The X-NUCLEO-NFC08A1 NFC card reader expansion board is based on the ST25R3916B device. The expansion board is configured to support ISO14443A/B, ISO15693, FeliCa™, and AP2P communication. The ST25R3916B manages frame coding and decoding in reader mode for standard applications, such as NFC, proximity, and vicinity HF RFID standards. It supports ISO/IEC 14443 type A and B, ISO/IEC 15693 (single subcarrier only) and ISO/IEC 18092 communication protocols as well as the detection, reading and writing of NFC forum type 1, 2, 3, 4, and 5 tags. The on-board low-power capacitive sensor performs ultra-low power wake-up without switching the reader field on and traditional inductive wake-up to select amplitude or phase measurement. The automatic antenna tuning (AAT) technology enables operation close to metallic parts and/or in changing environments.
