The ATECC608A-TFLXTLS is a pre-provisioned variant of the ATECC608A. The TrustFLEX 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.
The ATECC608A-TFLXTLS configuration is nearly identical to that of the ATECC608A-TNGTLS. Some additional flexibility has been provided with respect to data loaded into certificate and key slots and the locking options of those slots. These slot access polices will be set by the Trust Platform Design Suite tools prior to ordering the ATECC608A-TFLXTLS devices. A Single Wire Interface (SWI) option is also available for the ATECC608A-TFLXTLS device.
This data sheet provides the slot and key configuration information that is unique to the ATECC608A-TFLXTLS. 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.
