MATRIX-M24SR

MATRIX-M24SR Antenna matrix for the M24SRXX-Y Dynamic NFC/RFID tag IC family Data brief • Various antenna designs – 45 mm x 75 mm 13.56 MHz inductive antenna etched on the PCB (ANT1) – 20 mm x 40 mm 13.56 MHz inductive antenna etched on the PCB (ANT2) – 14 mm x 13.5 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT7) – 45 mm x 65 mm 13.56 MHz inductive antenna etched on the PCB with a DSILC64P6 external ESD protection (ANT10) – 4.7 µH SMD-inductor based antenna (ANT11) – 2 spare circuits for customer antenna development (ANT12) – Metal Tag 13 .56 MHz inductive antenna etched on the PCB (ANT9) – 20 mm round 13.56 MHz double layer inductive antenna etched on the PCB (ANT13) – 31 mm x 30 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT14) Features • M24SR64-Y Dynamic NFC/RFID tag IC • I2C bus connection Ready-to-use printed circuit board including 10 divisible antenna boards. Each of those antenna board can be connected to an MCU thanks to the I2C interface. • RF disable input connection with 30 kΩ pulldown resistor The MATRIX-M24SR antenna boards are based on the M24SR64-Y device which is compatible with NFC phones. As such, any NFC phone can communicate with those antenna boards. • 100 pF and 10 nF capacitors for VCC decoupling December 2013 • GPO (General Purpose Output) output connection with 20 kΩ pull up resistor DocID025534 Rev 2 For further information contact your local STMicroelectronics sales office. 1/6 www.st.com Description 1 MATRIX-M24SR Description The MATRIX-M24SR board features various antenna designs for M24SRXX-Y Dynamic NFC/RFID tag IC family combined on a single ready-to-use divisible PCB. Each individual antenna features an M24SR64-Y Dynamic NFC/RFID tag IC connected to an RF antenna on one side, and to an I2C bus on the other side. All antennas are populated with M24SR64-Y Dynamic NFC/RFID tag IC but are applicable to other densities. The MATRIX-M24SR antenna matrix allows system designers to evaluate the M24SRXX-Y family performance and capabilities and to get started with their design.
