Abstract: SRAM type FPGA is widely used in aerospace field. In order to solve the single event upset (SEU) problem of FPGA in the space environment and meet the requirements of space application, a low-cost antiradiation solution is proposed, and the radiation resistant FPGA devices are designed to resist single event upset (SEU). This solution is compatible with a variety of FPAG chips, reads configuration data from 3 SPI FLASH, configures FPGA through a serial interface, and periodically refreshes the chip according to the set time after configuration is completed, which can meet the radiation-resistant FPGA in the aerospace field use requirements.
