1.0 Introduction

FlashDrive Product Manual

Designed to replace traditional rotating disk drives, SanDisk FlashDrives are embedded solidstate data storage systems for mobile computing and the industrial work place. The 1.8-inch FlashDrives (model SDIB) are compatible with

1.8-inch form factor hard disk drives. The 2.5- and

3.5-inch FlashDrives (models SD25B and SD35B) are compatible with 2.5- and 3.5-inch form factor disk drives. These FlashDrives, and all SanDisk FlashDrives, feature an extremely light weight, low profile form factor with 4 to 440 megabytes (MB) of storage capacity.

SanDisk FlashDrives fit into standard disk drive bays, use the industry standard IDE interface and connect to the host system via the same ribbon cable used to connect standard disk drives. No additional device drives are required.

FlashDrives consist of an IDE compatible flash memory controller and flash memory chip(s). See Figure 1-1 for a system block diagram of these IDE FlashDrive products.

1.5.1 Flash Technology Independence

The sector size of the FlashDrives is the same as in a magnetic disk drive: 512 bytes. To write or read a sector (or multiple sectors), the host computer software simply issues a write or read command. The command contains the number of sectors to write/read and the address 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. The intelligent IDE compatible interface used by the FlashDrives will not need to change to support new flash devices in the future and therefore the host software will not need to change. Systems that support the FlashDrives today will be able to access future SanDisk IDE compatible products built with new flash technology without having to update or change host software.

1.5 Functional Description

The SanDisk FlashDrives contain a high level, intelligent subsystem as shown in the block diagram, Figure 1-1. This intelligent (microprocessor) subsystem provides many capabilities. 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).

1.5.2 Defect and Error Management

The FlashDrives contain a sophisticated defect and error management system. This system is analogous to the systems found in all magnetic disk drives and in many cases offers enhancement. For instance, disk drives do not typically perform a read after write to confirm the data is written correctly because of the performance penalty that would be incurred. The FlashDrives 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 the FlashDrives can replace this bad bit with a spare bit. If necessary the FlashDrives can 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 FlashDrive specification for soft error rate is much better than the magnetic disk drive specification. In the extremely rare case that a read error does occur, the FlashDrives have innovative algorithms to recover the data. This is similar to using retries on a disk drive but much more sophisticated. The last line of defense is to employ a powerful ECC to correct the data. If ECC

Page 10

FlashDrive Product Manual

is used to recover data, defective bits are replaced with spare bits to ensure they do not cause future problems.

These defect and error management systems coupled with the solid-state construction give the FlashDrives unparalleled reliability.

1.5.3 Endurance

Even very heavy use of the FlashDrive in a computer system will use only a fraction of the total endurance over the computer’s five year lifetime. For instance, it would take over 34 years to wear out an area on the drive on which a file of any size (from 512 bytes to drive capacity) was rewritten 3 times per hour, 8 hours a day, 365 days per year.

With typical applications (PIM software, word processing, spreadsheets, data collection, etc.), the 300,000 endurance limit is not of any practical concern to the vast majority of users.

1.5.5 Automatic Sleep Mode

A unique feature of the SanDisk FlashDrives is automatic entrance and exit from sleep mode. Upon completion of a command, the FlashDrives will enter the sleep mode to conserve power if no further commands are received within 5 msec. The host does not have to take any action for this to occur. In most systems the FlashDrives are 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 the drive and it is in sleep mode, any command issued to the drive 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 the SanDisk products as other IDE products may not have this feature.

1.5.4 Wear Leveling

The FlashDrives 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.

1.5.6 Power Supply Requirements

This is a dual voltage product which means it will operate at a voltage range of 3.30 volts ± 5% or 5.00 volts ± 10% (± 5% for industrial versions).

3.0 Installation and Mounting

3.1 Preparing to Install the FlashDrive

Follow the procedure below to prepare for the FlashDrive installation:

1. If replacing an existing hard disk drive, make sure that all data on that drive has been properly backed up.

2. Turn off the power to the host computer system and unplug the power supply cord. The host system’s power must be off during the entire installation procedure.

