Note: 1) These signals are required only for 16 bit accesses and not required when installed in 8 bit systems. Devices should allow for 3-state
signals not to consume current.
2) The signal should be grounded by the host.
3) The signal should be tied to VCC by the host.
4) The mode is required for CompactFlash Storage Cards.
5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled upon the card in these modes,
it should not be left floating by the host in PC Card modes. In these modes, the pin should be connected by the host to PC
Card A25 or grounded by the host.
6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA
operations are not active, the card shall ignore this signal,including a floating condition

These input signals are used both to select the card and to indicate to the card
whether a byte or a word operation is being performed. -CE2 always accesses
the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the
word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1,
-CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29,
Table 31, Table 35, Table 36 and Table 37.
This signal is the same as the PC Card Memory Mode signal.
In the True IDE Mode, -CS0 is the address range select for the task file
registers while -CS1 is used to select the Alternate Status Register and the
Device Control Register.
While –DMACK is asserted, -CS0 and –CS1 shall be held negated and the

O43 This signal is not used in this mode.
The Input Acknowledge signal is asserted by the CompactFlash Storage 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 CompactFlash Storage Card and the CPU.
Hosts that support a single socket per interface logic, such as for Advanced
Timing Modes and Ultra DMA operation may ignore the –INPACK signal from the
device and manage their input buffers based solely on Card Enable signals.
This signal is a DMA Request that is used for DMA data transfers between host
and device. It shall be asserted by the device when it is ready to transfer data to
or from the host. For Multiword DMA transfers, the direction of data transfer is
controlled by -HIOE and -IOWR. This signal is used in a handshake manner with
(-)DMACK, i.e., the device shall wait until the host asserts (-)DMACK before
negating (-)DMARQ, and re-asserting (-)DMARQ if there is more data to
transfer.
In PCMCIA I/O Mode, the
performing an I/O Read cycle to the device. The host shall not initiate an I/O
Read cycle while
In True IDE Mode, DMARQ shall not be driven when the device is not selected in
the Drive-Head register.
While a DMA operation is in progress, -CS0 (-CE1)and -CS1 (-CE2) shall be held
negated and the width of the transfers shall be 16 bits.
If there is no hardware support for True IDE DMA mode in the host, this output
signal is not used and should not be connected at the host. In this case, the BIOS
must report that DMA mode is not supported by the host so that device drivers
will not attempt DMA mode operation.
A host that does not support DMA mode and implements both PC Card and True
IDE modes of operation need not alter the PC Card mode connections while in
True IDE mode as long as this does not prevent proper operation in any mode.
I 34 This signal is not used in this mode.
This is an I/O Read strobe generated by the host. This signal gates I/O data onto
the bus from the CompactFlash Storage Card when the card is configured to use
the I/O interface.
In True IDE Mode, while Ultra DMA mode is not active, this signal has the same
function as in PC Card I/O Mode.
In all modes when Ultra DMA mode DMA Read is active, this signal is asserted
by the host to indicate that the host is ready to receive Ultra DMA data-in bursts.
The host may negate – HDMARDY to pause an Ultra DMA transfer.
In all modes when Ultra DMA mode DMA Write is active, this signal is the data
out strobe generated by the host. Both the rising and falling edge of HSTROBE
cause data to be latched by the device. The host may stop generating
HSTROBE edges to pause an Ultra DMA data-out burst.
-DMARQ is asserted by the device.
-DMARQ shall be ignored by the host while the host is
The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the
CompactFlash Storage Card controller registers when the CompactFlash
Storage Card is configured to use the I/O interface.
The clocking shall occur on the negative to positive edge of the signal (trailing
edge).
In True IDE Mode, while Ultra DMA mode protocol is not active, this signal has
the same function as in PC Card I/O Mode. When Ultra DMA mode protocol is
supported, this signal must be negated before entering Ultra DMA mode
protocol.
In All Modes, while Ultra DMA mode protocol is active, the assertion of this signal
causes the termination of the Ultra DMA data burst.
This is an Output Enable strobe generated by the host interface. It is used to read
data from the CompactFlash Storage Card in Memory Mode and to read the CIS
and configuration registers.
In PC Card I/O Mode, this signal is used to read the CIS and configuration
registers.
To enable True IDE Mode this input should be grounded by the host.
In Memory Mode, this signal is set high when the CompactFlash Storage Card is
ready to accept a new data transfer operation and is held low when the card is
busy.
At power up and at Reset, the READY signal is held low (busy) until the
CompactFlash Storage Card has completed its power up or reset function. No
access of any type should be made to the CompactFlash Storage Card during
this time.
Note, however, that when a card is powered up and used with RESET
continuously disconnected or asserted, the Reset function of the RESET pin is
disabled. Consequently, the continuous assertion of RESET from the application
of power shall not cause the READY signal to remain continuously in the busy
state.
I/O Operation – After the CompactFlash Storage Card 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.
In True IDE Mode signal is the active high Interrupt Request to the host.

