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
