RFID tag EM4100 EM marin:
Read Only Contactless Identification DeviceDescriptionThe EM4100 (previously named H4100) is a CMOSintegrated circuit for use in electronic Read Only RFTransponders. The circuit is powered by an external coilplaced in an electromagnetic field, and gets its masterclock from the same field via one of the coil terminals. Byturning on and off the modulation current, the chip willsend back the 64 bits of information contained in a factor pre-programmed memory array.The programming of the chip is performed by laser fusingof polysilicon links in order to store a unique code on eachchip.The EM4100 has several metal options which are used todefine the code type and data rate. Data rates of 64, 32and 16 periods of carrier frequency per data bit areavailable. Data can be coded as Manchester, Biphase orPSK.Due to low power consumption of the logic core, no supplybuffer capacitor is required. Only an external coil isneeded to obtain the chip function. A parallel resonancecapacitor of 74 pF is also integrated.Features64 bit memory array laser programmableSeveral options of data rate and coding availableOn chip resonance capacitorOn chip supply buffer capacitorOn chip voltage limiterFull wave rectifier on chipLarge modulation depth due to a low impedancemodulation deviceOperating frequency 100 - 150 kHzVery small chip size convenient for implantationVery low power consumptionApplicationsLogistics automationAnticounterfeitingAccess controlIndustrial transponder
