The 24Cxx series is a series of EEPROMs that are accessed through I²C.

Blood Glucose Monitor Calibration Stick

A while back I purchased one of these Blood Glucose Monitors:

What makes them interesting is that the actual test strips are packaged together depending on calibration value. The value is indicated on the canister:

And each batch comes with a calibration stick which needs to be inserted into the reader before use.

These calibration sticks caught my curiosity and I had to rip one of them apart. Inside is a very simple circuit consisting of a capacitor, a few resistors and an IC labelled "24C08A". Digging into the
