ABSTRACT:
A programmable fuse for a projectile is supplied with voltage during the programming phase by rectifying the inductively transmitted program information. The program information is laid down via a microprocessor (U3) within a non-volatile memory (U4). With the created supply voltage a capacitor C1 is charged. This capacitor is discharged by means of a resistor (R3) and a gate (U2A) into an input (PAO) of the microprocessor (U3). The program information of the non-volatile memory (U4) only can be read only in the event where at launching of the fuse and at activating of a battery (U.sub.B), the predetermined input (PAO) of the microprocessor (U3) shows a predetermined potential ("0").
