DESCRIPTION
The Wintec Industries W7CFxxxA-H series of ROHS Compliant Industrial Grade CompactFlash
TM
Memory Cards are
constructed with Samsung NAND-type single-level-cell (SLC) flash memory devices paired to a powerful 32-bit RISC/DSP-
based system controller for virtual-to-physical address mapping and other flash management functions.
Wintec Industrial CompactFlash
TM
Cards employ a variety of sophisticated error checking and flash management utilities
allowing for maximum levels of data reliability and card endurance. Patented wear-leveling methods ensure even wear of flash
blocks across the entire card capacity. Background operations track erase counts, prioritize new writes to blocks with lower
wear, and relocate static data to blocks with higher wear. Bad-block Management routines replace worn blocks with spare blocks
reserved by the controller on card initialization. Reed-Solomon based ECC algorithms capable of detecting and correcting up to
6 bytes per 512 byte sector are implemented on the fly without performance degradation to ensure data reliability through user
data transfers and background wear-leveling operations. Additional information regarding the specifics of wear leveling, ECC
methods, and application-specific card life calculations are available upon request and under NDA.
Industrial grade reliability, industry standard compatibility, and the ability to emulate IDE hard disk drives make Wintec
CompactFlash
TM
Cards ideal for industrial, military, and other high endurance applications.
