X-NUCLEO-NFC02A1

X-NUCLEO-NFC02A1 Dynamic NFC tag IC expansion board based on M24LR04E for STM32 Nucleo Data brief Description The X-NUCLEO-NFC02A1 is a dynamic NFC/RFID tag board based on M24LR04E-R, for expansion of STM32 Nucleo boards. The M24LR04E-R is an NFC Type V/RFID tag IC with a dual-interface 4 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) that also features an I2C interface. Features • STM32 expansion board based on the M24LR04E-RMN6T/2 Dynamic NFC/RFID tag • Up to 4 Kbit memory with NDEF support • 30 mm x 30 mm 13.56 MHz double layer inductive antenna etched on the PCB The EEPROM is organized as 512 x 8 bit in the I2C mode and as 128 x 32 bit in RF mode. It can be operated either from an external power supply or directly powered by the received carrier electromagnetic field. The tag provides an user configurable digital output pin toggling during either RF Write in Progress or RF Busy mode. • Scalable solution, capable of cascading multiple boards for larger systems The M24LR04E-R provides an Energy Harvesting mode. When activated, the M24LR04E-R delivers the excess energy coming from the RF field on the Vout analog pin. In case the RF field strength is insufficient or when Energy Harvesting mode is disabled, the analog output pin Vout goes into high-Z state and Energy Harvesting mode is automatically stopped. • Free comprehensive development firmware library and example for M24LR04E-R, compatible with STM32Cube firmware The X-NUCLEO-NFC02A1 is compatible with the Arduino™ UNO R3 connector pin assignment and interfaces with the STM32 MCU via the I2C pins. • Compatible with STM32 Nucleo boards • Equipped with Arduino™ UNO R3 connector • Self powered or powered through the Arduino™ UNO R3 connectors • 3 general purpose LEDs • FCC verified • RoHS compliant June 2016 DocID026681 Rev 4 For further information contact your local STMicroelectronics sales office. 1/10 www.st.com Contents X-NUCLEO-NFC02A1 Contents 1 Block diagram and hardware schematics . . . . . . . . . . . . . . . . . . . . . . . . 5 2 Federal Communications Commission (FCC) and Industry Canada (IC) Compliance Statements . . . . . . . . . . . . . . . . . . . . 7 2.1 2.2 3 2/10 FCC Compliance Statement . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.1.1 Part 15.19 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.1.2 Part 15.105 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.1.3 Part 15.21 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Formal notices required by the Industry Canada . . . . . . . . . . . . . . . . . . . . 7 2.2.1 Compliance Statement . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.2.2 Déclaration de conformité . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 DocID026681 Rev 4 X-NUCLEO-NFC02A1 List of tables List of tables Table 1.
