Both the CR95HF and ST25R95 devices manage frame coding and decoding in Reader mode for standard applications, such as NFC, proximity and vicinity standards. They embed an analog front end to provide the 13.56 MHz air interface. These ICs support ISO/IEC 14443 Type A and B, ISO/IEC 15693 (single or double subcarrier) and ISO/IEC 18092 communication protocols, besides being MIFARE Classic (a) compatible . They also support the detection, reading and writing of NFC Forum Type 1, 2, 3 and 4 tags. The CR95HF / ST25R95 feature an optimized power management scheme, including tag detection mode. The communication with the Host Controller is ensured through Serial Peripheral Interface (SPI) Slave or Universal Asynchronous Receiver/Transmitter (UART). The X-NUCLEO-NFC03A1 is compatible with the ST Arduino UNO R3 connector pin assignment. Figure 1.
