Application
The SMCS332SpW can be used for single board systems where standardised high speed interfaces are needed. Even "non-
intelligent" modules such as A/D-converter or sensor interfaces can be assembled with the SMCS332SpW because of the
"control by link" feature. The complete control of the SMCS332SpW can be done via link from a central controller-node.
The SMCS332SpW is a very high speed, scalable link-interface chip with fault tolerance features. The initial exploitation is
for use in multi-processor systems where the standardization or the high speed of the links is an important issue and where
reliability is a requirement. Further application examples are heterogeneous systems (as shown in Figure 2) or modules
without any communication features as special image compression chips, certain signal processors (ADSP21020, MC56000),
application specific programmable logic or mass memory.
Heterogeneous Systems. These systems are often used for applications where different kind of tasks are to be processed.
Figure 2 below shows an application with multiple processing modules using the SMCS332SpW for interprocessor
communication.

SMCS332SpW connected with the old SMCS332
The new ECSS-E-50-12A SpaceWire standard, used by the SMCS332SpW and the IEEE-1355 standard used by the old
SMCS332 are compatible, however the old SMCS332 has a slightly different startup behavior, the SMCS332 must be
started first on a link connecting with the SMCS332SpW.
