Hi, I'm working now with secure NFC tags and need to select the propper version of the IC NT4H242.
Reading the datashset https://www.nxp.com/docs/en/data-sheet/NT4H2421Tx.pdf i found 3 types of versions:
NT4H2421TTDUF - 8 inch wafer (sawn; 75 μm thickness; Au Bumps), 256 Byte NDEF Message, 128 Byte User Memory, Ci = 50 pF
NT4H2421TSDUF - Service version with preprogrammed NDEF message and keys, 8 inch wafer (sawn; 75 μm thickness; Au Bumps), 256 Byte NDEF Message, 128 Byte User Memory, Ci = 50 pF
NT4H2421TCDUF - Customer configurable version, 8 inch wafer (sawn; 75 μm thickness; Au Bumps), 256 Byte NDEF Message, 128 Byte User Memory, Ci = 50 pF
What exact modification should i use/select to be able to set my own keys and set my own NDEF message?
As i understand the "service" version is already programmed, so let skip it. So the question what is the difference between "empty" (TDUF) and "customer" (CDUF) versions? Which exact version will alllow me to made some configuration?
