Introduction

The ATECC608C-TFLXTLS is a pre-provisioned variant of the ATECC608C. The ATECC608C provides enhanced security measures over that of the ATECC608A and ATECC608B. These enhancements also apply to the ATECC608C-TFLXTLS. 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 ATECC608C-TFLXTLS configuration is similar to that of the ATECC608C-TNGTLS. Some additional flexibility and capability 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 ATECC608C-TFLXTLS devices. A Single Wire Interface (SWI) option is also available for this device.

This data sheet provides the slot and key configuration information that is unique to the ATECC608C-TFLXTLS. This information clearly defines the access policies of each of the data zone slots. Limited command and I/O operating information has been provided since the devices are to be used with the Trust Platform Development Suite (TPDS) tools. 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.
