Hi,

   

I am looking for advise on of-topic subject, hoping for vast experience of forum users. 

   

I am looking for a solution to match two packages: a driver board and LED package by installing some ID chip into LED package. So before turning on, the driver board can check that it has matched LED attached. It would be nice if some extra ~64 bytes of information could be stored it such memory, such as driving voltage, current, etc., and package size would be small as possible, maybe bodyless, with 3 legs or less (power, 1-wire/SPI and GND).

   

Thank you,
