The Microchip ATECC608A-MAHCZ-T is a hardware secure element that adds cryptographic authentication and secure key storage to IoT devices. It offloads ECDSA/ECDH, AES-128, and SHA-256 operations from the host MCU, enabling secure boot, device identity, and encrypted LoRaWAN/cloud provisioning without exposing keys in firmware.
