Power consumption of NT3H2111 during RF eeprom read/write

Hello.

 

I am working with the NT3H2111 chip for an embedded system, where we need to write the EEPROM of the NT3H2111 when the internal system power is off. We are designing a small NFC antenna for power and communication, but cannot find precise information about the chips minimum power requirements during RF read/write. 

 

I have found the following thread: https://community.nxp.com/message/867423 where the power requirements during i2c read/write are discussed. The power requirement, in this case, is 240 uA, but is this the same power requirements when doing an RF read / write?

 

Thank you for your help, sincerely
