Write NT3H2211 NFC Command timing tACK

gb31 — Wed, 25 Aug 2021 08:48:24 GMT

When I use WRITE or FAST WRITE command NFC in order to write a page in NT3H2211 eeprom, how much time is the tACK time ( please see datasheet at page 55 ) ?

As the eeprom write is 4,7ms long, will I receive the ack of the write command after these 4,7ms or before?

In other words, when I receive an ack from the NFC write command sent by my app, am I sure that the data is correctlly written in the eeprom or no?

Thanks
