FLEX-M24LR04E 45 mm x 75 mm flexible antenna reference board for the M24LR04E-R Dual Interface EEPROM

2022-08-02

●Description
■The FLEX-M24LR04E antenna reference board is a ready-to-use flexible PCB that features an M24LR04E 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 FLEX-M24LR04E antenna allows system designers to evaluate the M24LR04E performance and capabilities, and to get started with their design.
■To demonstrate the energy harvesting function, the FLEX-M24LR04E can be used in conjunction with ST DEMO-CR95HF-A demonstration board.
■The application can be powered directly from the M24LR04E VOUT pin.
●Features
■Ready-to-use flexible printed circuit board (PCB) including
▲45 mm x 75 mm 13.56 MHz inductive antenna etched on the PCB
▲100 μm thickness PCB (Kapton)
▲M24LR04E-R Dual Interface EEPROM
▲Connection for I2C bus
▲Energy harvesting output (VOUT) with a10nF capacitance filtering circuit
▲RF WIP/BUSY output with 20 kΩ pull-up resistor, to indicate that an RF operation is ongoing