3. Using a grounding strap, make sure that you are properly grounded. You must be grounded during the entire installation procedure and when handling the FlashDrive.

4. Remove the host computer system’s cover.

Caution: Be sure to check with the host system’s user’s manual and the terms and conditions of the system’s warranty before removing the cover. Removing the cover of a laptop computer may be difficult and could void the system’s warranty.

5. If replacing the computer system’s existing hard drive, remove the hard drive.

If the FlashDrive is being installed as a single drive, go to section 3.3 to finish the installation process. If the FlashDrive is being installed in a two drive configuration, follow the steps in section

3.2 below to set the jumpers and then go to section

3.3 to finish the installation.

3.2.1 Jumper Settings for 1.8- and 2.5-inch FlashDrives

If the FlashDrive is being installed as the second, or Slave drive, in a two drive configuration, pin B or pin C must be grounded (see the Figures 3-1 and 3-2). Pins B and C are pulled-up input pins that are shorted together internally (Pins A and D are ground.) These pins are used to configure the FlashDrive as a slave device. When either pin B or pin C is grounded by the user, either using a shunt jumper or through a ground on the host motherboard if a 50 pin connector is used, the FlashDrive is configured as a Slave device.

If both pins B and C remain open, the FlashDrive is configured as a master in a master/slave configuration or as the only drive in a single drive system.

3.2.2 Jumper Settings for 3.5-inch FlashDrives

The jumper settings for the 3.5-inch FlashDrive are shown on the FlashDrive’s label. The master/slave configuration pins are the eight pins between the four pin power connector and the 40 pin interface connector. The figure below shows how the jumpers should be set for either master or slave configuration on the 3.5-inch FlashDrive.

Figure 3-3

3.5-inch FlashDrive Configuration Pins

3.3 Mounting the FlashDrive

Follow to the steps below to mount the FlashDrive in your computer system:

four pin power connector must also be connected on the 3.5-inch FlashDrive.

2. Mount the FlashDrive into the host system. The FlashDrive can be mounted in any orientation from the top, bottom or side. The 1.8-inch FlashDrives use four M1.6 screws in the corner mounting holes in the PC board. The 2.5-inch FlashDrive uses four M3 screws and the 3.5-inch FlashDrive uses four 6-32 screws. See Figures 2-1 through 2-5 and see the Ordering Information section at the end of this manual. Ensure that the cables are not crimped or strained. Make sure that all mounting screws are hand tightened securely. For the 3.5-inch FlashDrive, mounting screws must not extend more than .25 inch into the frame. For the 2.5-inch FlashDrive, mounting screws must not extend more than 3 mm into the frame.

3. Perform the CMOS Setup. If the computer’s BIOS has an auto-detect function, use this option, otherwise, determine if your system has a user definable “hard drive types” selection in the CMOS RAM. If your system has this selection, continue with the CMOS setup. If your system does not have this selection, call SanDisk Applications Engineering at (408) 542-0400.

Refer to the following table for information required to set the user definable “hard disk type” selection in your system’s CMOS RAM to the FlashDrive configuration. The table lists the number of heads, sectors per track and cylinders emulated by the FlashDrives. After entering the appropriate information, save the new CMOS setup by rebooting your system.

1. Connect the FlashDrive to the host system. If the host system’s cable connector is not keyed, make sure that pin 1 from the host computer cable is connected to pin 1 of the FlashDrive. Pin 1 on both connectors has a square solder pad. If the FlashDrive is being added to the system as a slave drive, connect the daisychained connector to the FlashDrive. The

SLAVE Mode Pins B and C are pulled-up input pins that are shorted together internally. (Pins A and D are ground.) These pins are used to configure the FlashDrive as a Slave device. When either pin B or pin C is grounded by the user, either using a shunt jumper or through a ground on the host motherboard if a 50 pin connector is used, the FlashDrive is configured as a Slave device. If both pins B and C remain open, the FlashDrive is configured as a Master in a Master/Slave configuration or as the only drive in a single drive system.

Reset signal from the host that is active on power up and inactive thereafter.

