ATECC608A-TNGTLS CryptoAuthentication™ Data Sheet
■The ATECC608A-TNGTLS is a preprovisioned variant of the ATECC608A. The Trust&GO secure element is part of Microchip’s family of generically provisioned security-focused devices. The device configuration was designed to make the secure element applicable to some of the most common use cases in the IoT market, while minimizing the learning and start-up curves associated with security devices.
■This data sheet provides the slot and key configuration information that is unique to the ATECC608A-TNGTLS. This information clearly defines the access policies of each of the data zone slots. Only relevant command and I/O operating information has been included. An application section discussing Microchip’s hardware and software tools that can aid in developing an application is also provided with additional links to the location of the tools.
●Features:
■Fully Specified Configuration Zone
■I²C Interface with One-Time Changeable I²C Address
■One Permanent Primary P-256 Elliptic Curve Cryptography (ECC secp256r1) Private Key Fixed at Manufacturing Time
■One Internal Sign Private Key for Key Attestation
■Three Secondary P-256 ECC Private Keys that Can Be Regenerated by the User
■Signer Public Key from Signer Certificate
■IO Protection Key Slot to Protect I²C Communication
■ECDH/KDF Key Slot Capable of Being Used with AES Keys and Commands
■X.509 Compressed Certificate Storage
■Available in 8-Pad UDFN and 8-Pin SOIC Packages in 2k or 100 unit production quantities.
