MATRIX-M24SR Datasheet, PDF (1/6 Pages) STMicroelectronics – Various antenna designs

MATRIX-M24SR
Antenna matrix for the M24SRXX-Y
Dynamic NFC/RFID tag IC family
Data brief
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.
