製品概要

概要

The ST25TB02K is a contactless memory, powered by an externally transmitted radio wave. 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.
