EEPROM Memory | NV25640
概览
NV25640 是一款 EEPROM 串行 64-Kb SPI - 汽车级 0 (+150°C) 器件，内部组织为 8kx8 位。它具有 32 字节写入缓冲区，支持串行外围接口 (SPI) 协议。该器件通过芯片 (CS) 输入启用。另外，必备总线信号为时钟输入 (SCK)、数据输入 (SI) 和数据输出 (SO) 线。HOLD 输入可用于暂停与 NV25xxx 器件的任何串行通信。该器件具有软硬件写保护功能，包括部分保护和全阵列保护。字节级片上 ECC（错误修正代码）使得该器件适用于高可靠性应用。该器件提供了一个附加标识页，可以对其进行永久性写保护。
