2. What are the differences between PN7150 and PN7150X?
PN7150X copies exact same characteristics than PN7150 (package, pinning, power
supply, interface, command set …). It only adds, on top of existing PN7150
functionalities, support for Apple Enhanced Contactless Polling.
Current version of PN7150X allows inserting the VASUP-A command to the discovery
loop, between usual Type A and Type B polling phases. It doesn’t care of any response
but then continue with the next enabled phase.
