SPI (Serial Peripheral Interface) NAND Flash provides a small size and low pin count solution in high density non-volatile memory storage solution for embedded systems.

The SPI NAND Flash follows the industry-standard serial peripheral interface. It is an attractive alternative to SPI-NOR and standard parallel NAND Flash. The total pin count is 8, including VCC and GND.
