Which is the part code of this ic? I searched for the printed code but found
nothing. I think it's a serial eeprom. I'm looking for its datasheet.

The top one is the model number (or part of it),the 2nd is the
batch number and the last is a date code.

Using the top code I find nothing about this chip. I suspect some digits are
missing. For example a similar ic is coded as LC56, and it is the 93LC56.
Do you, or someone else, know the manufacturer (from the NN maybe)?

There is also a reference to RFID.

The photo shows the whole pcb. It is connected to a coil. Of course it's a
RFID chip, from laser toner cartridges.

Thanks for the links. But they don't help much. The first link comes form
someone which sells the programming service, but unfortunately he is in
China. The second link, just someone else -like me- asking for the same
chip.
Is there any chance to quess the manufacturing company?

Could it be manufactured by Microchip? The pins corresponds to a Microchip
specific chip, but the part number is total different.

My Epson C45 bubblejet printer ink cartridge also has such a counter
chip. Whenever my friend refils the ink for me, he has to put a small
adaptor pressing against the small pcb on the cartridge. The adaptor
has a green and a red LED and one of the led will flash for a while
then the cartridge is reset and can be reused. I dont know if there
is such an adaptor for the laser printer. But if you can wait long
enough, people will always came out with a new adaptor for that
model. The Chinese are especially very fast and keen in doing this.
may be I should ask him where he got the adaptor.

At the moment, there is no adapter for this chip. On the other hand the chip
I'm asking is a contactless (RF) chip.

P.S. older epson chips were easy. Now, epson designed and uses a new chip,
and it confuses many people...

I doubt it would help you.
Since the neature of the device is some sort of revenue protection
security, you will have little chance of getting real data on it.
