Abstract
A munition fuze electronic arming and firing controller includes a micropessor and logic network which verify controller operation and provide an enabling signal necessary to arm the fuze. A signal of predetermined duration is twice produced by the microprocessor and is utilized with a clock signal continuously produced in the logic network to cause a counter to count during two separate periods. The resulting counter count is checked by verifying logic which outputs a signal only if the count is a predetermined count after each counting period. If the counter output is twice verified and an energy storage component external to the controller is charged to less than a predetermined minimum the logic network outputs an enabling signal which triggers the microprocessor to produce drive signals utilized to arm the fuze by charging the energy storage device. User selected inputs and firing sensor initiated inputs initiate munition detonation at a predetermined time and under predetermined conditions.
