NFC reader ST25R3916B EXT_LM pin

Dalik

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,
Dalik LIM

Hi Dalik,

 

not sure I completely understand: Using EXT_LM is a possibility in the chip. Technically it can work without. Foreseeing a testpoint is always a good idea.
