Sales Briefcase
  • The ST25DV02K-W1/2 is an ISO 15693 and NFC Forum Type 5 tag, with one or two pulse width modulation (PWM) outputs and 2 Kbits of electrically erasable programmable memory (EEPROM).

    It offers two interfaces. The first delivers up to 2x independent PWM output signals and the second is an RF link activated by the received carrier electromagnetic wave.
    The PWM outputs are configured at boot time, and can be updated live through RF link. RF and PWM are independently powered and can work in stand-alone mode.
    The ST25DV02K-W1/2 contains 256 bytes (64 blocks) of memory for User data. This memory is accessible through the RF interface, following ISO/IEC 15693 or NFC Forum Type 5 Tag recommendations.
    The device is based on technology and design solutions for which there are pending patents.
