摘要
In one form, an integrated circuit includes a plurality of electromagnetic fault injection (EMFI) sensors and a security management circuit. Each EMFI sensor includes a sense loop having a conductor around a corresponding portion of logic circuitry whose operation is affected by an electromagnetic pulse, and a detector circuit coupled to the sense loop and having an output for providing a pulse detection signal in response to a pulse of at least a predetermined magnitude. The security management circuit performs a protection operation to secure the integrated circuit in response to an activation of a corresponding pulse detection signal of one of the plurality of EMFI sensors.
