EM4205 Card

EM4205/4305 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders. It is suitable for low cost solutions like animal tagging applications. The IC communication protocol is compatible with the EM4469/4569 family. The main difference between the EM4205 and EM4305 is that:  EM4305 are bumped with enlarged pads for the two coil inputs. The enlarged bumped pads of the EM4305 transponder are intended for direct antenna connection avoiding the need of a module.  EM4305 offers a 330pF resonant capacitor version The IC is powered by picking up energy from a continuous 125 kHz magnetic field via an external coil, which together with the integrated capacitor form a resonant circuit. The IC reads out data from its internal EEPROM and sends it out by switching on and off a resistive load in parallel to the coil using a large modulation index. Commands and EEPROM data updates can be executed by 100% AM modulation of the 125 kHz magnetic field. The EM4205/4305 supports bi-phase and Manchester data encodings. The EM4205/4305 operating modes are stored in the EEPROM configuration word. All EEPROM words can be write-protected by setting protection bits. The IC contains a factory programmed 32 bit unique identifier number (UID)

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.
