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

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

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
any input data buffers between the CompactFlash Storage Card and the CPU.
This signal is a DMA Request that is used for DMA data
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 -IORD and -IOWR. This signal is used in a
-DMACK, i.e., the device shall wait until the host asserts -DMACK before
negating DMARQ, and reasserting DMARQ if there is more data to transfer.
DMARQ shall not be driven when the device is not selected.
While a DMA operation is in progress, -CS0 and –CS1 shall be held negated
and the width of the transfers shall be 16 bits.
If there is no hardware support for DMA mode in the host, this
used and should not be connected at the host. In this case
that DMA mode is not supported by the host so that device drivers will not
attempt DMA mode.
A host that does not support DMA mode and implements both PCMCIA and
True-IDE modes of operation need not alter the PCMCIA mode connections

this does not prevent proper operation in any

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.

at a DC current of 700 μA low
state and 150 μA high state, including pull-resistor. The socket shall be able to drive at least the following load
10
while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (50 pF with DC
current 700 μA low state and 150 μA high state per socket).
2) Resistor is optional.
3) Status Signals: the socket shall present a load to the card no larger than 50 pF
10
at a DC current of 400 μA low state
and 100 μA high state, including pull-up resistor. The card shall be able to drive at least the following load

meeting all AC timing requirements: 50 pF at a DC current of 400 μA low state and 100 μA high state.
5) Status Signals: the socket shall present a load to the card no larger than 50 pF
10
at a DC current of 400 μA low state
and 100 μA high state, including pull-up resistor. The card shall be able to drive at least the following load
10
while
meeting all AC timing requirements: 50 pF at a DC current of 400 μA low state and 1100 μA high state.
6) BVD2 was not defined in the JEIDA 3.0 release. Systems fully supporting JEIDA release 3 SRAM cards shall pull-up
pin 45 (BVD2) to avoid sensing their batteries as “Low.”
7) Address Signals: each card shall present a load of no more than 100pF
10
at a DC current of 450μA low state and
150μA high state. The host shall be able to drive at least the following load
10
while meeting all AC timing
requirements: (the number of sockets wired in parallel) multiplied by (100pF with DC current 450μA low state and
150μA high state per socket).
8) Data Signals: the host and each card shall present a load no larger than 50pF
10
at a DC current of 450μA and 150
μ
A high state. The host and each card shall be able to drive at least the following load
10
while meeting all AC
timing requirements: 100pF with DC current 1.6mA low state and 300μA high state. This permits the host to wire
two sockets in parallel without derating the card access speeds.
9) Reset Signal: This signal is pulled up to prevent the input from floating when a CFA to PCMCIA adapter is used in a
PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal operation the
pull-up should be turned off once the Reset signal has been actively driven low by the host. Consequently, the input
is specified as an I2Z because the resistor is not necessarily detectable in the input current leakage test.

total load. All times are in nanoseconds. Minimum time from -IORDY high to -IORD high is 0 nsec, but minimum -IORD width
shall still be met.
1) 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 requirement is greater
than the sum of t2 and t2i. This means a host implementation can lengthen either or both t2 or t2i to ensure that t0 is equal to
or greater than the value reported in the device’s identify device data. A CompactFlash Storage Card implementation shall
support any legal host implementation.
2) This parameter specifies the time from the negation edge of -IORD to the time that the data bus is no longer driven by the
CompactFlash Storage Card (tri-state).
3) The delay from the activation of -IORD or -IOWR until the state of IORDY is first sampled. If IORDY is inactive then the host
shall wait until IORDY is active before the PIO cycle can be completed. If the CompactFlash Storage Card is not driving IORDY
negated at tA after the activation of -IORD or -IOWR, then t5 shall be met and tRD is not applicable. If the CompactFlash
Storage Card is driving IORDY negated at the time tA after the activation of -IORD or -IOWR, then tRD shall be met and t5 is
not applicable.
4) t7 and t8 apply only to modes 0, 1 and 2. For other modes, this signal is not valid.
5) IORDY is not supported in this mode.
