compactflash memory card product manual sandisk compactflash memory card product manual ?1999 sandisk corporation 7 1.0 introduction to the compactflash memory card the sandisk compactflasha memory card (cfa) products provide high capacity solid state flash memory that electrically complies with the personal computer memory card international association ata (pc card ata) standard. (in japan, the applicable standards group is jeida.) the compactflash memory card series also supports a true ide mode that is electrically compatible with an ide disk drive. compactflash memory cards provide up to 160 million bytes (megabytes, mbytes or mb) of formatted storage capacity in the cf type ii form factor and 96 megabytes in the original cf form factor. the original cf form factor card can be used in any system that has a cf slot, and with a type ii pcmcia adapter can be used in any system that has a pcmcia type ii or type iii socket. the newer cf type ii card fits into a cf type ii slot. sandisk has expanded the av ailable capacity of the compactflash storage card by offering a new cf type ii form factor. just slightly thicker than the original cf form factor, the cf type ii form factor is 5 mm thick instead of 3.3 mm thick. the compactflash memory card series uses sandisk flash memory chips which were designed by sandisk specifically for use in mass storage a pplications. in addition to the mass storage specific flash memory chips, the compactflash memory cards include an on-card intelligent controller that provides a high level interface to the host computer. this interface allows a host computer to issue commands to t h e memory card to read or write blocks of memory. a block of memory consists of 512 bytes of data and is protected by a powerful error correcting code (ecc). the compactflash memory card on-card intelligent controller manages interface protocols, data storage and retrieval as well as ecc, defect handling and diagnostics, power management and clock control. once the compactflash memory card has been configured by the host, it appears to the host as a standard ata (ide) disk drive. additional ata commands have been provided to enhance system performance. the host system can support as many cards as there are compactflash, compactflash type i i and pcmcia type ii or iii card slots. the original form factor compactflash memory cards require a pcmcia type ii adapter to be used in a pcmcia type ii or type iii socket. sandisk also offers an industrial version of the compactflash memory card series, which has a broader operating and non-operating temperature range than the standard product. please see section 2 for detailed specifications. sandisk single chip c ontroller host interface data in/o ut control sandisk flash modules sandisk compactflash figure 1-1 compactflash memory card block diagram

compactflash memory card product manual sandisk compactflash memory card product manual ?1999 sandisk corporation 12 1.7.5 t rue ide mode the compactflash memory card differs from t h e sdp5a flashdisk in that it can be configured in true ide mode. see section 4.6 true ide mode i/o transfer function. 1.7.6 identify drive information word 51 of the identify drive command information has a default value of 0000h for t h e sdp5a flashdisk. the data field type information for this word is pio data transfer cycle timing mode 0. for the compactflash memory card, word 51 of the identify drive command information has a default value of 0001h. the data field type information for this word is pio data transfer cycle timing mode 1. 1.8 functional description compactflash memory cards contain a high level, intelligent subsystem as shown in the block diagram, figure 1-1. this intelligent (microprocessor) subsystem provides many capabilities not found in other types of memory cards. these capabilities include: 1. standard ata register and command set (same as found on most magnetic disk drives). 2. host independence from details of erasing and programming flash memory. 3. sophisticated system for managing defects (analogous to systems found in magnetic disk drives). 4. sophisticated system for error recovery including a powerful error correction code (ecc). 5. power management for low power operation. 1.8.1 flash technology independence the 512 byte sector size of compactflash memory card is the same as t hat in an ide magnetic disk drive. to write or read a sector (or multiple sectors), the host computer software simply issues a read or write command to the compactflash memory card. this command contains the address and the number of se ctors to write/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 important as flash devices are expected to get more and more complex in the future. since the compactflash memory card series uses an intelligent on-board controller, the host system software will not require changing as new flash memory evolves. in other words, systems that support t h e compactflash memory card today will be able to access future sandisk cards built with new flash technology without having to update or change host software. 1.8.2 defect and error management compactflash memory cards contain a sophisticated defect and error management system. this system is analogous to the systems found in magnetic disk drives and in many cases offers enhancements. for instance, disk drives do not typically perform a read after write to confirm the data is written correctly because of t h e performance penalty that would be incurred. compactflash memory cards do a read after write under margin conditions to verify that the data is written correctly (except in the case of a write without erase command). in the rare case that a bit is found to be defective, compactflash memory cards replace this bad bit with a spare bit within the sector header. if necessary, compactflash memory cards will even replace the entire sector with a spare sector. this is completely transparent to the host and does not consume any user data space. the compactflash memory card soft error rate specification is much better than the magnetic disk drive specification. in the extremely rare case a read error does occur, compactflash memory cards have innovative algorithms to
compactflash memory card product manual sandisk compactflash memory card product manual ?1999 sandisk corporation 13 recover the data. this is similar to using retries on a disk drive but is much more sophisticated. the last line of defense is to employ a powerful ecc to correct the da ta. if ecc is used to recover data, defective bits are replaced with spare bits to ensure they do not cause any future problems. these defect and error management systems coupled with the solid state construction give compactflash memory cards unparalleled reliability. 1.8.3 endurance compactflash memory cards have an endurance specification for each sector of 300,000 writes (reading a logical sector is unlimited). this is far beyond what is needed in nearly all applications of compactflash memory cards. even very heavy use of compactflash card in digital cameras, cellular phones, pdas, personal communicators, pagers, voice recorders, ruggedized handheld computers, palmtop and notebook computers will use only a fraction of the total endurance over t h e typical computer?s five year lifetime. for instance, it would take over 34 years to wear out an area on the compactflash card on which a file of any size (from 512 bytes to capacity) was rewritten 3 times per hour, 8 hours a day, 365 days per year. with typical applications (pim software, word processing, spreadsheets, etc.), the endurance limit is not of any practical concern to the vast majority of users. 