MR25H40 semiconductor 系列
Everspin Technologies, Inc.3.3V 4Mb SPI NVRAM MRAM芯片，紧凑型8引脚DFN封装
Everspin Technologies的MR25H40系列是一款采用磁阻随机存取存储器（MRAM）技术的3.3V、4MB串行外设接口（SPI）非易失性随机存取存储器（NVRAM）设备。这些芯片采用小型8引脚DFN封装，适用于空间受限的应用。如果您正在开发需要高速、非易失性存储且功耗低、写入速度快的项目，这些MRAM芯片非常适合。值得一提的是它们出色的耐久性——MRAM可以在不降级的情况下承受数百万次写入周期，这在磨损平衡场景中比传统闪存具有明显优势。另一个实用的好处是即使在没有电源的情况下也能保持数据，使其非常适合电池供电的设备或在断电期间需要保证数据完整性的系统。
