I’m planning to use FM24CL16 EEPROMs in some projects. These are simple I2C EEPROMs but based on FRAM technology so they should last 10^14 of writes while typical 24Cxx chips only last one million. They are much cheaper on aliexpress than at my local distributor so I ordered 5pcs from this seller for about 40 cents each. Since my local distributor sells them 5 times more expensive I was a little bit suspicious if these are legit parts so I decided to test them.
