8.5.2 Supported Features
• 32-bit data path
• Support for x8 devices
• Both SLC (Single Level Cell) and MLC (Multi Level Cell) NAND flash support
• Support for NAND boot
• Support for 2048 and 4096 byte page sizes
• Up to one bank (device)
• BCH ECC with eight bit error correction
• Multiplane device support
• Support for devices from multiple vendors (Samsung, Toshiba, Micron, Hynix)

* Note: Intel only tested and validated NAND devices up to 32 Gb. The NAND controller
inside the silicon might be able to support up to 128 Gb. If the designer prefers to choose a
NAND part beyond 32 Gb, please check with your local FAE (Field Application Engineer) for
advice.
