The ECC204 is a member of the CryptoAuthentication™ product family. The device is targeted for disposable and ecosystem control applications and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers. Consider implementing an ATECC608 in your host to perform the ECDSA P256 verify function of the signature your disposable or accessory would return. You could leverage that same ATECC608 for mutual authentication to an IoT cloud platform
For Qi 1.3 and Qi 2.0 wireless charging in consumer applications, refer to the ECC204 TrustFLEX WPC
For Qi 1.3 and Qi 2.0 wireless charging in Automotive applications, refer to the TA010.

| The CryptoAuth Trust Platform provides a compact development solution for developing IoT solutions with the ATECC608B-TNGTLS and ATECC608B-TFLXTLS and ATECC608B-MAHDA devices or the ATECC608C equivalents.
|
| The AT88CKSCKTUDFN-XPRO is an XPRO extension board that attaches 8-pin UDFN CryptoAuthentication™ devices to Microchip MCU's that support an XPRO interface. All Microchip CryptoAuthentication™ devices regardless of interface can be used with this board.
|
| The EV92R58A Development board is a mikroBUS accessory board for evaluating the ECC204. The board can readily be used with a Microchip DM320118 Trust platform host board or any MicroController board that supports a mikroBus Interface. It is recommended that this board be used with the Microchip CryptoAuthentication Library (CAL) .
|
| The EV27Y72A is a 3-Lead Contact Socket Board used to support applications using the 3-Lead Contact Package. in either a powered or parasitic power mode. The socket can be used with the following devices ATECC608B, ATSHA204A, ECC204, SHA104 and TA010.
|
| The MikroElektronica Secure SOIC click board is an 8-pin SOIC socket board that works with Microchip Security Products and the TrustPlatform Development Board
