The OCR, CID, CSD and SCR registers carry the card/content specific information, while the RCA and DSR registers are configuration registers storing actual configuration parameters. 1. OCR register The 32-bit operation conditions register stores the VDD voltage profile of the card. One status bit is set if the card power up procedure has been finished. [. . . ] 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. Note: SD-3C, LLC licenses companies that wish to manufacture and/or sell SD Memory Cards, including but not limited to flash memory, ROM, OTP, RAM, and SDIO Combo Cards. SD-3C, LLC is a limited liability company established by Matsushita Electric Industrial Co. Ltd. , SanDisk Corporation and Toshiba Corporation. · PNM The product name is a string, 5 ASCII characters long. · PRV The product revision is composed of two Binary Coded Decimal (BCD) digits, four bits each, representing an "n. m" Transcend Information Inc. 12 microSDHC Card series High Capacity microSD Class10 Card 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. · 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). As an example, the binary value of the Date field for production date "April 2001" will be: 00000001 0100. · CRC CRC7 checksum (7 bits). 3. CSD Register The following sections describe the CSD fields and the relevant data types for 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. Transcend Information Inc. 13 microSDHC Card series High Capacity microSD Class10 Card The CSD Register Fields (CSD Version 2. 0) The following sections describe the CSD fields and the relevant data types. If not explicitly defined otherwise, all bit strings are interpreted as binary coded numbers starting with the left bit first. · CSD_STRUCTURE Field structures of the CSD register are different depend on the Physical Specification Version and Card Capacity. The CSD_STRUCTURE field in the CSD register indicates its structure version. If set, a driver stage register (DSR)must be implemented also. Transcend Information Inc. 16 microSDHC Card series High Capacity microSD Class10 Card · C_SIZE This field is expanded to 22 bits and can indicate up to 2 TBytes (It is the same as the maximum memory space specified by a 32-bit block address. ) This parameter is used to calculate the user data area capacity in the SD memory card (not include the protected area). The user data area capacity is calculated from C_SIZE as follows: memory capacity = (C_SIZE+1) * 512K byte As the maximum capacity of the Physical Layer Specification Version 2. 00 is 32 GB, the upper 6 bits of this field shall be set to 0. · ERASE_BLK_EN This field is fixed to 1, which means the host can erase one or multiple units of 512 bytes. · SECTOR_SIZE This field is fixed to 7Fh, which indicates 64 KBytes. Version 2. 00 cards indicates memory boundary by AU size and this field should not be used. · WP_GRP_SIZE This field is fixed to 00h. The High Capacity SD Memory Card does not support write protected groups. · WP_GRP_ENABLE This field is fixed to 0. The High Capacity SD Memory Card does not support write protected groups. · R2W_FACTOR This field is fixed to 2h, which indicates 4 multiples. Write timeout can be calculated by multiplying the read access time and R2W_FACTOR. However, the host should not use this factor and should use 250 ms for write timeout · WRITE_BL_LEN This field is fixed to 9h, which indicates WRITE_BL_LEN=512 Byte. · WRITE_BL_PARTIAL This field is fixed to 0, which indicates partial block read is inhibited and only unit of block access is allowed. · FILE_FORMAT_GRP Transcend Information Inc. 17 microSDHC Card series This field is set to 0. Host should not use this field. High Capacity microSD Class10 Card · COPY Defines if the contents is original (= `0') or has been copied (='1'). The COPY bit for OTP and MTP devices, sold to end consumers, is set to `1' which identifies the card contents as a copy.
