ROBOT-M24LR16E-A Evaluation board for the M24LR16E-R dual interface EEPROM Data brief Features 20 mm x 40 mm 13.56 MHz inductive antenna etched on PCB M24LR16E-R dual interface EEPROM IC connector Energy harvesting output (V ) with a OUT capacitance filtering circuit RF WIP/BUSY output with 20 k pull-up resistor, to indicate that an RF operation is ongoing Description The ROBOT-M24LR16E-A is a ready-to-use PCB that features an M24LR16-R dual interface EEPROM IC connected to an IC bus and a 20 mm x 40 mm 13.56 MHz etched RF antenna. It also features two LEDs, powered by the M24LR16E-R V pin and an output connector. OUT The ROBOT-M24LR16E-A has three functions: Switch in the LED position: the robot demonstrates energy harvesting by powering the LED when a sufficient magnetic field is captured. Switch in the V position: the energy OUT captured from the electromagnetic field is used to power an external application through the V OUT pin. RF WIP/BUSY function: for the RF WIP/BUSY pin of M24LR16E-R, please refer to the M24LR16E-R datasheet for further details. To demonstrate the energy harvesting function, the ROBOT-M24LR16E-A can be used in conjunction with ST DEMO-CR95HF-A demonstration board.
