•
Protection of smart card
•
Three protected half-duplex bidirectional buffered I/O lines (C4, C7, and C8)
•
Compliant with ISO/IEC 7816 and EMVCo 4.3 standards
1.2.3 Integrated contactless interface front end
•
High RF output power frontend IC for transfer speeds up to 848 kbit/s
•
NFC IP1 and NPFC IP2 support
•
Full NFC Tag support (Type 1, Type 2, Type 3, Type 4 A and B)
•
P2P active and passive, target and initiator
•
Card emulation ISO14443 type A
