description MATRIX-M24SR 2/6 docid025534 rev 2 1 description the MATRIX-M24SR board features various antenna designs for m24srxx-y dynamic nfc/rfid tag ic family combined on a single ready-to-use divisible pcb. each individual antenna features an m24sr6 4-y dynamic nfc/rfid tag ic connected to an rf antenna on one side, and to an i 2 c bus on the other side. all antennas are populated with m24sr64-y dynam ic nfc/rfid tag ic but are applicable to other densities. the MATRIX-M24SR antenna matrix allows syst em designers to eval uate the m24srxx-y family performance and ca pabilities and to get started with their design. the MATRIX-M24SR gerber files can be downloaded from http://www.st.com. figure 1. ant1, ant2, ant7, ant13 and ant14 block diagram 0 6 5 < 0 6 9 5 ) g l v d e o h $ & $ & * 1 ' 9 & & * 3 2 6 & / 6 ' $ n
