[. . . ] 1. 0 SDHC10 Card series Single card capacitance Maximum signal line inductance Pull-up resistance inside card (pin1) RDAT3 10 CCARD 4~32GB High Capacity Secure Digital Card 10 16 90 pF nH k fPP 20 MHz May be used for card detection Note that the total capacitance of CMD and DAT lines will be consist of CHOST, CBUS and one CCARD only because they are connected separately to the SD Memory Card host. Host should consider total bus capacitance for each signal as the sum of CHOST, CBUS, and CCARD, these parameters are defined by per signal. The host can determine CHOST and CBUS so that total bus capacitance is less than the card estimated capacitance load (CL=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than maximum value of CL (40 pF). Transcend Information Inc. 4 Rev. [. . . ] 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" 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 0010b · 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). Transcend Information Inc. 13 Rev. CSD Register 4~32GB High Capacity Secure Digital Card The CSD Register shows Definition of the CSD for the High Capacity SD Memory Card and Extended Capacity SD Memory Card (CSD Version 2. 0). 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 CSD_STRUCTURE field in the CSD register indicates its structure version. The following table shows the version number of the related CSD structure. CSD_STRUCTURE 0 1 2-3 CSD structure version CSD Version 1. 0 CSD Version 2. 0 reserved Card Capacity Standard Capacity High Capacity and Extended Capacity CSD Register Structure Transcend Information Inc. 15 Rev. 1. 0 SDHC10 Card series · TAAC 4~32GB High Capacity Secure Digital Card 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. TAAC bit position code 2:0 time unit 0=1ns, 1=10ns, 2=100ns, 3=1µs, 4=10µs, 5=100µs, 6=1ms, 7=10ms time value 0=reserved, 1=1. 0, 2=1. 2, 3=1. 3, 4=1. 5, 5=2. 0, 6=2. 5, 7=3. 0, 8=3. 5, 9=4. 0, A=4. 5, B=5. 0, C=5. 5, D=6. 0, E=7. 0, F=8. 0 reserved 6:3 7 · NSAC This field is fixed to 00h. NSAC should not be used to calculate time-out values. · TRAN_SPEED The following table defines the maximum data transfer rate per one data line - TRAN_SPEED: TRAN_SPEED bit 2:0 code transfer rate unit 0=100kbit/s, 1=1Mbit/s, 2=10Mbit/s, 3=100Mbit/s, 4. . . 7=reserved time value 0=reserved, 1=1. 0, 2=1. 2, 3=1. 3, 4=1. 5, 5=2. 0, 6=2. 5, 7=3. 0, 8=3. 5, 9=4. 0, A=4. 5, B=5. 0, C=5. 5, D=6. 0, E=7. 0, F=8. 0 reserved 6:3 7 Maximum Data Transfer Rate Definition Transcend Information Inc. 16 Rev. 1. 0 SDHC10 Card series 4~32GB High Capacity Secure Digital 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). The card command class register CCC defines which command classes are supported by this card. A value of `1' in a CCC bit means that the corresponding command class is supported. 11 class 11 Supported card command class class 0 class 1 Supported Card Command Classes · READ_BL_LEN This field is fixed to 9h, which indicates READ_BL_LEN=512 Byte. · READ_BL_PARTIAL This field is fixed to 0, which indicates partial block read is inhibited and only unit of block access is allowed. · WRITE_BLK_MISALIGN This field is fixed to 0, which indicates that write access crossing physical block boundaries is always disabled in SDHC and SDXC Cards. · READ_BLK_MISALIGN This field is fixed to 0, which indicates that read access crossing physical block boundaries is always disabled in SDHC and SDXC Cards. · DSR_IMP Defines if the configurable driver stage is integrated on the card.
