Wholesale miniature LF 125KHz microchip rfid animal tag EM4305 chip

Chip Description:

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 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).
