In summary, the main features of  the Microchip SAM9G46 and SAM9M11 hardware encryption peripherals are the Advanced Encryption Standard (AES), the Data Encryption Standard (DES) and the Triple Data Encryption Standard (TDES). The NIST publication SP800-38 defines the five most commonly used operating modes as Electronic Code Book, Cipher Block Chaining, Output FeedBack, Cipher FeedBack and Counter mode. The Microchip SAM9G46 and SAM9M11 fully support these cryptographic algorithms in the range of operation modes as defined by the NIST.
