ANT2-M24LR16E 20 mm x 40 mm antenna reference board for the M24LR16E-R Dual Interface EEPROM Data brief Features Ready-to-use printed circuit board (PCB) including - 20 mm x 40mm 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 - RF WIP/BUSY output with 20 k pull-up resistor, to indicate that an RF operation is ongoing performance and capabilities, and to get started with their design. Description The ANT2-M24LR16E antenna reference board is a ready-to-use PCB that features an M24LR16ER Dual Interface EEPROM IC connected to a 20 mm x 40 mm 13.56 MHz etched RF antenna on one side, and to an I2C bus on the other side. To demonstrate the energy harvesting function, the ANT2-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 ANT2-M24LR16E Gerber files can be downloaded from http://www.st.com. The ANT2-M24LR16E antenna allows system designers to evaluate the M24LR16E-R Figure 1. Block diagram 6/54 &ILTERING CIRCUIT 6/54 6## 6## K !# 2& 7)0"539 2& 7)0"539 -,2% 2 !# 3#, )# BUS 3$!
