It contains a 2048-bit user EEPROM. The memory is organized as 64 blocks of 32 bits. The ST25TB02K is accessed via the 13.56 MHz carrier. Incoming data are demodulated and decoded from the received amplitude shift keying (ASK) modulation signal and outgoing data are generated by load variation using bit phase shift keying (BPSK) coding of a 847 kHz sub-carrier. The received ASK wave is 10% modulated. The data transfer rate between the ST25TB02K and the reader is 106 kbit/s in both reception and emission modes. The ST25TB02K follows the ISO 14443 - 2 Type B recommendation for the radio-frequency power and signal interface. Figure 1. Logic diagram ST25TB02K AC1 Power Supply Regulator ASK 2 Kbit User Demodulator EEPROM BPSK Load Modulator AC0 The ST25TB02K is specifically designed for short range applications that need re-usable products. The ST25TB02K includes an anticollision mechanism that allows it to detect and select tags present at the same time within range of the reader. The anticollision is based on a probabilistic scanning method using slot markers. Table 1. Signal names Signal names Description AC1 Antenna coil AC0 Antenna coil The ST25TB02K contact-less EEPROM can be randomly read and written in block mode (each block containing 32 bits). The instruction set includes the following nine commands: Read block Write block Initiate Pcall16 Slot marker Select Completion Reset to inventory Get UID DS11469 - Rev 6 page 2/48