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.
In PC Card Memory Mode, when Ultra DMA Protocol is supported by the host
and the host has enabled Ultra DMA protocol on the card the, host shall keep the
-REG signal negated during the execution of any DMA Command by the device.
The signal shall also be active (low) during I/O Cycles when the I/O address is on
the Bus.
In PC Card I/O Mode, when Ultra DMA Protocol is supported by the host and the
host has enabled Ultra DMA protocol on the card the, host shall keep the -REG
signal asserted during the execution of any DMA Command by the device.
This is a DMA Acknowledge signal that is asserted by the host in response to
(-)DMARQ to initiate DMA transfers.
In True IDE Mode, while DMA operations are not active, the card shall ignore the
(-)DMACK signal, including a floating condition.
If DMA operation is not supported by a True IDE Mode only host, this signal
should be driven high or connected to VCC by the host.
A host that does not support DMA mode and implements both PC Card and
True-IDE modes of operation need not alter the PC Card mode connections
while in True-IDE mode as long as this does not prevent proper operation all
modes.

application of power without causing a continuous Reset of the card. Under
either of these conditions, the card shall emerge from power-up having
completed an initial Reset.
The CompactFlash Storage Card is also Reset when the Soft Reset bit in the
Card Configuration Option Register is set.

Voltage Sense Signals. -VS1 is grounded on the Card and sensed by the Host so
that the CompactFlash Storage Card CIS can be read at 3.3 volts and -VS2 is
reserved by PCMCIA for a secondary voltage and is not connected on the Card.
This signal is the same for all modes.
This signal is the same for all modes.
The -WAIT signal is driven low by the CompactFlash Storage Card to signal the
host to delay completion of a memory or I/O cycle that is in progress.
This signal is the same as the PC Card Memory Mode signal.
In True IDE Mode, except in Ultra DMA modes, this output signal may be used as
IORDY.
In all modes, when Ultra DMA mode DMA Write is active, this signal is asserted
by the device during a data burst to indicate that the device is ready to receive
Ultra DMA data out bursts. The device may negate -DDMARDY to pause an
Ultra DMA transfer.
In all modes, when Ultra DMA mode DMA Read is active, this signal is the data in
strobe generated by the device. Both the rising and falling edge of DSTROBE
cause data to be latched by the host. The device may stop generating

Ultra DMA Electrical Requirements
¾ Host and Card signal capacitance limits for Ultra DMA operation
The host interface signal capacitance at the host connector shall be a maximum of 25 pF for each signal as measured at
1 MHz.
The card interface signal capacitance at the card connector shall be a maximum of 20 pF for each signal as measured at
1 MHz.
¾Series termination required for Ultra DMA operation
Series termination resistors are required at both the host and the card for operation in any of the Ultra DMA modes. Table
describes typical values for series termination at the host and the device.
-RESET 33 ohm 82 ohm
NOTE − Only those signals requiring termination are listed in this table. If a signal is not listed, series
termination is not required for operation in an Ultra DMA mode. Shows signals also requiring a pull-up or
pull-down resistor at the host. The actual termination values should be selected to compensate for transceiver
and trace impedance to match the characteristic cable impedance.

¾Printed Circuit Board (PCB) Trace Requirements for Ultra DMA
On any PCB for a host or device supporting Ultra DMA:
9The longest D[15:00] trace shall be no more than 0.5" longer than either STROBE trace as measured from the
IC pin to the connector.
9The shortest D[15:00] trace shall be no more than 0.5" shorter than either STROBE trace as measured from
the IC pin to the connector.
¾Ultra DMA Mode Cabling Requirement
Operation in Ultra DMA mode requires a crosstalk suppressing cable. The cable shall have a grounded line
9
between each signal line.
9
For True IDE mode operation using a cable with IDE (ATA) type 40 pin connectors it is recommended that the
host sense the cable type using the method described in the ANSI INCITS 361-2002 AT Attachment - 6
standard, to prevent use of Ultra DMA with a 40 conductor cable.
