Features
• Ready to use printed circuit board including:
– ST25DV04K dual interface EEPROM
– 14 mm x 14 mm, 13.56 MHz dual layer etched antenna
– I2C test points
– RF event configurable general purpose output (GPO)
– Analog energy harvesting (EH) output
Description
The ANT7-T-ST25DV04K antenna reference board is a ready-to-use PCB that
features an ST25DV04K dual interface EEPROM connected to a 14 mm x 14 mm,
13.56 MHz etched RF double layer antenna on one side, and to an I2C bus on the
other side.
This demonstration board allows system designers to evaluate the ST25DV04K
performance and capabilities, and to get started with their design.
To demonstrate the energy harvesting function the ANT7-T-ST25DV04K can be used
in conjunction with the ST DEMO-CR95HF-A board.
The board design and the Gerber files can be downloaded from www.st.com.
If externally powered, supply has to be safety extra-low voltage (SELV) according to
EN60950-1 (< 5 V, < 15 W). The power supply shall be classified ES1 (electrical
energy source class 1), PS1 (electrical power source class 1) according to
EN62368-1.
