General description
The 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 EM4469/4569 family. In its EM4305 version, the circuit comes with enlarged pads and gold bumps for the two coil inputs. These pads are intended for direct
antenna connection without need of a module support. In addition to the other available resonnant capacitor values, the EM4305 is also available with 330pF.

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 several Bi-phase and Manchester data encodings.
The 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 UID number.
