概览

CAT24C256 是一款 EEPROM 串行 256-Kb I2C，内部组织为 512 页，每页 64 字节。它具有 64 字节页写入缓存，支持标准 (100 kHz)、快速 (400 kHz) 和超快 (1 MHz) I2C 协议。写入操作可通过将 WP 引脚置于高电平类禁止（这样会保护整个内存）。外部地址引脚使其能够在同一个总线上放置最多八个 CAT24C256 器件。片上 ECC（错误修正代码）使得该器件适用于高可靠性应用。

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.)
