26.2 Overview
The Advanced Encryption Standard (AES) is a commonly used standards for cryptography. It is supported through an
AES peripheral module, and the communication interfaces and the CPU can use these for fast, encrypted
communication and secure data storage.
The AES crypto module encrypts and decrypts 128-bit data blocks with the use of a 128-bit key. The key and data must
be loaded into the key and state memory in the module before encryption/decryption is started. It takes 375 peripheral
clock cycles before the encryption/decryption is done. The encrypted/encrypted data can then be read out, and an
optional interrupt can be generated. The AES crypto module also has DMA support with transfer triggers when
encryption/decryption is done and optional auto-start of encryption/decryption when the state memory is fully loaded.
