Subcarrier Frequency:<\/strong> 847 kHz (for BPSK encoded data return)<\/p>\n

Data Transfer Rate:<\/strong> 106 kbit\/s (Bidirectional high-speed communication)<\/p>\n

Storage Capacity:<\/strong><\/p>\n

Total User Space:<\/strong> 4096-bit (4Kbit) EEPROM<\/p>\n

Storage Structure:<\/strong> 16 blocks \u00d7 32 bits<\/p>\n

Unique Identifier (UID):<\/strong> 64-bit unchangeable chip ID<\/p>\n

Counter Function:<\/strong> Integrated two 32-bit decrementing counters with a tear protection mechanism<\/p>\n

OTP Area:<\/strong> Resettable one-time programmable area for status marking<\/p>\n

Anti-collision Mechanism:<\/strong> Supports simultaneous reading of multiple tags to avoid signal interference<\/p>\n

Write\/Erase Cycles:<\/strong> Up to 1 million write\/erase cycles<\/p>\n

Data Retention Time:<\/strong> 40 Over 1 year old<\/p>\n

Power supply:<\/strong> Passive design, powered by the reader’s electromagnetic field induction<\/p>\n

Internal tuning capacitor:<\/strong> 68 pF, simplifying antenna matching design<\/p>\n

Key Features<\/h2>\n

Large-capacity storage:<\/strong> Compared to the ST25TB512’s 512-bit, the ST25TB04K offers 8 times the storage space, suitable for applications requiring more data recording.<\/p>\n

Dual counter design:<\/strong> Natively supports decrementing counting logic, suitable for scenarios such as bus tickets and event entry control.<\/p>\n

Anti-tear protection mechanism:<\/strong> Ensures data integrity during communication interruptions, preventing counting errors or information loss.<\/p>\n

High anti-interference capability:<\/strong> Optimised RF interface design ensures stable operation even in complex electromagnetic environments.<\/p>\n

Low-power passive architecture:<\/strong> No battery required; simply attach to cards, tags, wristbands, etc.<\/p>\n

Supports reusable systems:<\/strong> Optimised for reusable scenarios, such as transportation cards and rental device authorisation.<\/p>\n

Why Choose the ST25TB04?<\/h2>\n

With 4 Kbit memory and reliable CMOS fabrication, the ST25TB04 strikes a balance between storage capacity and durability for a wide range of contactless applications. Its compatibility with ISO standards and passive power design ensures easy integration and long-term maintenance-free use, perfect for secure access control and payment solutions.<\/p>\n

Application Areas<\/h2>\n

Public Transportation:<\/strong> Subway multi-trip cards, bus monthly passes, shared bicycle electronic keys<\/p>\n

Event Management:<\/strong> Multi-day passes or limited-entry tickets for sporting events and concerts<\/p>\n

Asset Lifecycle Tracking:<\/strong> Industrial equipment maintenance records, instrument usage statistics<\/p>\n

Brand Anti-counterfeiting and Traceability:<\/strong> NFC verification tags on high-end wines, luxury goods, and pharmaceutical packaging<\/p>\n

Smart Access Control:<\/strong> Visitor access cards, temporary access passes, electronic badges for exhibitions<\/p>\n

Medical Consumables Management:<\/strong> Reagent bottle usage tracking, reusable instrument sterilization cycle records<\/p>\n

Unlike the Mifare series, the ST25TB04K uses the Type B protocol, offering stronger signal penetration and anti-interference capabilities, and natively supports counting functions, making it more suitable for industrial applications requiring status management and data persistence.<\/p>\n
