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).
11 Propagation delay is with 10 mV overdrive.
