3 Unique Function Descriptions
The following special features may be implemented to assist system manufactures in
making high quality, low cost USB storage systems.
ꢀ
The eKF5280 supports down-graded/untested NAND Flash. During testing of the
target NAND flash, if a flawed block is found, the controller will mark and isolate
this defective block. Consequently, the isolated block is excluded from operation
thereafter. The test software for this function is included in the supporting
programs provided with the controller.

To reduce cost and increase performance & reliability, the eKF5280 is equipped
with a built-in SRAM Look-Up-Table to support logical-to-physical address
translation.
The eKF5280 is also embedded with a built-in ECC function. The real time ECC
correction maintains the data integrity while preserving the high data transfer rate
at the same time.
A wear-level algorithm is implemented in the eKF5280 firmware to prevent oxide
degradation and subsequent failure from numerous repetitions of flash erase/
programming operation on the same block at high voltage. This algorithm
updates the data of a block into different new physical links to alleviate repetitive
cycling on the same block.
ꢀ
ꢀ
The eKF5280 is also equipped with a built-in 5 volt to 3.3 volt regulator. So there
is no need for an external regulator. Hence your BOM cost is reduced.
No additional driver is required for eKF5280 operation. It works readily with Win
XP, Win 2000, Win ME, and MAC OS 9.0 & higher (Win 98 is also supported after
installing a separate driver).
