1. Introduction to Standard Grade Flash Storage
Products
The SanDisk CompactFlash® Memory Card (CF) and PC Card products provide high capacity solid-state flash
memory that electrically complies with the Personal Computer Memory Card International Association (PCMCIA)
ATA (PC Card ATA) standard. (In Japan, the applicable standards group is JEIDA.) The CompactFlash and
PCMCIA cards support True IDE Mode that is electrically compatible with an IDE disk drive. 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.
All Standard Grade ATA Flash Storage products use SanDisk Flash memory and are designed by SanDisk
specifically for use in mass storage applications. In addition to the mass storage specific Flash memory chips, the
Standard ATA products 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 the memory card to read or write blocks of
memory. The host addresses the card in 512 byte sectors. Each sector is protected by a powerful Error Correcting
Code (ECC).
The Standard ATA product’s 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 Standard ATA
product 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.
Figure 1-1 is a system block diagram; see Section 2 for detailed specifications.

This manual describes specific characteristics of SanDisk CompactFlash and PC Cards. When designing host
systems, SanDisk strongly recommends conforming to the specifications of the appropriate industry standards (CFA,
PCMCIA or ATA specification) as SanDisk specifications may vary with the introduction of new technologies.
SanDisk always guarantees that our products will meet the appropriate industry specification.
1.2. Product Models

1.7. Functional Description
Standard Grade products contain a high 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 the following:
•
•
•
•
•
Standard ATA register and command set (same as found on most magnetic disk drives).
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 error correction code (ECC).
Power management for low power operation.
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION

1.7.1. Technology Independence
The 512-byte sector size of the Standard Grade product is the same as that 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
card. This command contains the address and the number of sectors 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 card 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 the Standard ATA products today will be able to
access future SanDisk cards built with new flash technology without having to update or change host software.
1.7.2. Defect and Error Management
Standard ATA products 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. If necessary the cards 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 soft-error rate for Standard ATA products is much lower than the magnetic disk drive specification. In the
extremely rare case a read error does occur, the card has innovative algorithms to recover the data.
These defect and error management systems, coupled with the solid-state construction, give SanDisk Standard ATA
products unparalleled reliability.
1.7.3. Wear Leveling
Wear Leveling is an intrinsic part of the operation of SanDisk products using NAND memory. The CF WEAR
LEVEL command is supported as a NOP operation to maintain backward compatibility with existing software
utilities.
1.7.4. Using the Erase Sector and Write without Erase Commands
SanDisk Standard ATA products support the ERASE SECTOR and WRITE WITHOUT ERASE commands. In
some applications, write operations may be faster if the addresses being written are first erased with the ERASE
SECTORS command. WRITE WITHOUT ERASE behaves as a normal write command and no performance gain
results from its use.
1.7.5. Automatic Sleep Mode
A unique feature of the SanDisk CompactFlash Memory card (and other SanDisk products) is automatic entrance
and exit from sleep mode. Upon completion of a command, the card will enter 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 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.
4
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION
When the host is ready to access the card and it is in sleep mode, any command issued to the 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 the SanDisk product, as other ATA products may not support this feature.
1.7.6. Dynamic Adjustment of Performance versus Power Consumption
This feature is no longer supported. This command will be treated as a NOP (No Operation) to guarantee backward
compatibility.
1.7.7. Power Supply Requirements
This is a dual voltage product, which means it will operate at a voltage range of 3.30 volts ± 10% or 5.00 volts ±
10%. Per the PCMCIA specification Section 2.1.1, the host system must apply 0 volts in order to change a voltage
range. This same procedure of providing 0 volts to the card is required if the host system applies an input voltage
outside the desired voltage by more than 15%. This means less than 4.25 volts for the 5.00 volt range and less than
2.75 volts for the 3.30 volt range.

NOTE: 1. These signals are required only for 16-bit access and not required when installed in 8-bit systems. For lowest power
dissipation, leave these signals open.
2. Should be grounded by the host.
3. Should be tied to VCC by the host.
4. Refer to Section 3.3 for definitions of In, Out type.
5. CompactFlash products support multiword DMA in anticipation of the CF Specification 2.1 release. CompactFlash
products without DMA Support are available from SanDisk.
3.2. Electrical Description
The CompactFlash and PCMCIA cards are optimized for operation with hosts that support the PCMCIA I/O
interface standard conforming to the PC Card ATA specification. However, the CompactFlash and PCMCIA cards
may also be configured to operate in systems that support only the memory interface standard. The configuration of
the CompactFlash and PCMCIA cards are controlled using the standard PCMCIA configuration registers starting at
address 200h in the Attribute Memory space of the CompactFlash Memory Card.
Table 3-3 describes the I/O signals. Signals are designated as inputs when their source is the host, while signals that
the CompactFlash Memory Card sources are outputs. The CompactFlash Card logic levels conform to those
specified in the PCMCIA Release 2.1 Specification. See Section 3.3 for definitions of Input and Output type.

