M24LR16E-R antenna reference board with ESD protection, for reference only

ANT10-M24LR16E

Overview

The ANT10-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 65 mm RF etched antenna, and to an I2C bus on the other side.

A DSILC6-4P6 external ESD protection is mounted on the M24LR16E-R antenna inputs to increase the ESD immunity to ESD discharges on antenna up to the IEC. 61400-4-2 class 4 level. Please refer to the application note AN4326 “Increasing the M24LRXXE-R family ESD robustness on antenna using an external ESD protection” for more details about implementing an external ESD protection on M24LRXX antennas.
The ANT10-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 ANT10-M24LR16E can be used in conjunction with the DEMO-CR95HF-A demonstration boards.
