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
  • I2C bus connection
  • RF disable input connection with 30 kΩ pull-down resistor
  • GPO (General Purpose Output) output connection with 20 kΩ pull up resistor
  • 100 pF and 10 nF capacitors for VCC decoupling