Description
This signal is not used in this mode.
-INPACK
(PC Card I/O Mode)
Input Acknowledge
The Input Acknowledge signal is asserted by the CompactFlash Card when the card is selected and
responding to an I/O read cycle at the address that is on the address bus. This signal is used by the
host to control the enable of any input data buffers between the card and the CPU.
DMARQ1
(True IDE Mode)
This signal is used for DMA data transfers between host and device and is asserted by the device when
it is ready to transfer data to or from the host. The direction of data transfer is controlled by DIOR- and
DIOW-. This signal is used in a handshake manner with DMACK- (i.e., the device waits until the host
asserts DMACK- before negating DMARQ, and reasserting DMARQ if there is more data to transfer).
-IORD
(PC Card Memory Mode)
I
This signal is not used in this mode.
-IORD
(PC Card I/O Mode)
This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the
CompactFlash Card when the card is configured to use the I/O interface.
-IORD
(True IDE Mode)
In True IDE Mode, this signal has the same function as in PC Card I/O Mode.
-IOWR
(PC Card Memory Mode)
I
-IOWR
(PC Card I/O Mode)
This signal is not used in this mode.
The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the CompactFlash
controller registers when the card is configured to use the I/O interface.
The clocking will occur on the negative to positive edge of the signal (trailing edge).
-IOWR
(True IDE Mode)
-OE
(PC Card Memory Mode)
In True IDE Mode, this signal has the same function as in PC Card I/O Mode.
I
This is an Output Enable strobe generated by the host interface. It is used to read data from the
CompactFlash Card in Memory Mode and to read the CIS and configuration registers.
-OE
(PC Card I/O Mode)
In PC Card I/O Mode, this signal is used to read the CIS and configuration registers.
-ATA SEL
(True IDE Mode)
To enable True IDE Mode this input should be grounded by the host.
RDY/-BSY
(PC Card Memory Mode)
O
In Memory Mode this signal is set high when the CompactFlash Card is ready to accept a new data
transfer operation and held low when the card is busy. The Host memory card socket must provide a
pull-up resistor.
At power up and at Reset, the RDY/-BSY signal is held low (busy) until the CompactFlash Card has
completed its power up or reset function. No access of any type should be made to the CompactFlash
Card during this time. The RDY/-BSY signal is held high (disabled from being busy) whenever the
following condition is true: The CompactFlash Card has been powered up with +RESET continuously
disconnected or asserted.
-IREQ
(PC Card I/O Mode)
I/O Operation—After the CompactFlash Card has been configured for I/O operation, this signal is used
as -Interrupt Request. This line is strobed low to generate a pulse mode interrupt or held low for a level
mode interrupt.
INTRQ
(True IDE Mode)
In True IDE Mode, this signal is the active high Interrupt Request to the host.

Description
This signal is used during Memory Cycles to distinguish between Common Memory and Register
(Attribute) Memory accesses. High for Common Memory, Low for Attribute Memory.
-REG
(PC Card I/O Mode)
The signal must also be active (low) during I/O Cycles when the I/O address is on the Bus.
-DMACK1
(True IDE Mode)
The host uses this signal in response to DMARQ to initiate DMA transfers.
RESET
(PC Card Memory Mode)
NOTE: This signal may be negated by the host to suspend the DMS transfer in process. For Multiword
DMA transfers, the device may negate DMARQ with the tL specified time once the DMACK- is asserted
and reasserted again at a later time to resume DMA operation. Alternatively, if the device is able to
continue the data transfer, the device may leave DMARQ asserted and wait for the host to reassert
DMACK-.
I
When the pin is high, this signal resets the CompactFlash Card. The card is Reset only at power up if
this pin is left high or open from power-up. The card is also reset when the Soft Reset bit in the Card

