General Description

EM4069 (previously named P4069) is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders, with an optional lock function to disable EEPROM write operations.

The IC is powered by picking the energy from a continuous 125 kHz magnetic field via an external coil, which together with the integrated capacitor form a resonant circuit.

The IC read out data’s from its internal EEPROM or ROM and sends it out by switching on and off a resistive load in parallel to the coil.
