ST25R3916B: New NFC reader accelerates payment, consumer and industrial application designs


The ST25R3916B is a high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes when applicable.

It can be used in contactless payment, device-pairing, wireless-charging, brand protection, and other industrial and consumer applications.

Fully compliant with EMVCo 3.1a analog and digital, this NFC IC is optimized for POS terminal applications, and enables fast EMVCo certification cycles, even under harsh conditions (e.g., antenna placed near noisy LCD displays).

Key features

  • Operating modes
    • Reader/writer
    • Card emulation
    • Active and passive peer to peer
  • Key features
    • Dynamic power output (DPO) controls the field strength to stay within given limits
    • Active wave shaping (AWS) reduces over-and under-shoots and eases certification after EMVCo and NFC Forum
    • Noise suppression receiver (NSR) allows reception in noisy environment
    • Automatic antenna tuning (AAT) via variable capacitor
    • Integrated EMVCo® 3.1a compliant EMD handling
