CAT25256 是一款 EEPROM 串行 256-Kb SPI 器件,内部组织为 32kx8 位。它具有 64 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 CAT25256 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。可用于新产品(修订版E)。

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
