Abstract:
1. An electronic system comprising a printed circuit contained in a package and a protection device comprising: conductive tracks supported by the printed circuit and each of the conductive tracks having a free end; a first integrated circuit connected to the conductive tracks and the first integrated circuit capable of detecting a variation of the capacitance seen by each conductive track; and a second integrated circuit, confounded with the first integrated circuit, the second integrated circuit comprising a memory configurable to select some of the conductive tracks, the second integrated circuit being capable of determining that an authorized or unauthorized access is occurring from the detection of the variation of the capacitance seen by at least one of the selected conductive tracks, wherein the printed circuit is rigid, the electronic system comprising an electronic component connected to the printed circuit by a flexible printed circuit, at least one of said conductive tracks extending to the flexible printed circuit.
