EdgeLockSE050 with NFC Controller

[julian_sauer]

1) does NXP offer a solution where a EdgeLockSE050 with a NFC Controller can communicate p2p with a Smartphone via NFC (the EdgeLock will receive the power from the Smartphone via NFC Harvesting)?

2) if no is there a solution with a Secure Element + NFC Controller from NXP

Thank you very much

best wishes

Hi Julian,

The SE050 in Variant C also has the contactless interface enabled. This is a ISO14443-A PICC interface, so the secure element looks like a card to any NFC-enabled smartphone.

NFC phones can send custom APDUs using the ISO14443-4 exchange/transcieve functions of the OS to the SE050. These command APDU will be processed by the SE050 in the same way as if they were sent over I2C.

Just keep in mind that SE050 can use one interface at one time. The interface which got selected on IC boot up is the only one which you can use for communication. So to communicate over ISO14443 the I2C interface needs to be off.

Have a great day,
Kan
