Functional overview

STM32G483xE

34/230

DS12997 Rev 3

The AES peripheral supports:

•

Encryption/decryption using AES Rijndael block cipher algorithm

•

NIST FIPS 197 compliant implementation of AES encryption/decryption algorithm

•

128-bit and 256-bit register for storing the encryption, decryption or derivation key (4x

32-bit registers)

•

Electronic codebook (ECB), cipher block chaining (CBC), Counter mode (CTR), Galois

Counter Mode (GCM), Galois Message Authentication Code mode (GMAC) and Cipher

Message Authentication Code mode (CMAC) supported

•

Key scheduler

•

Key derivation for decryption

•

128-bit data block processing

•

128-bit, 256-bit key length

•

1x32-bit INPUT buffer and 1x32-bit OUTPUT buffer

•

One 128-bit Register for the initialization vector when AES is configured in CBC mode

or for the 32-bit counter initialization when CTR mode is selected, GCM mode or

CMAC mode

•

Automatic data flow control with support of direct memory access (DMA) using 2

channels, one for incoming data, and one for outcoming data

•

Suspend a message if another message with a higher priority needs to be processed.

Timers and watchdogs

The STM32G483xE devices include three advanced motor control timers, up to nine

general-purpose timers, two basic timers, one low-power timer, two watchdog timers and a

SysTick timer. The table below compares the features of the advanced motor control,

general purpose and basic timers.
