The ST25DV-PWM series of dynamic NFC/RFID tags offers a 13.56 MHz long-range interface compatible with NFC phones and readers. The ST25DV02K-W1/W2 device is an NFC/RFID tag IC with PWM outputs.

The PWM output can be programmed independently and securely, allowing a large field of application. The IC provides live update of PWM parameters by contactless interface, extending the user experience. 

Contactless interface

  • Based on ISO/IEC 15693 and NFC Forum Type 5 Tag

Pulse width modulation outputs

  • Up to 2x independent outputs:
    - 1x PWM output with ST25DV02K-W1
    - 2x PWM outputs with ST25DV02K-W2
  • From 488 Hz to 31250 Hz
  • 62.5 ns pulse width resolution:
    - From 15-bit resolution at 488 Hz to 9-bit resolution at 31.25 kHz
  • Accuracy: ±10% over temperature range
  • No need for external oscillator
  • Supply voltage from 1.8 V to 5.5 V, independent from contactless interface
