Trade conditions | Special offers                      EM4305 EUR 5.00 EM4305 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. • 512 bit EEPROM organised in 16 words of 32 bit • 32 bit unique identifier (UID) • 32 bit Password read and write protection Contact us for datasheets or volume orders. 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 EM4305 supports bi-phase and Manchester data encodings. The EM4305 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).
