ST25R3915-AQWT Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the ST25R3915-AQWT is 148 kHz, but it can also operate at lower frequencies such as 125 kHz, 100 kHz, and 50 kHz.
  • The ST25R3915-AQWT has an integrated antenna tuning circuit that allows for automatic tuning of the antenna to optimize its performance. This is done through the use of a tuning capacitor and a tuning algorithm that adjusts the capacitance value based on the operating frequency and the antenna's characteristics.
  • The maximum distance that the ST25R3915-AQWT can operate at depends on various factors such as the operating frequency, the power of the transmitter, and the sensitivity of the receiver. However, in general, the ST25R3915-AQWT can operate at distances of up to 10 cm (4 inches) or more in ideal conditions.
  • Yes, the ST25R3915-AQWT supports multiple protocols including ISO/IEC 14443A, ISO/IEC 14443B, and FeliCa. It also supports proprietary protocols and can be customized to support other protocols as well.
  • The ST25R3915-AQWT has a low power consumption design that allows it to operate at low power modes to conserve energy. It also has a power-down mode that can be used to further reduce power consumption when the device is not in use.
