description X-NUCLEO-NFC03A1 2/7 docid026679 rev 4 1 description the X-NUCLEO-NFC03A1 (see figure 1 ) is an nfc card reader evaluation board based on cr95hf-vmd5t to enable expansion of the stm32 nucleo boards. the cr95hf manages frame coding and decoding in reader mode for standard applications, such as nfc, pr oximity and vicinity standards. the cr95hf embeds an analog front end to provide the 13.56 mhz air interface. the cr95hf supports iso/iec 14443 type a and b, iso/iec 15693 (single or double subcarrier) and iso/iec 18092 communica tion protocols, besides being mifare ? classic compatible (a) . it also supports the detection, readin g and writing of nfc forum type 1, 2, 3 and 4 tags. the cr95hf features an optimized power ma nagement scheme, including tag detection mode. 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. functional block diagram a. mifare and mifare classic are registered trad emarks of nxp b.v. and are used under license. 0 6 9 p p [ p p $ q w h q q d o r r s 6 3 , & 5 + ) , 5 4 $ u g x l q r ? f r q q h f w r u 8 $ 5 7 1 x f o h r s r z h u v x s s o \ $ u g x l q r ? f r q q h f w r u $ u g x l q r ? f r q q h f w r u $ u g x l q r ? f r q q h f w r u
