Proposal of low-cost COTS Safety MCU for radiation tolerant controls in CBM detectors — •Jose Antonio Lucio Martinez and Udo Kebschull for the CBM collaboration — Infrastructure and Computer Systems in Data Processing, Goethe University Frankfurt, Germany

Amid general necessity of a robust slow control system for detectors, a DCS board with a cheap COTS MCU conceived for safety critical applications, and that supports conventional RTEMS+EPICS, is being designed for hostile environments. E.g. To operate inside detectors. For this purpose such MCU, which has redundancy features like lockstep run and ECC-SECDED error correction on flash and SRAM internal memories, was tested under radiation condition at the SPS beamtime parasitically to a detector test in CERN. In this preliminary beam-test, RTEMS+EPICS simplifies controls management and in this case supported data acquisition by monitoring the fault registers of the MCU and transmitting them with the ethernet interface, as a backup method the JTAG was used to inspect such registers to confirm the register reads. The results suggest that this is a reliable MCU for hostile conditions.
