Hello Kiranym, The ST25R3916B is a perfect choice. As far as I know, for US and Canadian Market you have to fulfill FCC standards.For EU you need to comply with CE / RED. This can depend on your type of application. The best approach is, if you consu...
Hello Shay, Below my comments due to your schematic from 2024-08-04 02:07 AM.Decoupling caps:You have both decoupling pairs on VDD_DR and VDD_RF. You could put C30 and C31 to d.n.p. only one pair of decoupling caps is required here. To have a spare ...
Hello Lisheng Zou, For now, lets assume max amplitude and target amplitude is the same. (Max is just a different target).The target phase algorithm can be beneficial if you want to end up with the same/ good wave shapes along de-tuning.(dependent on ...
Hello Lisheng Zou, The amplitude algorithm adjusts to the highest amplitude of antenna voltage (=highest amplitude on RFI).In most cases this is at the lowest possible target matching impedance while still being on the resonance sweet spot - especial...
Hello FYRSing, Our Eval boards allow switching between technologies. Using our demo software you can find ISO14443 Type A and B tags as well as Felica, ISO15693 and other technologies.Nevertheless there is a reason for having different technologies. ...
