Hello Stéphano,1) all our NFC chip embed an internal tuning capacitance and you just need to design the appropriate antenna inductance to get resonance at 13.56MHz. For ST25DV family, internal tuning capacitance to calculate antenna is 28.5pF. Resona...
Hello Domenico,the measured equivalent inductance of ANT7-M24SR64 is 4.76uH, leading to a resonant frequency around 14.1MHz.A tuning frequency of 13.56MHz will improve the powering distance and the communication distance. Feel free to adjust the freq...
Hello,ST25DV64KC-DISCO kit offer a 50x40mm PCB antenna and a 25x20mm flex PCB Antenna.ANT7-T-25DV64KC kit offers a 14x14mm double layer PCB antenna.ST25DV64KC only differs from ST25DV04KC in memory size (64Kbits vs 4Kbits), RF performance, commands, ...
Hello Suraj,the tuning capacitance value specified in datasheet corresponds to the value monitored in production at low voltage (1Vpeak). The typical tuning capacitance at minimum operating voltage that has to taken into account for antenna tuning is...
hello,for bumped dies flip chip assembly, conductive or non conductive ink are commonly used by inlay manufacturers. This process requires special machine to apply glue, position the die on the antenna pads with a given pressure and cure the glue.For...
