Evaluation of the TSC695F 0,5μm Rad hard V7 Spare processor

摘要

An evaluation of the TSC695F, a space devoted 32-Bit RISC processor manufactured by ATMEL, has been performed. Further to the development phase, this evaluation has consisted in electrical characterisation, physical analysis, endurance and radiation tests in order to assess the specific failure modes and the intrinsic reliability of this product in the space environment. The different tests will show, among others: 1. preservation of functionality and AC/DC parameters within specification limits until 300krads and better (low dose rate irradiation), 2. Low single event sensitivity regarding the space flux of ionised particles 3. Latch-up immunity up to 100MeV/mg/cm~2. 4. No reliability defect found. These results demonstrate the ability of the TSC695F to be used in space applications.