3.3.12. True IDE Mode
The following sections provide valuable information for the True IDE mode.
3.3.12.1. De-skewing
The host shall provide cable de-skewing for all signals originating from the device. The device shall provide cable
de-skewing for all signals originating at the host.
All timing values and diagrams are shown and measured at the connector of the selected device.
3.3.12.2. PIO Transfer Timing
The minimum cycle time supported by Standard Grade devices in PIO mode 4 and Multiword DMA mode 2
respectively shall always be greater than or equal to the minimum cycle time defined by the associated mode.
Register Transfers
Figure 3-8 defines the relationships between the interface signals for register transfers.
For PIO modes 3 and above, the minimum value of t0 is specified by word 68 in the IDENTIFY DEVICE parameter
list. In Table 3-15, t0 is the minimum total cycle time, t2 is the minimum command active time, and t2i is the
minimum command recovery time or command inactive time. The actual cycle time equals the sum of the actual
command active time and the actual command inactive time. The three timing requirements f t0, t2, and t2i will be
met. The minimum total cycle time requirements are greater than the sum of t2 and t2i. This means a host
implementation may lengthen either or both t2 or t2i to ensure that t0 is equal to or greater than the value reported in
the devices IDENTIFY DEVICE data. A device implementation will support any legal host implementation.
The IORD-data tri-state parameter specifies the time from the negation edge of /IORD to the time that the data bus
is no longer driven by the device (tri-state).
Table 3-14 defines the minimum value that shall be placed in word 68.

3.3.12.3. Multiword DMA Data Transfer Timing
SanDisk PCMCIA products support Multiword DMA operation in IDE mode (see Figure 3-10). The timings
associated with Multiword DMA Transfers are defined in Table 3-17. CompactFlash products now support
multiword DMA in anticipation of the CF Specification Rev. 2.1 release.
Figure 3-10. Multiword DMA Transfer
32
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION
In Table 3-17, t0 is the minimum total cycle time, t2 is the minimum command active time, and t2i is the minimum
command recovery time or command inactive time. The actual cycle time equals the sum of the actual command
active time and the actual command inactive time. The three timing requirements of t0, t2, and t2i shall be met. The
minimum total cycle time requirements are greater than the sum of t2 and t2i. This means a host implementation
may lengthen either or both t2 or t2i to ensure that t0 is equal to or greater than the value reported in the devices
IDENTIFY DEVICE data. A device implementation shall support any legal host implementation.
The IORD-data tri-state parameter specifies the time from the negation edge of /IORD to the time that the data bus
is no longer driven by the device (tri-state).

3.4. Card Configuration
The CompactFlash Memory Cards are identified by appropriate information in the Card Information Structure (CIS).
The configuration registers in Table 3-17 and Table 3-18 are used to coordinate the I/O spaces and the Interrupt
level of cards that are located in the system. In addition, these registers provide a method for accessing status
information about the CompactFlash Card that may be used to arbitrate between multiple interrupt sources on the
same interrupt level or to replace status information that appears on dedicated pins in memory cards that have
alternate use in I/O cards.

3.4.1. Attribute Memory Function
Attribute memory is a space where CompactFlash Memory Card identification and configuration information is
stored, and is limited to 8-bit wide accesses only at even addresses. The card configuration registers are also located
here.
For the Attribute Memory Read function, signals -REG and -OE must be active and -WE inactive during the cycle.
As in the Main Memory Read functions, the signals -CE1 and -CE2 control the even-byte and odd-byte address, but
only the even-byte data is valid during the Attribute Memory access. Refer to Table 3-19 for signal states and bus
validity for the Attribute Memory function.

Soft Reset—Setting this bit to one (1), waiting the minimum reset width time and returning to zero (0)
places the CompactFlash Memory Card in the Reset state. Setting this bit to one (1) is equivalent to
assertion of the +RESET signal except that the SRESET bit is not cleared. Returning this bit to zero (0)
leaves the CompactFlash Memory Card in the same un-configured, Reset state as following power-up and
hardware reset. This bit is set to zero (0) by power-up and hardware reset. Using the PC Card Soft Reset is
considered a hard Reset by the ATA Commands. Contrast with Soft Reset in the Device Control Register.
This bit is set to one (1) when Level Mode Interrupt is selected, and zero (0) when Pulse Mode is selected.
Set to zero (0) by Reset.

Indicates that one or both of the Pin Replacement register CRdy, or CWProt bits are set to one (1). When the
Changed bit is set, -STSCHG Pin 46 is held low if the SigChg bit is a One (1) and the CompactFlash Memory
Card is configured for the I/O interface.
SigChg
This bit is set and reset by the host to enable and disable a state-change “signal” from the Status Register, the
Changed bit control pin 46 the Changed Status signal. If no state change signal is desired, this bit should be
set to zero (0) and pin 46 (-STSCHG) signal will be held high while the CompactFlash Memory Card is
configured for I/O.
IOis8
The host sets this bit to a one (1) if the CompactFlash Memory Card is to be configured in an 8-bit I/O mode.
The CompactFlash Card is always configured for both 8- and 16-bit I/O, so this bit is ignored.
36
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION
PwrDwn
This bit indicates whether the host requests the CompactFlash Memory Card to be in the power saving or
active mode. When the bit is one (1), the CompactFlash Card enters a power down mode. When zero (0), the
host is requesting the CompactFlash Card to enter the active mode. The PC Card Rdy/-Bsy value becomes
BUSY when this bit is changed. Rdy/-Bsy will not become Ready until the power state requested has been
entered. The CompactFlash Card automatically powers down when it is idle and powers back up when it
receives a command.
Int
This bit represents the internal state of the interrupt request. This value is available whether or not I/O
interface has been configured. This signal remains true until the condition that caused the interrupt request

