6 Application Information

The ATECC608A-TNGLoRaWAN is a member of the Microchip’s Trust&GO CryptoAuthentication family of products. The Trust&GO products are easy to use, simple to implement and allow even low volume customers to implement security into their end system while leveraging Microchip’s expertise and infrastructure in secure provisioning.

The ATECC608A-TNGLoRaWAN device is compatible with the LoRaWAN 1.1 specification and backwards compatible with the LoRaWAN 1.0 specification. Primary enhancement to LoRaWAN 1.1 was associated with improving overall security. Support for LoRaWAN Backend Interfaces has been built into the device to offer support for roaming access across various LoRaWAN networks.

The ATECC608A-TNGLoRaWAN device has been developed to take the guesswork out of adding security to a LoRa Wide Area Network. The product has been preconfigured to readily connect IoT devices to major LoRa network service providers such as Actility and TTI. For any given application, a specific network infrastructure provider must be selected. Each infrastructure provider will have its own private key from which diversified parent keys for each device are generated. The diversified parent keys are then used to generate multiple network and application AES Session keys.

The ATECC608A-TNGLoRaWAN device is integrated with the Microchip’s Secure Provisioning environment to quickly and easily add devices to major network security providers. This allows for rapid prototyping to verify new designs and rapid deployment of products once initial prototyping is complete.
