Features

■Ready-to-use printed circuit board (PCB) including

–45 mm x 75 mm 13.56 MHz inductive antenna etched on the PCB

–M24LR16E-R Dual Interface EEPROM

–I2C connector

–Energy harvesting output (VOUT) with a 10 nF capacitance filtering circuit

Description

The ANT1-M24LR16E antenna reference board is a ready-to-use PCB that features an M24LR16E- R Dual Interface EEPROM IC connected to a

45 mm x 75 mm 13.56 MHz etched RF antenna on one side, and to an I2C bus on the other side.

The ANT1-M24LR16E antenna allows system designers to evaluate the M24LR16E-R

Data brief

performance and capabilities, and to get started with their design.

To demonstrate the energy harvesting function, the ANT1-M24LR16E can be used in conjunction with ST DEMO-CR95HF-A demonstration board.

The application can be powered directly from the M24LR16E-R VOUT pin.

The ANT1-M24LR16E Gerber files can be downloaded from http://www.st.com.

Associated firmware and PC software

The ANT1-M24LR16E board is supported by a PC software, the Dual Interface EEPROM tool software, that allows to configure and control the energy harvesting. This software is available from http://www.st.com.

Refer to application note AN3954 “Developing your own Visual Basic or C/C++ application on a DEMO-CR95HF-A demonstration board”, for how to adapt the PC software for your application.
