The application areas and applications of RFID cards are used in many ways all over the world and have already become part of our everyday life. The most important application areas of RFID smart cards are ID cards for time tracking, access control and ticketing applications. In addition, RFID cards offer high data security and multifunctional applications in a single plastic card, such as the combination of student ID and payment function for canteens. Health cards, bank cards, VIP cards and ID cards are also well-known applications of plastic cards with RFID 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 main difference between the EM4205 and EM4305:

- 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 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).


We also provide printing and encoding facility for all kinds of RFID cards, tags, key fobs, wristbands, etc. please contact us for pricing.
