I2C Smart Card memory

[pedja089]

For test, try to write single byte every time, and wait 5ms, between each write.
That would eliminate page write issue.

As long as the power is on, data appears to be written.

Including the one byte test. But if card is removed and re-inserted, data gets lost.

Then that doesn't have anything with page write.
Just guessing, maybe there are only some serial number permanently stored in eeprom, and other location are unimplemented?

[Ioannis]

It is very bizzare that it seems to write succesfully in every location for as long as the power is ON.

I'll some more tests and report back.

I have also available a couple of SLE4442 but have never tried that for writing.
