MAC Address
The SST26VF064BEUI is pre-programmed at the factory with globally unique EUI-48 and EUI-64 node identifiers.
The addresses are located in the Serial Flash Discoverable Parameters (SFDP) table and accessible via the SFDP
read instruction.
The 6-byte EUI-48 address value of the SST26VF064BEUI is stored in the SFDP table at address locations 0x261
through 0x266.
The 8-byte EUI-64 address value of the SST26VF064BEUI is stored in the SFDP table at address locations 0x268
through 0x26F.

Secure Element
The Microchip ATECC608B-TNGTLS is the Trust&GO secure element part of the Trust Platform for the
CryptoAuthentication family. The device comes pre-configured and pre-provisioned with default thumbprint
certificates and key. The cloud infrastructure, whether it is a public or private network, must accommodate device
authentication relying only on the thumbprint certificate from the ATECC608B-TNGTLS. This secure element
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, including home automation, industrial networking, medical, retail or any TLS
connected networks.
