ATECC608B-TNGTLS CryptoAuthentication Data Sheet

Introduction

The ATECC608B-TNGTLS is a pre-provisioned variant of the ATECC608B. The ATECC608B provides enhanced

security measures over that of the ATECC608A. These enhancements also apply to the ATECC608B-TNGTLS.

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 ATECC608B-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.
