DESCRIPTION

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

perfect choice for solid-state mass-storage in industrial

applications and applications that require performance and

extended environmental tolerances. Other applications

include handheld devices such as Digital Cameras, Audio

Players, and PDAs.
