STMicroelectronics MATRIX-M24SR Antenna
STMicroelectronics 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.
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.
