EEPROM 串行 2-Mb SPI,低功耗

Active

概览

EA2M 是一款 EEPROM 串行 2-Mb SPI 低功耗器件,内部组织为 256Kx8 位。它具有 256 字节页写入缓存,支持串行外围接口 (SPI) 协议。该器件通过芯片选择 (CS) 输入启用。另外,所需总线信号为时钟输入 (SCK)、数据输入 (SI) 和数据输出 (SO) 线路。保持输入可用于暂停与 EA2M 器件的任何串行通信。该器件具有软件和硬件写保护,包括部分和完整阵列保护。片上 ECC(错误修正代码)使得该器件适用于高可靠性应用。 该 EA2M 器件具有超低功耗,适用于实时数据记录应用、助听器和其他医疗设备和电池供电应用。
