Overview
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.
At power–up the EM4069 goes in default mode in which it constantly (without any pause) transmits 128 bits from the EEPROM.
Upon transmission of a specific command, the 64 bits unique laser code is output.
Additional commands for writing and lock data in EEPROM are available.
