6.6 ECB — AES electronic codebook mode encryption

The AES electronic codebook mode encryption (ECB) can be used for a range of cryptographic functions

like hash generation, digital signatures, and keystream generation for data encryption/decryption. The ECB

encryption block supports 128 bit AES encryption (encryption only, not decryption).

a Propagation delay is with 10 mV overdrive.
