... Any attempt to fake the base station with a wrong transponder will be recognized immediately. For authentication, the base station transmits a challenge to the TK5561A-PP. This challenge is encrypted by both the IC and the base station. Both should possess the same secret key. Only then can the results be expected to be equal ...

... TK5561A-PP is powered. Writing is carried out by means of Atmel's patented writing method. To transmit data to the TK5561A-PP the read/write base station has to interrupt the RF field for a short time to create a field gap. The information is encoded in the number of clock cycles between two subsequent gaps. ...

... Writing Data into the TK5561A-PP A write sequence of the TK5561A-PP is shown in occurs by interrupting the RF field with short gaps. After the start gap the write opcode (10) is transmitted. The next 32 bits contain the actual data. The last 4 bits denote the destination block address. If the correct number of bits have been received, the actual data is programmed into the specified memory block ...

... Actual Device Behavior The TK5561A-PP detects a gap if the voltage across the coils decreases below a peak-to-peak value of about 800 mV. Until then, the clock pulses are counted. The number given for a valid (see ever, there are always more clock pulses being counted than were applied by the base station. ...
