Alliance Memory 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.

The N25Q0x SPI NOR FLASH memory devices have 64x One-Time Programmable (OTP) bytes that can be read and programmed with the READ OTP and PROGRAM OTP commands. These 64x bytes can also be permanently locked with a PROGRAM OTP command. The devices can also pause and resume PROGRAM and ERASE cycles using dedicated PROGRAM/ERASE SUSPEND and RESUME instructions. The N25Q0x NOR FLASH memory devices can be operated with three protocols: extended SPI, dual I/O SPI, and quad I/O SPI.
