General Description SPECIFICATION The eKF5250 provides a high-performance interface to bridge USB and NAND Flash compliance device which can be used to implement of flash memory storage device with USB interface. It contains a 8-bit RISC processor to greatly reduce firmware development work. 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.
