Working Principles

The AT88SC12816C-MJ utilizes a combination of hardware-based encryption, authentication protocols, and tamper detection mechanisms to provide secure memory storage. When data is written to the chip, it undergoes encryption using the built-in encryption algorithms. The encrypted data is then stored in the non-volatile memory cells. During read operations, the data is decrypted and made available to the host device through the serial interface.

To ensure the integrity and authenticity of the stored data, the chip supports various authentication protocols. These protocols verify the validity of the data and protect against unauthorized modifications or tampering. In case of any tampering attempts, the tamper detection mechanisms trigger appropriate actions, such as erasing the stored data or generating an alert signal.
