GENERAL DESCRIPTION
SPECIFICATION The eKF5250 has a phase Lock Loop(PLL) embedded. The PLL provided all clocks needed in this Controller. It needs an externally provided clock operating in 2 Mhz. The eKF5250 can control up to 4 pieces of NAND Flash memory. The flash capacity can be 16M bytes up to 256M bytes. And these chips can be any combination. It has been optimized to support Toshiba and Samsung flash memory designs. The controller has write-protected ability to prevent writing data to flash. For read/write operation, the controller can achieve 1000KB /800KB throughput. This controller can operate in Win XP, Win2000, Windows ME without any driver installation. 2.FEATURES
