The ECC608-TFLXWPC is the TrustFLEX pre-provisioned secure element part of the Microchip’s Trust Platform offering. The device configuration was designed to meet the secure authentication requirements mandated by the Wireless Power Consortium (WPC) Qi® 1.3 version of the standard. The ECC608-TFLXWPC configuration is defined to meet the basic authentication needs of Qi chargers that provide authentication. If so desired, dual WPC certificate slots can also be implemented. In addition, extra use cases were implemented for users who want to provide TLS authentication from the embedded system where the charger is or to provide secure boot capabilities. While some data slots are required for specific use, others provide flexibility to be used for other applications. These slot access policies will be set by the Trust Platform Design Suite tools prior to ordering the ECC608-TFLXWPC devices. This data sheet provides the slot and key configuration information that is unique to the ECC608-TFLXWPC. This information defines the access policies of each of the data zone slots. Only relevant command and I/O operating information is 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. 

The ATECC608 offer many use cases in addition to the Qi 1.3 authentication. If Qi 1.3 is the only use case desired:

• Qi 1.3 wireless charging in consumer applications, refer to the ECC204 TrustFLEX WPC
• Qi 1.3 wireless charging in Automotive applications, refer to the TA010.
