Tamper-resistant microcontroller
By the Annex wording, a tamper-resistant microcontroller points to the important class II class (Annex III, class II, point 4). The route that class asks for: eU-type examination (module B then C), full quality assurance (module H), or a European cybersecurity certification scheme at assurance level at least substantial where available (Art. 32(3)); internal control is not among them.
