Design of an ASIC Chip for Spacecraft Integrated Avionics

It is a trend to put the common spacecraft engineering requirements into one chip, which can miniaturize spacecraft avionics and reduce the repeated work for spacecraft engineers. Based on the analysis of space application requirements, the system design of an ASIC (Application Specific Integrated Circuit) chip for spacecraft telemetry and command system is proposed. Firstly, the chip system architecture is described. Secondly, four key techniques of the ASIC chip design are presented in detail, including design of the chip working modes, design of onchip IP cores, design of reliability, and the design of low power consumption technology. 1553B RT working mode of this ASIC is different and special from other space chips. The system test results based on FPGA show the validity and reliability of the ASIC system design. Finally, some promising applications of the ASIC chip are described.
