The WED7PxxxCFA70xxI25 series CompactFlash™ card
is an ATA interface flash memory card based on flash
technology. The CompactFlash™ card is constructed with
a flash disk controller chip and NAND-type flash memory
device. Operates from a single 5-Volt or 3.3-Volt power
source. The card is available in CompactFlash™ type-I
form factor with 128MB, 256MB, 512MB and 1.02GB
unformatted capacity. Being able to emulate IDE hard disk
drives and certified in accordance with the CompactFlash™
Certification Plan, WEDC’s CompactFlash™ card is a

Notes: 1. These signals are required only for 16 bit access and not required when installed in 8 bit systems. Devices allow for 3-state signals to consume no current.
2. Should be grounded by the host.
3. Should be tied to VCC by the host.
ACCESS SPECIFICATIONS
1. Attribute access specifications
When CIS-ROM region or Configuration register region is accessed, read and write operations are executed under the
condition of REG# = ”L” as follows. That region can be accessed by Byte/Word/Odd-byte modes, which are defined by
PC card standard specifications.

3. TRUE IDE MODE
The card can be configured in a True IDE. This card is configured in this mode only when the OE# input signal is asserted
to GND by the host during power on . In this True IDE mode Attribute Registers are not accessible from the host. Only
I/O operation to the task file and data register is allowed. If this card is configured during power on sequence, data
register is accessed in word (16-bit). The card permits 8-bit accesses if the user issues a Set Feature Command to put
the device in 8-bit mode.

ATTENTION FOR CARD USE
•
•
In the reset or power off mode, the information in all registers are cleared.
Note that the card insertion/removal should not be executed while host is active if the card is used in True IDE
mode.
•
•
•
•
After the hard reset, soft reset or power-on reset or ATA reset command is applied the card cannot be accessed
while READY pin is “low.” Flash card can’t be operated in this mode.
Before insertion VCC cannot be supplied to the card. After confirmation that CD1#, CD2# pins are set, VCC may
be supplied to the card.
OE# must be kept at the VCC level during power on reset in memory card mode and I/O card mode. OE must be
kept constantly at the GND level in True IDE mode.
Do not turn off the power or remove WED7PxxxCFA70xxI25 Series from the slot before read/write operation is
complete. Avoid using WED7PxxxCFA70xxI25 Series when the battery is low. Power shortage, power failure
and/or removal of WED7PxxxCFA70xxI25 Series from the slot before read/write operation is complete may
cause malfunction of WED7PxxxCFA70xxI25 Series, data loss and/or damage to data.
•
Routine performance of backing-up data (or taking back-up of data) is strongly recommended.
