EM MICROELECTRONIC - MARIN SA EM4069 EM4169 128 bit Read/Write Contactless Identification Device with OTP function 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. Commands and EEPROM data updates can be executed by AM modulation of the 125 kHz magnetic field.
