Hello @user_ahmed 

PN7160/1 is a frond-end product, which cannot  work alone, must work together with Host, like MCU. So, you mentioned "esp", is it a type of Host? if so, esp can communicate with PN7161 via I2C or SPI.
Also, you bought the IC, which has default FW, when it worked with the Host, its FW can be updated to the latest version.

any library available to communicate between host and ic ?

Hello @user_ahmed 

It's recommended that you can refer to SW6705 - PN7160 NXP-NCI MCUXpresso Example Project, which is based on MCU projects.

Please log in Plug-n-Play NFC Frontend with Integrated Firmware | NXP Semiconductors to download it.
