The application fields of space camera have extended from earth surveying to planet exploration.As a resulthigher demands are put forward on antiradiation abilityweightpower dissipation and reliability.A space camera controller was designedin which radiationtolerant FPGA RT54SX72S and TSC695F.RT54SX72S were used to realize camera control functions such as row period signals generationOC instruction latchaddress decodingand A/D conversion control latch.In this waythe reliability of the system could be improvedand the weightcubage and power dissipation could be reduced.Realization methods of each module in FPGA and partial VHDL sources were presented.Results of experiments indicated that realization methods of each module were correct and feasibleand the camera controller worked reliablywhich could meet the demand of qualification.
