The CompactFlash is a small form factor non-volatile memory card which provides high
capacity data storage. Its aim is to capture, retain and transport data, audio and images,
facilitating the transfer of all types of digital information between a large variety of digital
systems.
The Card operates in three basic modes:
●
●
●
The CompactFlash also supports Advanced Timing modes. Advanced Timing modes are
PCMCIA style I/O modes that are 100ns or faster, PCMCIA Memory modes that are 100ns
or faster, True IDE PIO Modes 5,6 and Multi-Word DMA Modes 3,4.
It conforms to the PC Card Specification when operating in the PCMCIA I/O mode, and in
the PCMCIA Memory mode (Personal Computer Memory Card International Association
standard, JEIDA in Japan), and to the ATA specification when operating in True IDE Mode.
CompactFlash Cards can be used with passive adapters in a PC-Card Type II or Type III
socket.
The Card has an internal intelligent controller which manages interface protocols, data
storage and retrieval as well as hardware RS-code Error Correction Code (ECC), defect
handling, diagnostics and clock control. Once the Card has been configured by the host, it
behaves as a standard ATA (IDE) disk drive. The hardware RS-code ECC allows to detect
and correct 4 Bytes per 528 Bytes.
The Card has a super Cap on V
prevent data corruption after power-down.
The specification has been realized and approved by the CompactFlash Association (CFA).
This non-proprietary specification enables users to develop CF products that function
correctly and are compatible with future CF design.