3.5. I/O Transfer Function
The I/O transfer to or from the CompactFlash Memory Card can be either 8 or 16 bits. When a 16-bit accessible port
is addressed, the signal -IOIS16 is asserted by the CompactFlash Card. Otherwise, the -IOIS16 signal is de-asserted.
When a 16-bit transfer is attempted, and the -IOIS16 signal is not asserted by the CompactFlash Card, the system
must generate a pair of 8-bit references to access the word‘s even byte and odd byte. The CompactFlash Card
permits both 8- and 16-bit accesses to all of its I/O addresses, so -IOIS16 is asserted for all addresses to which the
CompactFlash Card responds (refer to Table 3-25).

3.7. True IDE Mode I/O Transfer Function
The CompactFlash or PCMCIA card can be configured in a True IDE Mode of operation. This CompactFlash or
PCMCIA card is configured in this mode only when the -OE input signal is grounded by the host when power is
applied to the card. In True IDE Mode, the PC Card protocol and configuration are disabled and only I/O operations
to the Task File and Data Register are allowed. In addition, No Memory or Attribute Registers are accessible to the
host. SanDisk products permit 8 bit data accesses if the user issues a Set Feature Command to put the device in 8-bit
Mode.
NOTE: Removing and reinserting the CompactFlash Memory Card while the host computer’s power is on will
reconfigure the CompactFlash Card to PC Card ATA mode from the original True IDE Mode. To configure the
CompactFlash Card in True IDE Mode, the 50-pin socket must be power cycled with the CompactFlash Card
inserted and -OE (output enable) grounded by the host.
Table 3-27, on the next page, defines the function of the operations for the True IDE Mode.

4. ATA Drive Register Set Definition and Protocol
The CompactFlash Memory Card can be configured as a high performance I/O device through the following ways:
•
•
•
Standard PC-AT disk I/O address spaces 1F0h-1F7h, 3F6h-3F7h (primary); 170h-177h, 376h-377h
(secondary) with IRQ 14 (or other available IRQ).
Any system decoded 16-byte I/O block using any available IRQ.
Memory space.
The communication to or from the CompactFlash Memory Card is done using the Task File registers, which provide
all the necessary registers for control and status information. The PC Card interface connects peripherals to the host
using four register mapping methods. Table 4-1 is a detailed description of these methods.

1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a word register on the combined
Odd Data Bus and Even Data Bus (D15-D0). This register may also be accessed by a pair of byte accesses to the
offset 0 with -CE1 low and -CE2 high. Note that the address space of this word register overlaps the address space
of the Error and Feature byte-wide registers that lie at offset 1. When accessed twice as byte register with -CE1 low,
the first byte to be accessed is the even byte of the word and the second byte accessed is the odd byte of the
equivalent word access.
2. A byte access to register 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register.
4.2. Contiguous I/O Mapped Addressing
When the system decodes a contiguous block of I/O registers to select the CompactFlash Memory Card, the registers
are accessed in the block of I/O space decoded by the system in Table 4-3.

NOTES: 1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a word register on the combined Odd
Data Bus and Even Data Bus (D15-D0). This register may also be accessed by a pair of byte accesses to the offset 0
with -CE1 low and -CE2 high. Note that the address space of this word register overlaps the address space of the Error
and Feature byte-wide registers that lie at offset 1. When accessed twice as byte register with -CE1 low, the first byte to
be accessed is the even byte of the word and the second byte accessed is the odd byte of the equivalent word access.
A byte access to register 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register.
2. Registers at offset 8, 9 and D are non-overlapping duplicates of the registers at offset 0 and 1.
Register 8 is equivalent to register 0, while register 9 accesses the odd byte. Therefore, if the registers are byte accessed
in the order 9 then 8 the data will be transferred odd byte then even byte.
Repeated byte accesses to register 8 or 0 will access consecutive (even than odd) bytes from the data buffer. Repeated
word accesses to register 8, 9 or 0 will access consecutive words from the data buffer. Repeated byte accesses to
register 9 are not supported. However, repeated alternating byte accesses to registers 8 then 9 will access consecutive
(even then odd) bytes from the data buffer. Byte accesses to register 9 access only the odd byte of the data.
3. Address lines that are not indicated are ignored by the CompactFlash Memory Card for accessing all the registers in
this table.

