This is not information that is readily available from the card. You could try the /identify command (if you have JCOP tools). It will at least give you a mask number for the JCOP platform. The clock speed is something that is not generally exposed.
I think you will need to contact NXP or your card supplier to get the product sheet to see what micro-controller they have. I have come across data sheets for different NXP micro-controllers online but nothing that says which one is in the J3A080. The only other documentation I have seen in the past was only available under NDA.
