Need help with PN7462 configuration

Hello guys,


In my current project, I'm using PN7462 module from NXP. I need that module for the following:


1. To communicate with NFC card

2. To communicate with GSM module via UART interface. I need to have 1.8V level UART communication with GSM unit. Configuration commands for GSM should be sent from PN7462 to GSM. 

3. To control a few of the GPIO signals.


I'm reading PN7462 datasheet but I'm not sure I can digest it in a way to properly design my board. Would you guys be so kind to help me with the following:


1. How to supply the PN7462 module? Which power pins do I need to connect to power supply? How to achieve 1.8V for UART and GPIOs?

2. How to download the firmware on PN7462? Using SWD interface ?

3. How to properly design the antenna circuit for NFC communication. Is there any antenna chip available on the market or I need to print it on a PCB?


Thank you very much for your time and effort. Really appreciate it.

Looking forward to reading from you.
