Hi,
I'm going to use the MFRC522 in a design (I know there is a new version recommended but the client really wanted to use this chip).
But when finding a crystal for it, the datasheet specifies a maximum power dissipation of 100mW, but I think and hope this should be 100uW as there are no crystals available that I know of that can dissipate 100mW.
Thanks,
Best regards,
