EM4102 Card

The EM4102 (previously named H4102) is a CMOS integrated circuit for use in electronic Read Only RF Transponders. The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. By turning on and off the modulation current, the chip will send back the 64 bits of information contained in a factor programmed memory array. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The EM4102 has several metal options which are used to define the code type and data rate. Data rates of 64, 32 and 16 periods of carrier frequency per data bit are available. Data can be coded as Manchester, Biphase or PSK. Due to low power consumption of the logic core, no supply buffer capacitor is required. Only an external coil is needed to obtain the chip function. A parallel resonance capacitor of 78 pF is also integrated.

Low Frequency (LF) RFID is a band on the radio frequency spectrum that typically operates between 125 kHz and 134 kHz. Technically, LF applications can operate on a larger bandwidth from 30 kHz to 300 kHz; however, the specific band varies from country to country and depends on frequencies set aside for radio and marine life tracking.LF RFID communicates in a similar fashion to HF/NFC RFID in that it uses electromagnetic coupling to send and receive signals. Below are a few facts about LF RFID:1:Only small amounts of data can be stored on the tags.2:LF tags are typically smaller than other types of RFID tags.3:LF systems have shorter read ranges than both HF and UHF RFID.
