Notes:
 To configure the card for removable, fixed disk, etc., replace the xx in the partnumbers above as follows: FD: Fixed Disk, DMA/UDMA Enabled F1: Fixed Disk, DMA/UDMA Disabled
 F2: Fixed Disk, DMA Enabled, UDMA Disabled XX: Removable Disk, DMA/UDMA Enabled X1: Removable Disk, DMA/UDMA Disabled X2: Removable Disk, DMA Enabled, UDMA Disabled X3: Removable Disk, DMA Enabled, UDMA Restricted to UDMA 2
 To add Conformal Coating, change the 000 in the part number to 050.
 To add full mechanical ruggedization (which may include underfill / epoxy on
component leads, conformal coating and silicone sealant between main
components and case) change the CE in the part number to CR.
 Usable capacities are within 10% of the gross capacity figures shown above,
which is typical with all NAND flash devices, as a small portion of the total isneeded for controller firmware and spare block reserves.

Description
The signal is RDY/-BSY pin.
RDY/-BSY pin turns low level
during the card internal
initialization operation at Vcc
applied or reset applied, so next
access to the card should be after
the signal turned high level.
This signal is active low -IREQ pin.
The signal of low level indicatesthat the card is requesting
software service to host, and highlevel indicates that the card is not
requesting.
This signal is the active highInterrupt Request to the host.
-REG is used during memory
cycles to distinguish between task
file and attribute memory
accesses. Attribute memory selectHigh for task file, Low for attributememory is accessed.
-REG is constantly low when task
file or attribute memory isaccessed.
This is a DMA Acknowledge signalby the host in response to DMARQ
to initiate DMA transfers.
This signal is active high RESET
pin. If this signal is asserted high,the card internal initialization
begins to operate. During the card
internal initialization RDY/-BSY islow. After the card internal
initialization RDY/-BSY is high.
This signal is active high RESET
pin. If this signal is asserted high,the card internal initialization
begins to operate. In this mode,
RDY/-BSY signal cannot be used,
so using Status Register the
Ready/Busy status can be
confirmed.

4.7 Interface/Bus Timing
There are two types of bus cycles and timing sequences that occur in the PCMCIA type interface,a direct mapped I/O transfer and a memory access. The two timing sequences are explained indetail in the PCMICA PC Card Standard. Delkin’s CompactFlash Card conforms to the timing inthat reference document.

4.8 CF-ATA Command Description
This section defines the software requirements and the format of the commands the host sends
to the CompactFlash cards. Commands are issued to the CompactFlash card by loading therequired registers in the command block with the supplied parameters, and then writing thecommand code to the Command register. The manner in which a command is accepted varies.
These are three classes of command acceptance, all dependent on the host not issuingcommands unless the CompactFlash card is not busy (BSY=0).

5.0 Comparing CF-ATA to PC Card-ATA and True IDE
This section details the differences between CF-ATA when compared to the PC Card-ATA andTrue IDE.

5.1 Electrical Differences
5.1.1 TTL Compatibility
CF is not TTL compatible, it is a purely CMOS interface. Refer to Electrical Specification
section covered earlier in this document.
5.1.2 Pull Up Resistor Input Leakage Current
The minimum pull up input leakage current is 50K ohms rather than the 10K ohms stated in
the PCMCIA specification.

5.2 Functional Differences
5.2.1 Additional Set Features Codes in CF-ATA
The following Set Features codes provide additional functionality in CF-ATA, but are notstandard in PC Card-ATA or True IDE:
1. 69H, Accepted for backward compatibility
2. 96H, Accepted for backward compatibility
3. 97H, Accepted for backward compatibility
4. 9AH, Set the host current source capability
5.2.2 Additional Commands in CF-ATA
The following commands provide additional functionality in CF-ATA, but are not standard
PC Card-ATA commands.
PC Card-ATA and True IDE define the following command codes as vendor unique:
1. C0H, Erase Sectors
2. 87H, Translate Sector
3. F5H, Wear Level
PC Card-ATA and True IDE define the following command codes as reserved:
1. 03H, Request Sense
2. 38H, Write Without Erase
3. CDH, Write Multiple Without Erase
5.2.3 Idle Timer
The CF-ATA Idle timer uses an increment value of 5 ms, rather than the 5 second minimum
increment value specified in PC Card-ATA/True IDE.

5.2.4 Recovery from Sleep Mode
For CF devices, recovery from sleep mode is accomplished by issuing another command to
the device. A hardware or software reset is not required.

Notes:

1. F = content (byte) is fixed and does not change
2. V = content (byte) is variable and may change depending on the state of the device or the commands
executed by the device
3. X = content (byte) is vendor specific and may be fixed or variable
4. R = content (byte) is reserved and shall be zero.
