Integrated ISO/IEC 7816-3&4 UART interface
- Class A (5 V), class B (3 V), and class C (1.8 V) smart card supply
- Protection of smart card
- Three protected half-duplex bidirectional buffered I/O lines (C4, C7, and C8)
- Compliant with ISO/IEC 7816 and EMVCo standards
The PN7462 family offers the possibility to extend the number of contact interfaces available. It uses an I/O auxiliary interface to connect a slot extension (TDA8035 - 1 slot, TDA8020 - 2 slots, and TDA8026 - 5 slots)

- P2P active and passive, target and initiator
- Card emulation ISO14443 type A
- ISO/IEC 14443 type A and type B
- MIFARE products using Crypto1
- ISO/IEC 15693, and ISO/IEC 18000-3 mode 3
- Low-power card detection
- Dynamic Power Control (DPC)
- Adaptive Wave Control (AWC)
- Adaptive Range Control (ARC)
- Compliance with EMV contactless protocol specification
