SMCS 332+SMCS116 upgrade to Spacewire (ECSS-E50-12A)
The first generation of high speed digital links controllers is based on the IEEE1355 standard which was the starting point to
the definition of SpaceWire networks. They are used in very large number of ESA missions. However, the SMCS332 and
SMCS116 devices are not fully compliant with the SpaceWire specification (e.g. they do not support time codes) and are
implementing an initialisation state machine that leads to major operational constraints. Furthermore, they suffer from several
design anomalies, discovered by first Users but today well characterised (e.g. w.r.t to interfaces in some sub-modes).
Considering the situation, it required to upgrade the SMCS332 and SMCS116 to full SpaceWire compliance. This will allow as
well to correct the identified anomalies and to secure the availability of such devices by producing them on a more recent
silicon process (e.g. migrating from MG1RT to MG2RT). An extensive validation campaign is included in the proposed activity.
