MATRIX-M24SR：Matrix of multiple antenna for M24SR - Documentation purpose only

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.

Key Features

• 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.
• 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.
• 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 DSILC6-4P6 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)
• M24SR64-Y Dynamic NFC/RFID tag IC