1.8.4 wear leveling compactflash memory card series products do not require or perform a wear level operation. the command is supported as a nop operation to maintain backward compatibility with existing software utilities. 1.8.5 using the erase sector and write without erase commands the erase sector and write without erase commands provide the capability to substantially increase the write performance of t h e compactflash memory card. once a sector h a s been erased using the erase sector command, a write to that sector will be much faster. this is because a normal write operation includes a separate sector erase prior to write. an example of where these commands may be useful is in a digital camera. the camera user may have plenty of time to erase pictures but may wish to take several pictures in rapid succession. to accomplish this, the host system (i.e., camera) would use the erase sectors command to pre-erase the sectors that will store the pictures. when the pictures are taken, the camera can store them in the previously erased sectors much faster than in non-erased sectors. 1.8.5.1 interaction with systems not aware of the erase sector and write without erase commands many systems that can read and write compactflash memory cards may not be aware of the erase sector and write without erase commands. these systems would not issue these commands but such a system might attempt a normal write or a normal read to a pre-erased sector. a normal write to a pre-erased sector will function correctly, but will be at the normal write speed that is slower than a write without erase command. if a normal read is attempted to a pre-erased sector, compactflash memory cards will detect it is pre-erased and will return zero data and will not re port an error even though the data ecc i s not valid. if an un-aware host system over-writes a pre- erased sector with a normal write and then t h e compactflash memory card is moved to t h e system that created the erased sectors, a situation exists where a write without erase might be
compactflash memory card product manual sandisk compactflash memory card product manual ?1999 sandisk corporation 14 attempted to a normal sector. if this occurs, the compactflash card will perform a normal write which means it will first erase the sector and then do a full write with all mar gin modes enabled. this write will of course be slower than if the sector were in fact pre-erased. 1.8.5.2 limitations and issues the advantage of the write without erase and erase sector commands is that they shift the bulk of the erase and write time to the erase sector command. the erase sector command performs most of the normal tasks needed. to increase t h e speed of the write without erase command, t h e final margin verify done in a normal write command is skipped for the first 16k wri tes. when the cycle count (hot count) of a sector exceeds 16k, the system controller automatically reverts to a full write, including the final margin verify. since the erase is not required in this case, a write to a pre-erased sector with a hot count of over 16k is still faster than to a sector that h a s not been pre-erased. the translate sector command can be used to determine the hot count of a sector. 1.8.6 automatic sleep mode a unique feature of the sandisk compactflash memory card (and other sandisk products) i s automatic entrance and exit from sleep mode. upon completion of a command, t h e compactflash card will enter the sleep mode to conserve power if no further commands a r e received within 5 msec. the host does not have to take any action for this to occur. in most systems, the compactflash memory card is in sleep mode except when the host is accessing it, thus conserving power. note that the delay from command completion to entering sleep mode can be adjusted. when the host is ready to access t h e compactflash memory card and it is in sleep mode, any command issued to the compactflash card will cause it to exit sleep and respond. the host does not have to follow the ata protocol of issuing a reset first. it may do this if desired, but it is not needed. by not issuing the reset, performance is improved through the reduction of overhead but this must be done only for t h e sandisk products as other ata products may not support this feature. 1.8.7 dynamic adjustment of performance versus power consumption a very unique and valuable feature of the compactflash memory card is the ability of the host to control the power the card consumes. this allows compactflash cards to work across a broad cross section of platforms without compromising performance. for instance, it can operate in a platform that provides only 32 ma a t 3.3 volts average current (of course at reduced performance) or in a platform that provides 90 ma at full performance. please see the set features command for details. 1.8.8 power supply requirements this is a dual voltage product which means i t will operate at a voltage range of 3.30 volts 5% or 5.00 volts 10% ( 5% for industrial versions). per the pcmcia specification section 2.1.1, t h e host system must apply 0 volts in order to change a voltage range. this same proce dure of providing 0 volts to the card is required if the host system applies an input voltage outside the desired voltage by more than 20%. this means less than 4.0 volts for the 5.00 volt range and less than 2.70 volts for the 3.30 volt range.

compactflash memory card product manual sandisk compactflash memory card product manual ?1999 sandisk corporation 79 when the write multiple command is issued, t h e sector count register contains the number of sectors (not the number of blocks or the block count) requested. if the number of requested sectors is not evenly divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial block transfer. the partial block transfer is for n sectors, where: n = remainder (sector count/block count). if the write multiple command is attempted before the set multiple mode command has been executed or when write multiple commands a r e disabled, the write multiple operation will be rejected with an aborted command error. errors encountered during write multiple commands are posted after the attem pted writes of the block or partial block transferred. the write command ends with the sector in error, even if it is in the middle of a block. subsequent blocks are not transferred in the event of an error. interrupts are generated when drq is set at t h e beginning of each block or partial block. the command block registers contain t h e cylinder, head and sector number of the sector where the error occurred and the sector count register contains the residual num ber of sectors that need to be transferred for successful completion of the command e.g. each block has 4 sectors, a request for 8 sectors is issued and an error occurs on the third sector. the sector count register contains 6 and the address is that of t h e third sector. 6.1.27 write multiple without erase - cdh bit -> 7 6 54321 0 command (7) cdh c/d/h (6) x lba x drive head cyl high (5) cylinder high cyl low (4) cylinder low sec num (3) sector number sec cnt (2) sector count feature (1) x this command is similar to the write multiple command with the exception that an implied erase before write operation is not performed. the sectors should be pre-erased with the erase sector(s) command before this command is issued. refer to section 1.8.5 using the erase sector and write without erase commands and to section 6.1.29 write sector(s) without erase - 38h for an expanded definition of the write sector(s) without erase command.
