1. NFC ST25R95 Can I process if I don't use the MCU to control?

2. Can I boot up voltage to 10V for pin TX1 and TX2 for differential pair?

Best,

Hi, 

In AN4974 (antenna matching network for ST29R391x device), In chapter 6.2.1 in Simulation S-parameter and Transition model, what is the tool used for simulation in this case?

Hi,

you can download the STSW-ST25R004 (Antenna Matching Tool for ST25R NFC/HF reader family) package to performs transient, AC, and S-parameter simulations of the calculated antenna schematic.

Hi, 

My application used ST25R3916B for transmit power for the card only.

1. Is it possible to leave the EXT_LM pin unused or exclude external load modulation from my application?
2. Can I use the testing point only on the pin EXT_LM pin?
Best,
