INDUSTRIAL GRADE CompactFlashTM Card
W7CFxxxA-H4 Series RoHS 6/6 Compliant
256MB – 32GB
DESCRIPTION
Wintec’s Compact Flash card is based on industrial leading Hyperstone F4 controller chip, which is a 32-bit RISC
processor with instruction set extension optimized for Flash handling. The superior wear leveling done by the
controller chip involves all physical blocks including the ones containing static data to meet the most demanding
requirements from users in a data traffic intensive environment.
The card contains a 50-pin connector consisting of two rows of 25 female contacts each on 50 mils (1.27mm)
centers. The Industrial Grade CompactFlashTM Memory Cards are constructed with Samsung or Micron single-level-
cell (SLC) NAND flash memory devices. It employs a variety of sophisticated functions, such as the Reed-Solomon
error correction code which is capable of correcting up to 4 symbols in a 512 bytes sector with additional CRC for
dynamic error checking. The wear-leveling methods ensure even wear of flash blocks across the entire card
capacity. With background operations to track erase counts, the card prioritizes new writes to blocks with lower
wear, and relocates static data to blocks with higher wear. Bad-block Management routines replace worn blocks
with spare blocks reserved by the controller on card initialization. All Flash management utilities allow for
maximum levels of data reliability and card endurance for prolong life cycle.
