Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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. It contains the card identification information used during the card identification phase. Every individual flash card shall have a unique identification number.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series • 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. 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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 (See 4.6.2). • NSAC This field is fixed to 00h. NSAC should not be used to calculate time-out values.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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).
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series • 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).
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series 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.
Ver 1.1 4~32GB High Capacity microSD Card microSDHC4 Card series • SD_SECURITY Describes the security algorithm supported by the card. SD Supported Security Algorithm Note that it is mandatory for a regular writable SD Memory Card to support Security Protocol. For ROM (Read Only) and OTP (One Time Programmable) types of the SD Memory Card, the security feature is optional. In the case of Standard Capacity SD Memory Card, this field shall be set to 2 (Version 1.01).
