The EP501 NAND Flash controller provides an easy interface for user to access NAND Flash devices. NAND Flash devices, with its unique protocol of command, address, data cycles and ECC requirements, requires extra design effort and this IP core solves this problem and makes NAND Flash devices user-friendly again. The EP501 NAND Flash controller supports BCH code for multi-bit error correction with option for hamming code single-bit error correction. Up to 60-bit ECC capability can be provided. Multiple NAND Flash devices can be cascaded to provide large memory space while the 16-bit data width option double the data bandwidth. Multi-channel design can also be realized with multiple core instantiation. While ONFI compliant, the EP501 also includes many features to improve system performances such as DMA, boot ROM support, write-trigger-read and a large choice of CPU bus interface options.
