1.Description:
ATECC608 is the latest encryption authentication chip that uses I2C to send/receive commands. After using your detailed information to 'lock' the chip, you can use it for ECDH and AES-128 encryption/decryption/signature. There is also hardware support for random number generation and SHA-256/HMAC hash functions, which can greatly accelerate the encryption commands of slower microcontrollers.
This chip can be used in conjunction with 3.3V or 5V power/logic microprocessors, making it compatible a range of development boards.
