class| |8 – 15|Wear Level Class entry1| |16 – 23|Wear Level Class entry2| |24 – 31|Wear Level Class entry3| |….|….| |2040 - 2047|Wear Level Class entry255| Each Wear Level Class entry consists of this data: |Offset|Description| |---|---| |0 - 3|Wear Level Class Index| |4 – 7|Number of blocks in this Wear Level Class| Unused Wear Level Class entries are zero. A block moves from one wear level class into the next when it reaches the number of erases that is specified as the “Wear Level Threshold” in the preformat. A common threshold number is 4095, this means that blocks in wear level class 0 have seen 0 to 4095 erases, blocks in wear level class 1 have seen 4096 to 8191 erases, and so on. Using this information, statements about the wear of the card and of the estimated remaining life can be made. 39 ©2014 Delkin Devices, Inc.
