CompactFlashTM Card
FEATURES
DESCRIPTION
ꢀ
Fully compatible with PC Card Standard &
The WEDC CompactFlash™ Card consists of a
CompactFlash™ Controller, which supports Toshiba/
Samsung NAND type flash. The CompactFlash™
Card meets CFA specification V1.4, and provides error
correcting code (ECC) reliability to detect and correct
errors automatically.
CFA(Compact Flash Association) Standard.
Support 3 variations of mode access
• I/O Card Mode
ꢀ
• Memory Card Mode
• True- IDE Mode
* This product is subject to change without notice.
ꢀ
ꢀ
+5.5V / +3.0V single power supply.
Internal Error Correction Logic
• Data Interleave to 2 for each 256 Bytes.
Notes: CompactFlash™ is a trademark of SanDisk Corporation and is licensed royalty-
free to the CFA, which in turn will license it royalty-free to CFA members.
CFA: CompactFlash™ Association.
• Error Correction of 1 Byte random error per 128
Bytes of data.
• Automatic on-the-fly, in-buffer error correction.
ꢀ
ꢀ
Compatible with all PC Card Service and Socket
Service.
Integrated PC Card attribute memory of 256
Bytes(CIS).
ꢀ
ꢀ
ꢀ
4 PC Card function register support.
Support Host-side Write Protect.
Automatic wake up from power-down on host reset
or command write.
ꢀ
ꢀ
Sector data transfers without microprocessor
intervention.

Notes :
1. These signals are required only for 16 bit access and not required when installed in 8 bit systems. Devices should allow for 3-state signals not to consume current.
2. Should be grounded by the host.
3. Should be tied to VCC by the host.
4. Optional for CE + Cards, Required for CompactFlash Storage Cards.
