? 2007 sandisk corporation 1-3 rev. 2.2, 06/07 sandisk sd card product fami ly product manual introduction functional description the family of sandisk sd cards contains a hi gh-level, intelligent subsystem as shown in figure 1-1. this intelligent (microprocessor) subsystem provides many capabilities not found in other types of memory cards. these capabilities include: ? host independence from details of erasing and programming flash memory ? sophisticated system for managing defects (analogous to systems found in magnetic disk drives) ? sophisticated system for error recovery including a powerful ecc ? power management for low power operation technology independence the 512-byte sector size of a card in the sandisk sd card product family is the same as that in an ide magnetic disk drive. to write or read a sector (or multiple sectors), the host software simply issues a read or write command to th e card. the command cont ains the address and number of sectors to write or read. the host software then waits for the command to complete. the host software does not get involved in the details of how the flash memory is erased, programmed or read. this is extremely importan t because flash devices are expected to get increasingly complex in the future. because cards in the sandisk sd card product family use an intelligent on-board controller, host system software will not need to be updated as new flash memory evolves. in other words, systems that support the sd card product family today will be able to access future sandisk cards buil t with new flash technology without having to update or change host software. defect and error management the sandisk sd card product family contains a sophisticated defect and error management system. this system is analogous to the system s found in magnetic disk drives and in many cases offers enhancements. if necessary, sandisk sd card product family will rewrite data from a defective sector to a good sector. this is completely transparent to the host and does not consume any user data space. the sandisk sd card product family soft error rate specification is much better than the magnetic disk drive specification. in the extremely rare case that a read error does occur, sandisk sd card product family has innovative algorithms to recover the data. these defect and error mana gement systems, coupled with the solid state construction, give sandisk sd card product family unparalleled reliability. content protection a detailed description of the content protection mechanism and related security sd commands can be found in the sd security specification from the sda. all sd security-related commands in the sandisk sd card product fa mily operate in the data transfer mode. an authentication proced ure is done between a card and the connected device, either the lcm (pc for example) or the pd (portable device, such as sd player). after the authentication process passes, the card is ready to accept or give data from/to the connected device. while the card is in the secured mode of operation (aft er the authentication su cceeded) the argument and the associated data that is sent to the card or read from the card are encrypted. at the end of read, write or erase operations, a card auto matically gets out of its secured mode.
introduction sandisk sd card product family product manual 06/07, rev. 2.2 1-4 ? 2007 sandisk corporation wear leveling wear leveling is an intrinsic part of the erase pooling functionality of cards in the sandisk sd card product family using nand memory. automatic sleep mode a unique feature of cards in the sandisk sd card product family is automatic entrance and exit from sleep mode. upon completion of an operation, cards enter sleep mode to conserve power if no further commands are received in less than 5 milliseconds (ms). the host does not have to take any action for this to occur. however, in order to achieve the lowest sleep current, the host needs to shut down its clock to the car d. in most systems, cards are in sleep mode except when accessed by the hos t, thus conserving power. when the host is ready to access a card in slee p mode, any command issued to it will cause it to exit sleep, and respond. hot insertion support for hot insertion will be required on the host but will be supported through the connector. connector manufacturers will provide connectors that have power pins long enough to be powered before contact is made with the other pins. this approach is similar to that used in pcmcia and mmca devices to allow for hot insertion. sd card products in sd bus mode the following sections provide valuable information on cards in the sandisk sd card product family in sd bus mode. cards in the sandisk sd card product family are fully compliant with the sda physical layer specification, version 2.00. card specific data (csd) register structures are compliant with csd structure 1.0 and 2.0. this section covers negotiating operating conditions, card acquisition and identification, card status, memory array partitioning, read/write operations, data transfer rate, data protection in flash cards, write protection, copy bit, and csd register. additional practical card detection methods can be found in application notes pertaining to the sda physical layer specification, version 2.00.

introduction sandisk sd card product family product manual 06/07, rev. 2.2 1-6 ? 2007 sandisk corporation table 1-1 contains desc riptions for each mode. spi mode the spi mode is a secondary communication protocol for cards in the sandisk sd card product family. this mode is a subset of the sd protocol, designed to communicate with an spi channel, commonly found in motorola and other vendors' microcontrollers. detailed information about spi mode can be found in section 7 or the sda physical layer specification, version 2.00. table 1-1 mode definitions mode description single block in this mode the host reads or writ es one data block in a pre-specified length. the data block transmission is protected with 16-bit crc that is generated by the sending unit and checked by the receiving unit. the block length for read operations is li mited by the device sector size (512 bytes) but can be as small as a single byte. misalignment is not allowed. every data block must be contained in a single physical sector. the block length for write operations must be identical to the sector size and the start address aligned to a sector boundary. multiple block this mode is similar to the single block mode, except for the host can read/ write multiple data blocks (all have the same length) that are stored or retrieved from contiguous memory addresses starting at the address specified in the command. the operation is terminated with a stop transmission command. misalignment and block length restrictions apply to multiple blocks and are identical to the single block read/write operations.

interface description sandisk sd card product family product manual 07/07, rev. 2.1 3-4 ? 2007 sandisk corporation electrical interface the power scheme of sandisk sd products is handled locally in each card and in the bus master. refer to section 6.4 of the sda physical layer specification, version 2.00. power up power must be applied to the v dd pin before any i/o pin is set to logic high. in other words, cmd, clk, and dat0-3 must be at zero (0) volts when power is applied to the v dd pin. for more information, refer to section 6.4.1 of the sda physical layer specification, version 2.00. figure 3-1 recommended power control scheme the recommended power control scheme for sandisk sd, minisd, and microsd cards is illustrated in figure 3-1. most card connectors have a card detect switch that signals the sd host when the card is inserted. after the host is aware of the card insertion, it turns on the fet switch to apply power to card's v dd pin. once the card is inserted and all card pins are making contact, there is a delay before the fet switch is turned on. important because there are clamping diodes on the cmd, clk, and dat0-3 pins, it is crucial to ensure that clk, cmd, and dat0-3 are at zero (0) volts during the delay, and before fet switch is turned on. if any i/o pin, (cmd, clk, or dat0-3) goes above zero volts during the delay and before power reaches the card v dd pin, it will forward bias the clamping diodes and can cause the card to go into an unknown state. it is the host's responsibility to make sure power gets to v dd before cmd, clk, or dat0-3 go above zero volts. bus operating conditions spi mode bus operating conditions are identical to sd card bus mode operating conditions. for details, see section 6.6 of the sda physical layer specification, version 2.00. cc (5uf max) ch host vdd host vss sd host sd card fet switch on/off rpu dclamp cmd,dat0-dat3 crad vdd card vdd
