ST25DV02K-W2 Overview
1 Description 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.