3. Accesses to even addresses between 400h and 7FFh access register 8. Accesses to odd addresses between 400h and
7FFh access register 9. This 1 KByte memory window to the data register is provided so that hosts can perform
memory to memory block moves to the data register when the register lies in memory space.
Some hosts, such as the X86 processors, must increment both the source and destination addresses when executing the
memory to memory block move instruction. Some PC Card socket adapters also have auto incrementing address logic
embedded within them. This address window allows these hosts and adapters to function efficiently.
Note that this entire window accesses the Data Register FIFO and does not allow random access to the data buffer
within the CompactFlash Memory Card.

4.5. ATA Registers
NOTE: In accordance with the PCMCIA specification: each of the registers below which is located at an odd offset
address may be accessed at its normal address and also the corresponding even address (normal address -1)
using data bus lines (D15-D8) when -CE1 is high and -CE2 is low unless -IOIS16 is high (not asserted) and
an I/O cycle is being performed.
4.5.1. Data Register (Address—1F0[170];Offset 0, 8, 9)
The Data Register is a 16-bit register, and it is used to transfer data blocks between the Standard ATA product data
buffer and the Host. This register overlaps the Error Register. Table 4-6 describes the combinations of data register
access and is provided to assist in understanding the overlapped Data Register and Error/Feature Register rather than
to attempt to define general PCMCIA word and byte access modes and operations. See the PCMCIA PC Card
Standard Release 2.0 for definitions of the Card Accessing Modes for I/O and Memory cycles.
NOTE: Because of the overlapped registers, access to the 1F1, 171 or offset 1 are not defined for word (-CE2 = 0
and -CE1 = 0) operations. SanDisk products treat these accesses as accesses to the Word Data Register. The
duplicated registers at offsets 8, 9 and Dh have no restrictions on the operations that can be performed by
the socket.

4.5.3. Feature Register (Address—1F1[171]; Offset 1, 0Dh Write Only
This register provides information regarding features of the Standard ATA product that the host can utilize. This
register is also accessed on data bits D15-D8 during a write operation to Offset 0 with -CE2 low and -CE1 high
(except in True IDE Mode operation).
4.5.4. Sector Count Register (Address—1F2[172]; Offset 2)
This register contains the number of sectors of data requested to be transferred on a read or write operation between
the host and the CompactFlash Memory Card. If the value in this register is zero, a count of 256 sectors is specified.
If the command was successful, this register is zero at command completion. If not successfully completed, the
register contains the number of sectors that need to be transferred in order to complete the request.

Logical Block Mode, the Logical Block Address is interpreted as follows:
LBA07-LBA00: Sector Number Register D7-D0.
LBA15-LBA08: Cylinder Low Register D7-D0.
LBA23-LBA16: Cylinder High Register D7-D0.
LBA27-LBA24: Drive/Head Register bits HS3-HS0.
This bit is set to 1.
This bit will have the following meaning. DRV is the drive number. When DRV=0, drive (card) 0 is selected
When DRV=1, drive (card) 1 is selected. In PCMCIA Mode operation, Card 0 or 1 is selected using the copy
field of the PC Card Socket and Copy configuration register.
When operating in the Cylinder, Head, Sector mode, this is bit 3 of the head number. It is Bit 27 in the
Logical Block Address mode.
When operating in the Cylinder, Head, Sector mode, this is bit 2 of the head number. It is Bit 26 in the
Logical Block Address mode.
When operating in the Cylinder, Head, Sector mode, this is bit 1 of the head number. It is Bit 25 in the
Logical Block Address mode.
When operating in the Cylinder, Head, Sector mode, this is bit 0 of the head number. It is Bit 24 in the
Logical Block Address mode.

4.5.9. Status and Alternate Status Registers (Address 1F7[177] and 3F6[376];
Offsets 7 and Eh)
These registers return the status when read by the host. Reading the Status register does clear a pending interrupt
while reading the Auxiliary Status register does not. The meaning of the status bits are described as follows:
D7
D6
D5
D4
D3
D2

