ST X-NUCLEO-NFC08A1

The X-NUCLEO-NFC08A1 NFC 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 encoding and decoding in reader mode, suitable for standard applications such as NFC, close-coupling, and proximity HF RFID standards. It supports ISO/IEC14443 Type A and Type B, ISO/IEC15693 (single subcarrier only), and ISO/IEC18092 communication protocols, as well as detection, read, and write operations for NFC Forum Type 1, 2, 3, 4, and 5 tags. The on-board low-power capacitive sensor enables ultra-low-power wake-up without activating the reader field, with amplitude or phase measurement selectable via conventional inductive wake-up. Automatic Antenna Tuning (AAT) technology allows operation in the vicinity of metallic components and/or in changing environments.
