SIC7900 Radio Frequency IDentification (RFID) ASIC

Implementing standard Half-Duplex read-only animal RFID transponderFully compliant toISO11784,11785Animal RFID protocol128-bit Read-Only unique animal ID (ID Series Ordering: Country Code or Manufacturing Code)Supports user access to factory unique ROM ID (UID) preventing chip from cloningOperating frequency fc134.2 KHzBit Rate RF/16 FSKOn-Chip trimming capacitorsLong coupling range enabled by HDX telegram, immune to envelope noisesSmall die size suited to pets implantable glasstag formOperating temperature 25 to 85The SIC7900is a fully integrated Radio Frequency IDentification (RFID) ASIC for use in Half-Duplex Read-Only Animal electronic tagging transponders. The device is fully compliant to the ISO 11784/ 11785 HDX animal RFID data protocol and structure. The IC contains a 128-bit OTPROM.For optimum tuning of the antenna resonator, the IC incorporates on-chip trimming capacitors with on-the-fly auto-calibration after the tag's housing/moulding are done. The SIC7900 operates with only an external inductor, a resonant capacitor, and a single power supply decoupling capacito