Bit 6 (RDY)
Bit 5 (DWF)
Bit 4 (DSC)
Bit 3 (DRQ)
Bit 2 (CORR)
Bit 1 (IDX)
Bit 0 (ERR)
The busy bit is set when the Standard ATA product has access to the command buffer and registers and the
host is locked out from accessing the command register and buffer. No other bits in this register are valid
when this bit is set to a 1.
RDY indicates whether the device is capable of performing operations requested by the host. This bit is
cleared at power up and remains cleared until the Standard ATA product is ready to accept a command.
This bit, if set, indicates a write fault has occurred.
This bit is set when the Standard ATA product is ready.
The Data Request is set when the Standard ATA product requires that information be transferred either to or
from the host through the Data register.
This bit is set when a Correctable data error has been encountered and the data has been corrected. This
condition does not terminate a multi-sector read operation.
This bit is always set to 0.
This bit is set when the previous command has ended in some type of error. The bits in the Error register
contain additional information describing the error.
4.5.10. Device Control Register (Address—3F6[376]; Offset Eh)
This register is used to control the card interrupt request and to issue an ATA soft reset to the card. The bits are
defined as follows:

This bit is set to 1 in order to force the card to perform an AT Disk controller Soft Reset operation. This
does not change the PC Card Configuration Registers (4.3.2 to 4.3.5) as a hardware Reset does. The card
remains in Reset until this bit is reset to '0'.
The Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, interrupts from the card are
disabled. This bit also controls the Int bit in the Configuration and Status Register. This bit is set to 0 at
power on and Reset.
This bit is ignored by the card.

4.5.11. Card (Drive) Address Register (Address 3F7[377]; Offset Fh)
This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not
be mapped into the host's I/O space because of potential conflicts on Bit 7. The bits are defined as follows:
D7
D6

Bit 7
This bit is unknown.
Implementation Note:
Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller operating at
the same addresses as the Standard ATA product. Following are some possible solutions to this problem for
the PC Card implementation:
1. Locate the Standard ATA product at a non-conflicting address (i.e., Secondary address (377) or in an
independently decoded Address Space when a Floppy Disk Controller is located at the Primary addresses).
2. Do not install a Floppy and an Standard ATA product in the system at the same time.
3. Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7/377
when an Standard ATA product is installed and conversely to tri-state D6-D0 of I/O address 3F7/377 when a
floppy controller is installed.
4. Do not use the Standard ATA product’s Drive Address register. This may be accomplished by either a) If
possible, program the host adapter to enable only I/O addresses 1F0-1F7, 3F6 (or 170-177, 176) to the
Standard ATA product or b) if provided use an additional Primary/Secondary configuration in the Standard
ATA product that does not respond to accesses to I/O locations 3F7 and 377. With either of these
implementations, the host software must not attempt to use information in the Drive Address Register.
Bit 6 (-WTG)
This bit is 0 when a write operation is in progress, otherwise, it is 1.
Bit 5 (-HS3)
This bit is the negation of bit 3 in the Drive/Head register.
Bit 4 (-HS2)
This bit is the negation of bit 2 in the Drive/Head register.
Bit 3 (-HS1)
This bit is the negation of bit 1 in the Drive/Head register.
Bit 2 (-HS0)
This bit is the negation of bit 0 in the Drive/Head register.
Bit 1 (-nDS1)
This bit is 0 when drive 1 is active and selected.
Bit 0 (-nDS0)
This bit is 0 when the drive 0 is active and selected.

5. ATA Command Description
This section defines the software requirements and the format of the commands the host sends to the Standard ATA
products. Commands are issued 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 5-1) of command acceptance, all dependent on the host not
issuing commands unless the card is not busy. (The BUSY bit in the status and alternate status registers is 0.)
•
•
•
Upon receipt of a Class 1 command, the card sets the BUSY bit within 400 nsec.
Upon receipt of a Class 2 command, the CompactFlash Memory Card 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 CompactFlash Memory Card sets the BUSY bit within 400
nsec, sets up the sector buffer for a write operation, sets DRQ within 20 msec (assuming no reassignments), and clears the BUSY bit within 400 nsec of setting DRQ.

Note 1:
Note 2:
These commands are not standard ATA commands but provide additional functionality.
These commands are not standard ATA commands and these features are no longer supported with the introduction of
256 Mbit Flash Technology. If one of these commands is issued, the sectors will be erased but there will be no net gain
in write performance when using the Write Without Erase command.
Definitions: FR = Features Register, SC = Sector Count Register, SN = Sector Number Register, CY = Cylinder Registers, DH =
Card/Drive/Head Register, LBA = Logical Block Address Mode Supported (see command descriptions for use).
Y—The register contains a valid parameter for this command. For the Drive/Head Register Y means both the
CompactFlash Card and head parameters are used; D—only the CompactFlash Card parameter is valid and not the head
parameter.

This command writes the desired head and cylinder of the selected drive with an FFh pattern. To remain host
backward compatible, the card expects a sector buffer of data from the host to follow the command with the same
protocol as the Write Sector(s) command although the information in the buffer is not used by the card. If LBA=1
then the number of sectors to format is taken from the Sec Cnt register (0=256).
5.1.5. Identify Drive—ECH
The Identify Drive command in Table 5-7 enables the host to receive parameter information from the card. This
command has the same protocol as the Read Sector(s) command. The parameter words in the buffer have the
arrangement and meanings defined in Table 5-8. All reserved bits or words are zero. Table 5-8 is the definition for
each field in the Identify Drive Information.

