A microcontroller includes a non-volatile memory storing secret data including a first set of security configurations, a second set of security configurations, and a state of the microcontroller being a first value indicating a first operation mode, a second value indicating a transition from the first operation mode to a second operation mode, or a third value indicating the second operation mode. If the state of the microcontroller is equal to the first value, it is operated in the first operation mode using the first set of security configurations. If the state of the microcontroller is equal to the second value, the secret data is erased and the microcontroller is operated in the second operation mode using the second set of security configurations. If the state of the microcontroller is equal to the third value, it is operated in the second operation mode using the second set of security configurations.
