| Chip functions | The ST25TB04K is a contactless memory powered by an externally transmitted radio wave. It contains a 4096-bit user EEPROM organized into 16 blocks of 32 bits each. Access to the ST25TB04K is through a carrier at 13.56 MHz. Incoming data is demodulated and decoded from the received amplitude shift keying (ASK) modulation signal, while outgoing data is generated by load variation using bit phase shift keying (BPSK) coding of an 847 kHz sub-carrier. The received ASK wave is modulated at 10%. The data transfer rate between the ST25TB04K and the reader is 106 kbit/s in both reception and emission modes. The ST25TB04K follows the ISO 14443-2 Type B recommendation for radio-frequency power and signal interface. It is designed for short-range applications that require reusable products. Additionally, the ST25TB04K includes an anti-collision mechanism that allows for the detection and selection of tags present simultaneously within the reader's range. The anti-collision is based on a probabilistic scanning method using slot markers. |
