GENERAL DESCRIPTION
The serial electrical interface follows the industry-standard serial peripheral interface (SPI), providing a cost-effective non-volatile memory storage solution in systems where pin count must be kept to a minimum. The device is a 512Mb SLC SPI-NAND Flash memory device based on the standard parallel NAND Flash, but new command protocols and registers are defined for SPI operation. It is also an alternative to SPI-NOR, offering superior write performance and cost per bit over SPI-NOR.
