Cactus Technologies SD products are low capacity solid-state flash memory products that complies with the SD Association standard. Cactus SD products provide up to 8GB of formatted storage capacity and is designed to be used in applications which requires reliable, high performance solid state storage in a small form factor. Cactus Technologies Industrial Grade SDChipTM provides up to 8GB of formatted storage capacity in a small 23mm x 21mm BGA form factor.
1.1. Supported Standards Cactus Technologies SD products are fully electrically compatible with the following specification: • SD Card Association Physical Layer Specification, Versions 1.01, 1.1 and 2.0 1.2. Product Features Cactus Technologies Industrial SD products contain a high level, intelligent controller. This intelligent controller provides many capabilities including the following: • • • • • SD Card register and command set handling.
1.2.3. Intelligent Power Management Cactus Technologies Industrial SD products employ sophisticated power management algorithms to conserve power. Upon completion of a command, the drive will automatically enter sleep mode if no further commands are received. In most situations, the drive will be in sleep mode except when the host is accessing it, thus conserving power. When the drive is in sleep mode, any command issued to the drive will cause it to exit sleep and respond. 1.2.4.
NOTES: All values quoted are typical values at room temperature and nominal supply voltage unless otherwise stated. Sleep mode is specified under the condition that all drive inputs are static CMOS levels and in a “Not Busy“ operating state and with the input clock stopped. 2.3. System Performance All performance timings are typical values under normal operating conditions and assuming the drive controller is in the default (i.e., fastest) mode. Table 2-3.

2.6. Capacity Specifications Cactus Technologies -806 series SD card and SDChip products come in capacities of 128M, 256M, 512M, 1G, 2G, 4G and 8G. 3.Interface Description The following sections provide detailed information on the Cactus Technologies Industrial SD products interface. 3.1. SD Card Pin Assignments and Pin Type The signal/pin assignments are listed in Table 3-5. Signals are active high unless otherwise specified. Table 3-5.
SPI mode connections: Ball # Signal C8 CSN C7 SDI B1,C3,C6,G7 VSS B8,C5,G5 VDD C4 SCLK C2 SDO 3.3. Signal Description Table 3-6 describes the I/O signals. Signals whose source is the host are designated as inputs while signals that the SD Card sources are outputs. The SD Card logic levels conform to those specified in the SDA Physical Layer Specification, version 1.1. Table 3-6. Signal Description Signal Name CD/DAT3 (SD mode) Dir.
Signal Name DAT0 SDO DAT1 DAT2 Dir. I/O/ PP O Description This pin is input on power up. It will function as a data line once the host has issued a SET_BUS_WIDTH command. In SPI mode, this pin is serial data out from the card. I/O/ PP These pins are inputs on power up. They will function as data lines once the host hast issued a SET_BUS_WIDTH command. 3.4. Bus Protocol The Cactus Technologies SD products bus protocol is compliant to SDA Physical Layer Specifications, Version 1.01, 1.1 and 2.0.
3.5.3. 3.5.3.1. AC Characteristics Bus Timing Please refer to Sections 6.7 and 6.8 of the SDA Physical Layer Specifications, Version 1.1 for bus timing specifications for default mode and high speed mode. Cactus Technologies Limited Industrial Grade -806 SD Card & SDChipTM Product Manual v2.
4. Register Table This section describes the values in the SD registers of Cactus Technologies SD products. 4.1. Operation Condition Register (OCR) This 32-bit register stores the VDD voltage profile of the card. In addition, bit 31 is a status bit which is set to '1' if the card power up procedure has completed. When bit 31 is set, bit 30 will be valid and identifies whether the card is a Standard ('0') or High Capacity ('1') SD card. OCR bit VDD range Value [6:0] Reserved 000 0000 b [7] 1.
4.3. Relative Card Address Register (RCA) This 16-bit register stores the card address assigned by the host during the card identification phase. The default value is 0x0000. In SD mode, the value in this register is generated by a random number generator as per SDA specifications. 4.4. Card Specific Data Register (CSD) This 128-bit register provides information on how to access the card content.

Offset Description 41-40 Lowest wear level class 43-42 Highest wear level class 45-44 Wear level threshold 51-46 Total number of block erases 53-52 Number of flash blocks 55-54 Maximum flash block erase count target, in wear level class units 59-56 Power on count 63-60 Firmware version 5.1. Offset 25 Data structure version identifier This is the version of this SMART information in the -806 SD card.
5.4. Offset 31-30 Number of initial spare blocks (2nd flash CE across channel) This is the number of spare blocks reserved during the low level format. When there is runtime bad block, a spare block will be withdrawn from the spare block pool and this spare block will replace the run-time bad block; the run-time bad block will be marked as defect and will not be used again. This number is for NAND flash(s) connected to the 2nd flash CE of the controller. 5.5.
5.9. Offset 41-40 Lowest wear level class Each wear level class represents different number of block erasure for blocks inside that class. A flash block in wear level class 'N' means the flash block has been erased (N*(wear level threshold+1)) to ((N+1)*wear level threshold+N) times. The lowest wear level class 'N' means the minimum number of blocks erase (against all blocks) is class 'N'. 5.10.
