N25Q0x SPI NOR FLASH Memory Devices Alliance Memory N25Q0x SPI NOR FLASH Memory Devices are high-performance multiple input/output serial Flash memories manufactured on 65nm NOR technology. These memory devices feature execute-in-place (XIP) functionality, a high-speed SPI-compatible bus interface, and advanced write protection mechanisms. The N25Q0x NOR FLASH memory devices can double or quadruple the transfer bandwidth for READ and PROGRAM operations. This is made possible by the innovative, high-performance, dual/quad input/output instructions. Software can write-protect these memory devices through volatile and nonvolatile protection features, depending on the application's needs. The protection granularity is 64KB (sector granularity) for volatile protections.
