3.3V operation
The W7NCF-H-M1 series CompactFlash® family is
designed for high reliability and robust operation. This
product not only offers a strictly controlled and locked bill
of materials but also the robust operation which is desired
in many medical applications. The product’s reliability
backbone is established by using a 32 bit RISC based
controller along with the best SLC (single level cell) NAND
flash memory devices. Utilizing proprietary techniques, our
card offers both firmware and hardware features which
mitigate problems relating to power disturbances and
interruptions. Implemented is the industry leading ECC
protection which is capable of correcting 6 bytes in every
512 byte sector. This leading ECC protection combined
with patented static wear leveling technology provides the
highest read/write endurance possible.
