ATECC608A-MAHDA-T Integrated Circuit Chip with 72 bit Data Bus Width for Secure Authentication in IoT Market

ATECC608 integrates ECDH (Elliptic Curve Diffie Hellman) security protocol - an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication for the Internet of Things (IoT) market. Applications include home automation, industrial networking, medical systems, as well as accessories and consumables authentication. The ATECC608 also offers an integrated AES hardware accelerator, strengthening hardware-based security for LoRaWAN applications and enabling secure boot capabilities for very small microcontrollers.
