microSDHC Card series High Capacity microSD Class10 Card Register Information Within the card interface six registers are defined: OCR, CID, CSD, RCA, DSR and SCR. These can be accessed only by corresponding commands. 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.
microSDHC Card series High Capacity microSD Class10 Card 1) This bit is valid only when the card power up status bit is set. 2) This bit is set to LOW if the card has not finished the power up routine. A voltage range is not supported if the corresponding bit value is set to LOW. As long as the card is busy, the corresponding bit (31) is set to LOW. 2. CID Register The Card IDentification (CID) register is 128 bits wide.
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). The “m” field [11:8] is the month code. 1 = January.
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.
microSDHC Card series High Capacity microSD Class10 Card CSD_STRUCTURE CSD structure version Card Capacity 0 CSD Version 1.0 Standard Capacity 1 CSD Version 2.0 High Capacity and Extended Capacity 2-3 reserved CSD Register Structure • TAAC This field is fixed to 0Eh, which indicates 1 ms. The host should not use TAAC, NSAC, and R2W_FACTOR to calculate timeout and should uses fixed timeout values for read and write operations. • NSAC This field is fixed to 00h.
microSDHC Card series High Capacity microSD Class10 Card Note that for current SD Memory Cards that field must be always 0_0110_010b (032h) which is equal to 25MHz - the mandatory maximum operating frequency of SD Memory Card. In High-Speed mode, that field must be always 0_1011_010b (05Ah) which is equal to 50MHz. And when the timing mode returns to the default by CMD6 or CMD0 command, its value will be 032h. • CCC The SD Memory Card command set is divided into subsets (command classes).
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).
microSDHC Card series High Capacity microSD Class10 Card This field is set to 0. Host should not use this field. • 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. The COPY bit is an one time programmable bit.
microSDHC Card series High Capacity microSD Class10 Card 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. This address is used for the addressed host-card communication after the card identification procedure. The default value of the RCA register is 0x0000. The value0x0000 is reserved to set all cards into the Stand-by State with CMD7. 5.
microSDHC Card series High Capacity microSD Class10 Card 6. SCR Register In addition to the CSD register there is another configuration register that named - SD CARD Configuration Register (SCR). SCR provides information on SD Memory Card's special features that were configured into the given card. The size of SCR register is 64 bit. This register shall be set in the factory by the SD Memory Card manufacturer. The following table describes the SCR register content.
microSDHC Card series High Capacity microSD Class10 Card • SD_SPEC Describes the SD Memory Card Physical Layer Specification version supported by this card. SD_SPEC 0 1 Physical Layer Specification Version Number Version 1.0-1.01 Version 1.10 Version 2.00 or Version 3.00 (Refer to SD_SPEC3) reserved Physical Layer Specification Version 2 3-15 • SD_SPEC3 SD_SPEC SD_SPEC3 Physical Layer Specification Version Number 2 0 Version 2.00 2 1 Version 3.
microSDHC Card series High Capacity microSD Class10 Card (5) Speed Class shall be supported (SDHC or SDXC) A card supports any of following functions shall satisfy essential conditions of Version 3.00 Card (1) Speed Class supported under the conditions defined in Ver3.00 (2) UHS-I supported card (3) CMD23 supported card Application Notes: When checking SD_SPEC version in SCR, the host shall not forget that higher SD_SPEC version may be specified in future.
microSDHC Card series High Capacity microSD Class10 Card • SD_BUS_WIDTHS Describes all the DAT bus widths that are supported by this card. SD_BUS_WIDTHS Supported Bus Widths Bit 0 1 bit (DAT0) Bit 1 reserved Bit 2 4 bit (DAT0-3) Bit 3 reserved SD Memory Card Supported Bus Widths Since SD Memory Card shall support at least the two bus modes 1bit or 4bit width then any SD Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101").
