The ATECC608B-TFLXTLS 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-TFLXTLS. The TrustFLEX secure element is part

of Microchip’s family of generically provisioned security-focused devices. The device conguraon 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 ATECC608B-TFLXTLS conguraon idencal is nearly to that of the ATECC608B-TNGTLS. Some has beenaddional exibility

provided with respect to data loaded into cercate and key slots and the locking of those slots. These slot accessopons

polices will be set by the Trust Design Suite tools prior to ordering the ATECC608B-TFLXTLS devices. A Single WirePlaorm

Interface (SWI) is also available for this device.opon
