Description

The ST25DV02K-W1/W2 device is an NFC/RFID tag IC with PWM outputs. It embeds an EEPROM memory of 2 Kbits, which can be divided for use-case flexibility.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.The device can be operated from a 13.56 MHz RFID reader or any NFC mobile phone.The contactless interface is based on ISO/IEC15693 and NFC Forum type 5 tag standards.
