Serial EEPROMS - I2C™

| Description |
Description
Traditional I2C Serial EEPROMs utilize hardware based write protection that only allows locking or unlocking the entire memory array via an external pin, which severely limits the possible ways to protect data. The 24CS Series devices address this limitation with the addition of a 16-bit Configuration register, which allows the write protection behavior to be configured for legacy hardware write protection or enhanced software write protection.
