128bit OTP/RW Transponder
Data encoding schemes
Manchester
For a “1” bit, there is a transition from 0 to 1 in the middle of the bit period. Reciprocal, for a “0” logic bit
there is a transition from 1 to 0 in the middle of the bit period.
Biphase
At the beginning of each bit, a transition will occur. A logic bit “1” will keep its state for the whole bit duration and a
logic bit “0” will show a transition in the middle of the bit duration.

Flow Chart.
Upon entering the RF field, the transponder "sees" increasing amplitude of the voltage between COIL and GND
pins. It passes through a POR sequence. Depending on the configuration bits it will enter the appropriate mode.
