Abstract: The invention relates to an electronic circuit including a substrate and at least one electronic component. Each electronic component includes at least one data port that receives data. The electronic circuit also includes, for each data port, a current injection terminal and a breakable electrical trace located in the thickness of the substrate and extending between the data port and the injection terminal. Each breakable electrical trace includes a fusible segment, and each breakable electrical trace is configured to break, by melting of the fusible segment, upon the injection, at the injection terminal, of an electric current having an intensity greater than a predetermined trace breaking threshold.

Abstract: The invention relates to an electronic circuit comprising a substrate and at least one electronic component (3, 6), each electronic component (3, 6) including at least one data port (12) for receiving data, the electronic circuit (2) further comprising, for each data port (12): a current injection terminal (8); a breakable electrical trace (10) located in the thickness of the substrate and extending between the data port (12) and the injection terminal (8), each breakable electrical trace (10) comprising a fusible segment (20) and being configured to break, by melting of the fusible segment (20), upon the injection, at the injection terminal (8), of an electric current (I) having an intensity greater than a predetermined trace breaking threshold.
