Hi, I'm designing an access control product that needs to support all MIFARE and ISO 15693 cards. I am already using an ARM Cortex-M3 part for some other features of the product and need to decide between using the CLRC663plus and the PN7150. It seems like the PN7150 is a no-brainer since it has all the library firmware already included thus saving on my MCU's flash, RAM and processing as well. Is there any disadvantage to using the PN7150 instead of the CLRC part that I'm not seeing? Even the pricing is better on the PN7150.
The two parts support the same standards according to their datasheet so I don't think there is any differentiation there. The target distance is contact to 10cm. Is there a range performance difference between the two parts?
