Abstract
In this paper we report the measurement of the soft-error sensitivity of an ARM Cortex M0 core conducted at the ISIS ChipIR neutron irradiation facility. The test setup also included a CMOS camera sensor used for dosimetry estimation. The results provide the core memory and internal resources cross section thus giving useful information for developing ad-hoc fault tolerant techniques on sensitive parts.