HOST DATA (15-0) These 16 lines carry the Data between the controller and the host. The low 8 lines transfer commands, status and ECC information between the host and the controller.

This strobe pulse is used to clock data or commands on the host data bus into the controller. The clocking will occur on the negative to positive edge of the signal (trailing edge).

This is a read strobe generated by the host. This signal gates data or status on the host bus and strobes the data from the controller into the host on the low to high transition (trailing edge).

This is an interrupt request from the controller to the host, asking for service. The output of this signal is tri-stated when the interrupts are disabled by the host.

This open drain output is asserted low by the controller to indicate to the host the current cycle is a 16 bit word data transfer.

This bi-directional open drain signal is asserted by the slave after an Execute Diagnostic command to indicate to the master it has passed it’s diagnostics.

These address lines are used to select the registers within the controller task file.

Commands are issued to the FlashDrive by loading the required registers in the command block with the supplied parameters, and then writing the command code to the Command Register. The manner in which a command is accepted varies. There are three classes (see Table 6-1) of command acceptance, all dependent on the host not issuing commands unless the FlashDrive is not busy . (The BUSY bit in the status and alternate status registers is 0.)

• Upon receipt of a Class 1 command, the

FlashDrive sets the BUSY bit within 400 nsec.

• Upon receipt of a Class 2 command, the

FlashDrive sets the BUSY bit within 400 nsec, sets up the sector buffer for a write operation, sets DRQ within 700 µsec, and clears the BUSY bit within 400 nsec of setting DRQ.

• Upon receipt of a Class 3 command, the FlashDrive sets the BUSY bit within 400 nsec, sets up the sector buffer for a write operation, sets DRQ within 20 msec (assuming no re-assignments), and clears the BUSY bit within 400 nsec of setting DRQ.

Note: The current revision of the FlashDrive only supports a block count of 1 as indicated in the Identify Drive

Information command. This command is provided for compatibility with future products which may support a larger block count.

The Read Multiple command performs similarly to the Read Sectors command. Interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command.

Command execution is identical to the Read Sectors operation except that the number of sectors defined by a Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector.

The block count of sectors to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Read Multiple command. When the Read Multiple command is issued, the 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 block count, 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 Read Multiple command is attempted before the Set Multiple Mode command has been executed or when Read Multiple commands are

disabled, the Read Multiple operation is rejected with an Aborted Command error. Disk errors encountered during Read Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally would, including transfer of corrupted data, if any.

Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error reporting is the same as that on a Read Sector(s) Command. This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register.

At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read.

If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer.

Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block which contained the error.

The Read Long command performs similarly to the Read Sector(s) command except that it returns 516 bytes of data instead of 512 bytes. During a Read Long command, the FlashDrive does not check the ECC bytes to determine if there has been a data error. Only single sector read long operations are

Feature (1) X

This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is issued and after each sector of data (except the last one) has been read by the host, the FlashDrive sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host then reads the 512 bytes of data from the buffer.

At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head, and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer.

Table 6-5 Features Supported

Feature Operation

01H Enable 8 bit data transfer. 55H Disable Read Look Ahead. 66H Disable Power on Reset (POR) establishment of defaults at Soft Reset. 69H Accepted for backward compatibility with the SDI Series but has no impact on the FlashDrive. 81H Disable 8 bit data transfer. 96H Accepted for backward compatibility with the SDI Series but has no impact on the FlashDrive. 9AH Set the host current source capability. Allows tradeoff between current drawn and read/write speed. BBH 4 bytes of data apply on Read/Write Long commands. CCH Enable Power on Reset (POR) establishment of defaults at Soft Reset.

Features 01H and 81H are used to enable and clear 8 bit data transfer mode. If the 01H feature command is issued, all data transfers will occur on the low order D7-D0 data bus and the IOIS16 signal will not be asserted for data register accesses.

Features 55H and BBH are the default features for the FlashDrive; thus, the host does not have to issue this command with these features unless it is necessary for compatibility reasons.

