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
–I
2
C connector

OUT
) with a
10 nF capacitance filtering circuit
– RF WIP/BUSY output with 20 kΩ
pull-up
resistor, to indicate that an RF operation is
ongoing
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 I
2
C bus on the other side.
The ANT1-M24LR16E antenna allows system
designers to evaluate the M24LR16E-R
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 V
OUT
pin.
The ANT1-M24LR16E Gerber files can be
downloaded from http://www.st.com.
