Description
Transcend industrial-grade microSD cards offer greater
design flexibility and cost savings. Despite their
compact size, the microSD cards have excellent
temperature flexibility from -40°C to 85°C. The cards
are manufactured with high-quality controller and MLC
flash chips, providing excellent shock and vibration
resistance and low power consumption that help to
bring the performance and reliability advantages of
industrial memory cards to small form factor devices.

Product Description
1.Features
1.1 Lock Function
Support for password protected locking and unlocking of SD devices. It uses the LOCK/UNLOCK
command(CMD42) which is available in SD command sets.
1.2 Built-in ECC Engine
In event of errors, the combined data allow the recovery of the original data. The number of errors that can be
recovered depends on the algorithm used.
1.3 Wear-leveling
This function means the data are no longer tied to a single physical area, which can extend Card’s life
expectancy.
1.4 Read Retry
The function allows the read voltage to be dynamically adjusted such that read errors are decreased or even
eliminated.
1.5 S.M.A.R.T. function
Transcend Industrial SD Card supports S.M.A.R.T. command (ACMD13) that allows the user to read the health
information of the SD. Transcend also define some innovated S.M.A.R.T. features which allows the user to
evaluate the status of the SD in a much more efficient way.
2. Bus Topology
The SD Memory Card system defines two alternative communication protocols:SD and SPI. The host system
can choose either one of modes. The card detects which mode is request by host when the reset command is
received and expects all further communication to be in the same communication mode.
2.1 SD Bus
For more details, refer to Section 3.5.1 of the SDA Physical Layer Specification, Version 3.01.
2.2 SPI Bus
For more details, refer to Section 3.5.2 of the SDA Physical Layer Specification, Version 3.01.
3.SD card Register information
3.1 OCR register
The OCR register stores the VDD voltage profile of the card,refer to Section 5.1 of the SDA Physical Layer
Specification, Version 3.01 for more information.
3.2 CID register
The Card Identification (CID) register is 128 bits wide. It contains the card identification information used
during the card identification phase. Every individual flash card shall have a unique identification number. The
structure of the CID register is defined in the following paragraphs:
• MID
An 8-bit binary number that identifies the card manufacturer. The MID number is controlled, defined, and
allocated to a SD Memory Card manufacturer by the SD-3C, LLC. This procedure is established to ensure
uniqueness of the CID register.
• OID
A 2-character ASCII string that identifies the card OEM and/or the card contents (when used as a distribution
media either on ROM or FLASH cards). The OID number is controlled, defined, and allocated to a SD Memory
Card manufacturer by the SD-3C, LLC. This procedure is established to ensure uniqueness of the CID register.
•PNM
The product name is a string, 5 ASCII characters long.
PNM can be customized by Transcend
• PRV
The product revision is composed of two Binary Coded Decimal (BCD) digits, four bits each, representing an
“n.m” revision number. The “n” is the most significant nibble and “m” is the least significant nibble.
As an example, the PRV binary value field for product revision “6.2” will be: 0110 0010
• PSN
The Serial Number is 32 bits of binary number.
PSN Number can be customized by Transcend
• MDT
The manufacturing date composed of two hexadecimal digits, one is 8 bit representing the year(y)
and the other is four bits representing the month(m).
The “m” field [11:8] is the month code. 1 = January.
The “y” field [19:12] is the year code. 0 = 2000.
As an example, the binary value of the Date field for production date “April 2001” will be:
00000001 0100.
MDT can be customized by Transcend
• CRC
CRC7 checksum (7 bits).
3.3 CSD register
The following sections describe the CSD fields and the relevant data types for the standard and High Capacity
SD Memory Card. CSD Version 1.0 is applied Capacity SD Memory Card and CSD Version is applied to 2.0 is
applied to only the High Capacity SD Memory Card. The field name in parenthesis is set to fixed value and
indicates that the host is not necessary to refer these fields. The fixed values enables host, which refers to
these fields, to keep compatibility to CSD Version 1.0. The Cell Type field is coded as follows: R = readable, W(1)
= writable once, W = multiple writable.

3.4 RCA register
The writable 16-bit relative card address register carries the card address that is published by the card during
the card identification. Refer to Section 5.4 in the SDA Physical Layer Specification, Version 3.01 for more
information.
3.5 SCR register
In addition to the CSD register, there is another configuration register named SD CARD configuration Register,
SCR provide information on the SD memory card’s special feature that were configured into the given
card.Refer to Section 5.6 in the SDA Physical Layer Specification, Version 3.01 for more information.
3.6 SSR register
The SD status contains status bits that are related to the SD memory card proprietary features and may be
used for future application-specific usage. The SD Status structure is described in Section 4.10.2 in the SDA
Physical Layer Specification, Version 3.01.
The above technical information is based on industry standard data and has been tested to be reliable. However, Transcend makes no
warranty, either expressed or implied, as to its accuracy and assumes no liability in connection with the use of this product. Transcend
