A programmable device, characterized in that it includes: - a programmable component capable of managing its own configuration, from a configuration file, having an output able to send an inhibiting signal upon successful configuration of the programmable component and an input (CONFIG) able to receive a reconfiguration signal; - a circuit for the automatic burn-in of the configuration of the programmable component, having: - means for selecting having at least two states (44, 45, 46, 47, 48, 49), in a first state, the selection means can connect the programmable component to a first configuration memory space having a first configuration file, at least when the programmable component seeks to access a configuration file in read mode and, in a second state, the selection means can connect the programmable component to a second configuration memory space having a second configuration file, at least when the programmable component seeks to access a configuration file in read mode; and - watchdog means having an input able to receive the inhibition signal sent by the programmable component and an output able to send, when no inhibition signal has been received for a predetermined period of time, a configuration signal intended for the programmable component to command the reconfiguration thereof and for the selection means to modify the state thereof. - a programmable component capable of managing its own configuration, from a configuration file, having an output able to send an inhibiting signal upon successful configuration of the programmable component and an input (CONFIG) able to receive a reconfiguration signal; - a circuit for the automatic burn-in of the configuration of the programmable component, having: - means for selecting having at least two states (44, 45, 46, 47, 48, 49), in a first state, the selection means can connect the programmable component to a first configuration memory space having a first configuration file, at least when the programmable component seeks to access a configuration file in read mode and, in a second state, the selection means can connect the programmable component to a second configuration memory space having a second configuration file, at least when the programmable component seeks to access a configuration file in read mode; and - watchdog means having an input able to receive the inhibition signal sent by the programmable component and an output able to send, when no inhibition signal has been received for a predetermined period of time, a configuration signal intended for the programmable component to command the reconfiguration thereof and for the selection means to modify the state thereof. - means for selecting having at least two states (44, 45, 46, 47, 48, 49), in a first state, the selection means can connect the programmable component to a first configuration memory space having a first configuration file, at least when the programmable component seeks to access a configuration file in read mode and, in a second state, the selection means can connect the programmable component to a second configuration memory space having a second configuration file, at least when the programmable component seeks to access a configuration file in read mode; and - watchdog means having an input able to receive the inhibition signal sent by the programmable component and an output able to send, when no inhibition signal has been received for a predetermined period of time, a configuration signal intended for the programmable component to command the reconfiguration thereof and for the selection means to modify the state thereof.
