Antifuse-FPGAs for the Track-Sorter-Master of the CMS Muon Barrel Drift Tubes: Design Issues and Irradiation Test

The Track Sorter Master (TSM) is an element of the on-chamber trigger electronics of the Muon Barrel Drift Tubes of the CMS experiment. We describe how the stringent requirements on the TSM can be met with an architecture that makes use of three antifuse-FPGAs. The devices (Actel A54SX), tested with a 59 Mev proton beam, show a radiation tolerant behaviour; we calculate a Single-Event-Upset cross-section upper limit (at 90% c.l.) of <2.9/10^12 cm2 per A54SX32 chip.
