Key Technical Features:<\/span><\/h3>\n

Chip Type:<\/strong>
\nLow-frequency RFID IC utilising CMOS technology; operating frequency is 125 kHz<\/strong> (with partial support for 100\u2013150 kHz); compliant with ISO 11784\/11785<\/strong> standards and compatible with the FDX-B animal identification protocol.<\/p>\n

Memory Structure:<\/strong>
\n512-bit EEPROM, organised into 16 blocks of 32 bits each.
\nSupports a 32-bit Unique ID (UID),<\/strong> 32-bit read\/write password protection, and a 10-bit user-defined code.<\/strong><\/p>\n

Security Mechanisms:<\/strong>
\nSectors can be protected against unauthorised reading and writing via a 32-bit password<\/strong>.
\nSupports “lock bit”<\/strong> configuration, allowing EEPROM data blocks to be set to read-only mode to prevent unauthorised modification.<\/p>\n

Communication Features:<\/strong>
\nSupports multiple encoding schemes: Manchester, Bi-phase, Miller, etc.
\nMultiple data transmission rates are selectable (e.g., RF\/8, RF\/16, RF\/32, RF\/64).
\nRequires no external capacitors; features built-in rectification and voltage-limiting circuits to reduce hardware design complexity.<\/p>\n

Durability:<\/strong>
\nEndurance rating of over 100,000 read\/write cycles.
\nData retention period of up to 10 years.
\nWide operating temperature range of -40\u00b0C to +85\u00b0C, suitable for harsh environments.<\/p>\n