5.1.5.17. Word 51: PIO Data Transfer Cycle Timing Mode
The PIO transfer timing for Standard and Extended Temperature products fall into categories that have different
parametric timing specifications. To determine the proper device-timing category, compare the Cycle Time specified
in Table 3-15 with the contents of this field with Table 3-14.
t0 is the minimum total cycle time, t2 is the minimum command active time, and t2i is the minimum command
recovery time or command inactive time. The actual cycle time equals the sum of the actual command active time
and the actual command inactive time. The three timing requirements of t0, t2, and t2i shall be met. The minimum
total cycle time requirements are greater than the sum of t2 and t2i. This means a host implementation may lengthen
either or both t2 or t2i to ensure that t0 is equal to or greater than the value reported in the devices IDENTIFY
DEVICE data. A device implementation shall support any legal host implementation.
The IORD-data tri-state parameter specifies the time from the negation edge of /IORD to the time that the data bus
is no longer driven by the device (tri-state).
NOTE: For backward compatibility with BIOSs written before Word 64 was defined for advanced modes, a device
reports in Word 51 the highest original PIO mode it can support (i.e., PIO mode 0, 1 or 2).
5.1.5.18. Word 52: Single Word DMA Data Transfer Cycle Timing Mode
This field states this product doesn’t support Single Word DMA data transfer mode.
5.1.5.19. Word 53: Translation Parameters Valid
Bit 0 of this field is set, indicating that words 54 to 58 are valid and reflect the current number of cylinders, heads
and sectors. Bit 1 is also set, indicating values in words 64 through 70 are valid.
5.1.5.20. Words 54-56: Current Number of Cylinders, Heads, Sectors/Track
These fields contain the current number of user addressable Cylinders, Heads, and Sectors/Track in the current
translation mode.
5.1.5.21. Words 57-58: Current Capacity
This field contains the product of the current cylinders times heads times sectors.
5.1.5.22. Word 59: Multiple Sector Setting
This field contains a validity flag in the odd byte, and the current number of sectors that can be transferred per
interrupt for R/W Multiple in the even byte. The odd byte is always 01H, which indicates that the even byte is
always valid.
56
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION
The even byte value depends on the value set by the Set Multiple command. The even byte of this word by default
contains a 00H, which indicates that R/W Multiple commands are not valid. The only other value returned by the
card in the even byte is a 01H value, which indicates that 1 sector per interrupt, can be transferred in R/W Multiple
mode.
5.1.5.23. Words 60-61: Total Sectors Addressable in LBA Mode
This field contains the number of sectors addressable for the card in LBA mode only.
5.1.5.24. Word 64: Advanced PIO Transfer Modes Supported
In Standard Temperature products, bits 0 and 1 of this field are set to indicate support for PIO transfer modes 3 and

5.1.5.25. Word 65: Minimum Multiword DMA Transfer Cycle Time per Word
Word 65 of the parameter information of the IDENTIFY DEVICE command is defined as the Minimum Multiword
DMA Transfer Cycle Time Per Word. This field defines, in nanoseconds, the minimum cycle time that the device
can support when performing Multiword DMA transfers on a per word basis.
CompactFlash products support multiword DMA in anticipation of the CF Specification Rev. 2.1 release.
5.1.5.26. Word 66: Recommended Multiword DMA Cycle Time
Word 66 of the parameter information of the IDENTIFY DEVICE command is defined as the Recommended
Multiword DMA Transfer Cycle Time. This field defines, in nanoseconds, the minimum cycle time per word during
a single sector host transfer while performing a multiple sector READ DMA or WRITE DMA commands over all
locations on the media under minimal conditions. If a host runs at a faster cycle rate by operating at a cycle time of
less that this value, the device may negate DMARQ for flow control. The rate at which DMARQ is negated could
result in reduced throughput despite the faster cycled rate. Transfer at this rate does not ensure that flow control will
not be used, but implies that higher performance may result.
CompactFlash products support multiword DMA in anticipation of the CF Specification Rev. 2.1 release.
5.1.5.27. Word 67: Minimum PIO Transfer Cycle Time Without Flow Control
This field indicates in nanoseconds, the minimum cycle time that, if used by the host, the card guarantees data

5.1.6. Idle—97H, E3H
The Idle command in Table 5-9 causes the card to set BSY, enter the Idle (Read) mode, clear BSY and generate an
interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5 milliseconds and
the automatic power down mode is enabled. If the sector count is zero, the automatic power down mode is disabled.
Note that this time base (5 msec) is different from the ATA specification.

