AT7911E pdf
1. Description
The AT7911E provides an interface between three SpaceWire links according to the SpaceWire
standard ECSS-E-50-12A specification and a data processing node consisting of a Control Pro-
cessing Unit and a communication data memory.
The AT7911E was designed by EADS Astrium in Germany under the name 'SMCS332SpW" for
"Scalable Multi-channel Communication Subsystem for SpaceWire". It is manufactured using
the SEU hardened cell library from Atmel MG2RT CMOS 0.5µm radiation tolerant sea of gates
For any technical question relative to the functionality of the AT7911E please contact Atmel
technical support at
This document shall be read in conjunction with EADS Astrium 'SMCS332SpW User Manual'.
The complete user manual of the AT7911E also called SMCS332SpW is available at
The AT7911E provides hardware supported execution of the major parts of the interprocessor
communication protocol, particularly:
• Transfer of data between two nodes of a multi-processor system with minimal host CPU
• Execution of simple commands to provide basic features for system control functions
• Provision of fault tolerant features.
Target applications are heterogeneous multi-processor systems supported by scalable inter-
faces including the little/big endian byte swapping. The AT7911E connects modules with
different processors (e.g. TSC695F, AT697E and others). Any kind of network topology could be
realized through the high speed point-to-point SpaceWire links (see the section ‘Applications’).
It can also be used for modules without any communication features such as special image com-
pression chips, some signal processors, application specific programmable logic or mass
The AT7911E may also be used in single board systems where standardised high speed inter-
faces are needed and systems containing "non-intelligent" modules such as A/D-converter or
sensor interfaces which can be assembled with the AT7911E thanks to the "control by link"