The 9AH Feature is a FlashDrive unique option that provides a mechanism for the host system to adjust how much current the FlashDrive will use. The FlashDrive reduces the current it draws by reducing its operating frequency. This has the impact of also reducing the performance of the FlashDrive. The default for the FlashDrive after a power on reset is to operate at the highest performance and therefore the highest current mode. However after a power on, the FlashDrive will not draw more than its minimum current as long as the host does not issue any command which reads or writes to the flash memory. This allows the host to issue the Set Features command to set the desired power level without exceeding the minimum requirement of the FlashDrive.

To reduce the current the FlashDrive draws, the host issues the Set Features command with the Feature register set to 9AH and the Sector Count register (Config) set to a current value which is equal to 4 mA times the value in the Sector Count register. When this is done, the controller will utilize a look-up table to program the controller’s frequency, microprocessor’s speed and flash clocks with an optimum value to provide the highest performance without exceeding the host’s current

limit. For example, if a host can supply 75 mA of

current to the FlashDrive, the Sector Count

down) or a value of 18. The FlashDrive would

then automatically reduce its clock frequencies so

that it will not draw more than 75 mA (average,

at nominal Vcc and room temperature) of current.

If the host always wanted to operate at the

lowest possible current the Sector Count value

should be set to 1. The FlashDrive will then

operate at the lowest possible current (and also

the lowest performance).

At the completion of this command, the controller

will update the Cylinder Low register with the

controller’s minimum valid current value (i.e. the

minimum current with which the FlashDrive can

operate) and the Cylinder High register with the

maximum current it will use (i.e. the maximum

current the FlashDrive will draw at the highest

performance level). The controller will use its

minimum value for any Sector Count value which

is less than its minimum value. For example, if

the Sector Count is set to 4 which is equivalent to

16 mA, the controller will operate at the lowest

possible power point but will not reject the

command. Similarly the controller will use its

maximum value for any Sector Count value which

is more than the maximum current it can use.

There is no error associated with the 9AH feature.

Features 66H and CCH can be used to enable and

disable whether the Power On Reset (POR)

Defaults will be set when a soft reset occurs. The

default setting is to revert to the POR defaults

when a soft reset occurs. POR defaults the number

of heads and sectors along with 16 bit data

transfers and the read/write multiple block count.

Future versions may support larger block sizes. Upon receipt of the command, the FlashDrive sets BSY to 1 and checks the Sector Count Register.

This command causes the FlashDrive to set BSY, enter the Sleep mode, clear BSY and generate an interrupt. Recovery from sleep mode is accomplished by simply issuing another command (a reset is permitted but not required). Sleep mode is also entered when internal timers expire so the

host does not need to issue this command except

when it wishes to enter Sleep mode immediately.

The default value for the read to sleep timer is 5

milliseconds. Note that this time base (5 msec) is

different from the ATA/IDE Specification.

This command is provided for compatibility purposes and is similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes. Only single sector Write Long operations are supported. The transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of ECC transferred in byte

mode. Because of the unique nature of the solidstate FlashDrive, the four bytes of ECC transferred by the host cannot be used by the FlashDrive. The FlashDrive discards these four bytes and writes the sector with valid ECC fields. This command has the same protocol as the Write Sector(s) command.

supports a block count of 1 as indicated in the Identify Drive Command information. This command is provided for compatibility with future products which may support a larger block count.

This command is similar to the Write Sectors command. The FlashDrive sets BSY within 400 nsec of accepting the command. Interrupts are not presented on each sector but on the transfer of a

block which contains the number of sectors defined by Set Multiple. Command execution is identical to the Write Sectors operation except that the number of sectors defined by the Set Multiple command is transferred without intervening interrupts.

DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without

Page 57

FlashDrive Product Manual

intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Write Multiple command.

When the Write Multiple command is issued, the 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 are disabled, the Write Multiple operation will be rejected with an aborted command error.

6.1.27 Write Multiple without Erase - CDH

Errors encountered during Write Multiple commands are posted after the attempted 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 the beginning of each block or partial block.

The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred and the Sector Count Register contains the residual number 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 the third sector.

This command writes from 1 to 256 sectors as specified in the Sector Count Register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is accepted, the FlashDrive sets BSY, then sets DRQ and clears
