ST25TB04K Product details

Description

1 Description The ST25TB04K is a contactless memory, powered by an externally transmitted radio wave.It contains a 4096-bit user EEPROM.The memory is organized as 16 blocks of 32 bits.The ST25TB04K 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% mo
