The invention discloses a configuration, refreshing and program upgrading integrated system for an SRAM (Static Random Access Memory) type FPGA (Field Programmable Gate Array), belongs to the technical field of aerospace and aims to solve the problem of SEU (Single Event Upset) of the SRAM type FPGA in a spatial irradiation environment. The configuration, refreshing and program upgrading integrated system has a capability of performing program upgrading on the SRAM type FPGA which is in on-orbit work for a long time. The configuration, refreshing and program upgrading integrated system comprises an on-site programmable logic gate array SRAM type FPGA, a comprehensive management anti-fuse FPGA, a configuration program storage chip PROM (Programmable Read-Only Memory), an on-orbit upgrading program storage chip EEPORM (Electrically-Erasable Programmable Read-Only Memory) and an RS422 interface chip. The configuration, refreshing and program upgrading integrated system disclosed by the invention can be used for effectively solving the problem of the SEU of the SRAM type FPGA which is in on-orbit work for a long time and correcting the SEU and single event accumulation inside the SRAM type FPGA without being shut down, also has the function of on-orbit program upgrading of the SRAM type FPGA, and has the characteristics of instantaneity, reliability, flexibility, universality and low cost.
