ST25R3915 - Automotive high performance reader / NFC initiator

Download the ST25R3915 datasheet PDF. This datasheet also covers the ST25R3914 variant, as both devices belong to the same automotive high performance reader / nfc initiator family and are provided as variant models within a single manufacturer datasheet.

Description

The ST25R3914/5 are highly integrated NFC initiators / HF reader ICs for automotive applications, AEC-Q100 grade 1 qualified, including the analog front end (AFE) and a highly integrated data framing system for ISO 18092 (NFCIP-1) initiator, ISO 18092 (NFCIP-1) active target, ISO 14443A and B reader

Features

  • AEC-Q100 qualified.
  • ISO 18092 (NFCIP-1) Active P2P.
  • ISO14443A, ISO14443B, ISO15693 and FeliCa™.
  • Support HBR up to 848 kbit/s PICC to PCD and PCD to PICC framing.
  • Capacitive sensing - Wake-up.
  • Automatic antenna tuning system providing tuning of antenna LC tank (ST25R3914 only).
  • Automatic modulation index adjustment.
  • AM and PM demodulator channels with automatic selection.
  • Up to 1 W in case of differential output.
