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. 3.3.1 CSD Register Structure CSD_STRUCTURE CSD Structure version Card capacity 0 CSD Version1.0 Standard Capacity 1 CSD Version2.0 High Capacity and Extended Capacity 2-3 reserved 3.3.2 CSD Register Structure (CSD Version 1.0) 3.3.3 CSD Register (CSD Version 2.0) 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.
