... This device supports these security features: password checking, data locking, a one- way counter and a guaranteed unique serial number. The AT88RF020 includes an on-chip internal tuning capacitor that enables it to oper- ate with a single external coil antenna. This antenna completes the RFID channel. ...

... Pseudo Unique PICC Identifier: This PUPI field is a unique serial number permanently written into the device’s nonvolatile memory at the Atmel factory during wafer probe/test. It cannot be modified and is guaranteed to be unique for all AT88RF020 devices. Cus- tomers desiring serial numbers longer than 32 bits are expected to use other locations within the memory, including the Reserved field within Page 1 ...

... CRC bytes (start/stop bits, SOT, EOT and EGT are ignored). When the last bit of the CRC has been received, the value in the CRC register should be 0x0000. When the device transmits data, the CRC is computed based on all outgoing data bits. AT88RF020 3 ...

... CRC bytes. The least significant nibble of the first byte is the slot number, and if this matches the generated random number, then the ATQB response is generated. The chip will truncate the slot number field to match the value of N provided in the REQB command. The most significant nibble of this command is fixed at 0xA. AT88RF020 5 ...
