Investigation of the Zynq-7000 Integrated XADC under Proton Irradiation

This paper presents the investigation of the Xilinx Zynq-7000 system on-chip (SoC) integrated analog to digital converter (XADC) for single event effects (SEE) under proton irradiation. The SoC is equipped on a software-defined radio (SDR) that uses the XADC as system-internal current monitoring circuit to initially detect high current events and to prevent destructive damages of the system. The test results showed minor susceptibility to SEEs under proton irradiation up to an energy of 184 MeV. Nevertheless, the configuration of the XADC is crucial to determine SEEs as discussed in this paper.
