Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hello,I would like to implement the M24SR02 in my design, with an NFC antenna.The problem is that, in order to have a resonant frequency of 14.2MHz, the inductance of the NFC antenna needs to be around 5µH in order to resonate with the 25pF capacitan...
I am working on M24Sr64-Y chip. I am able to read Chip using I2C as per application note AN4433. But in that application note there is nothing mentioned about writing to the NFC chip using I2C. So I followed commands as for RF writing,Because Reading...

I am trying to achieve read range of 10cm or more on an antenna attached to M24SR chip. I am currently getting a read range of 5.5cm How can I increase the read range?Thanks in advance.
I need to specify an RFID IC for bidirectional data exchange with an Android mobile phone. I will be using the NFC to update the firmware on an MCU in the system with a flash size of 32kB. The other application is the for the system to transfer up to...
I have 3 of the ST25R3911B-Disco boards and they are working great with discovery gui version 1.1.22.0 on a windows 10 pro machine. I needed to set up a second pc and can now only get the gui version 1.2.2 when I try to connect to the new version I f...