•
The host initialises the DMA channel prior to issuing the command.
Data transfers are qualified by DMARQ and are performed by the DMA channel.
The device issues only one interrupt per command to indicate that data transfer has terminated and
status is available.

NOTE: The current revision of the card only supports a block count of 1 as indicated in the Identify Drive
Information command. This command is provided for compatibility with future products that may support a
larger block count.
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.
60
Standard Grade Product Manual, Rev. 1.5 © 2003/2004 SANDISK CORPORATION
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 = (sector count)—module (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 that contained the error.
5.1.12. Read Long Sector—22H, 23H
The Read Long command in Table 5-15 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 card does not check the ECC bytes to
determine if there has been a data error. Only single sector read long operations are supported. The transfer consists
of 512 bytes of data transferred in word mode followed by 4 bytes of random data transferred in byte mode. Random
data is returned instead of ECC bytes because of the nature of the ECC system used. This command has the same
protocol as the Read Sector(s) command.

5.1.13. Read Sector(s)—20H, 21H
The Read Sector(s) command in Table 5-16 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 card
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

The Read Verify Sector(s) command in Table 5-17 is identical to the Read Sectors command, except that DRQ is
never set and no data is transferred to the host. When the command is accepted, the CompactFlash Memory Card
sets BSY.
When the requested sectors have been verified, the card clears BSY and generates an interrupt. Upon command
completion, the Command Block Registers contain the cylinder, head, and sector number of the last sector verified.
If an error occurs, the “verify” terminates at the sector where the error occurs. The Command Block Registers
contain the cylinder, head and sector number of the sector where the error occurred. The Sector Count Register
contains the number of sectors not yet verified.

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 card; thus, the host does not have to issue this command with
these features unless it is necessary for compatibility reasons.
Feature 9AH is accepted for backward compatibility with legacy SanDisk ATA products but has no impact on the
card. SanDisk does not recommend the use of this command in new designs.
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.

The Set Multiple Mode command in Table 5-25 enables the card to perform Read and Write Multiple operations and
establishes the block count for these commands. The Sector Count Register is loaded with the number of sectors per
block. The current version of the card supports only a block size of 1 sector per block. Future versions may support
larger block sizes. Upon receipt of the command, the product sets BSY to 1 and checks the Sector Count Register.

disabled. If the Sector Count Register contains 0 when the command is issued, Read and Write Multiple commands
are disabled. At power on, or after a hardware or (unless disabled by a Set Feature command) software reset, the
default mode is Read and Write Multiple disabled.
5.1.20. Set Sleep Mode- 99H, E6H
The Set Sleep Mode command in Table 5-26 causes the card 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 Specification.

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 solid-state card, the four bytes of ECC transferred by
the host cannot be used by the card. The card discards these four bytes and writes the sector with valid ECC fields.
This command has the same protocol as the Write Sector(s) command.

5.1.28. Write Multiple Command—C5H
The Write Multiple command in Table 5-35 is similar to the Write Sectors command. The card sets BSY within 400
nsec of accepting the command. Interrupts are not presented on each sector but on the transfer of a block that
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.

NOTE: The current revision of the Standard ATA product only supports a block count of 1 as indicated in the
Identify Drive Command information. This command is provided for compatibility with future products
that may support a larger block count.
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 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.
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.

5.1.29. Write Multiple without Erase—CDH
SanDisk does not recommend the use of the Write Multiple without Erase command in new designs but it is
supported as a normal Write Sectors command for backward compatibility reasons.

5.1.30. Write Sector(s)—30H, 31H
The Write Sectors command in Table 5-37 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 card sets BSY, then sets DRQ and clears BSY, then waits for the host to fill the
sector buffer with the data to be written. No interrupt is generated to start the first buffer fill operation. No data
should be transferred by the host until BSY has been cleared by the host.

For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the
next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data
is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which
time BSY is cleared and an interrupt is generated.
If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The
Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The
host may then read the command block to determine what error has occurred, and on which sector.

5.1.32. Write Verify Sector(s)—3CH
The Write Verify Sector(s) command in Table 5-39 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 card sets BSY, then sets DRQ and clears BSY, then waits for
the host to fill the sector buffer with the data to be written. No interrupt is generated to start the first buffer fill
operation. No data should be transferred by the host until BSY has been cleared by the host.

For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the
next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data
is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which
time BSY is cleared and an interrupt is generated.
If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The
Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The
host may then read the command block to determine what error has occurred, and on which sector.

WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION,
ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR
