STMicroelectronics ST25DV-PWM-ESET

The ST25DV-PWM-eSET is a dynamic NFC tag evaluation board based on the ST25DV02K-W2 device, an NFC/RFID tag IC with PWM outputs embedding a 2-Kbit EEPROM that can be partitioned for use-case flexibility. The PWM output can be programmed independently and securely, allowing the user to address a large number of applications. 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 by any NFC mobile phone.

• Ready-to-use printed circuit board with:
• 22 x 38 mm2 single layer inductive antenna, etched on the PCB
• Two LEDs illustrating duty cycle of PWM outputs
• Contactless interface
• 28.5 pF internal tuning capacitance
• Memory and data protection
• 2-Kbit EEPROM
• Up to four independent areas
• TruST25™ digital signature mechanism for authentication
