Description .. The AT7911E provides an interface between three Space Wire links according to the Space Wire standard ECSS-E-50-12A specification and a data processing node consisting of a Control Processing Unit and a munication data memory. The AT7911E was designed by EADS Astrium in Germany under the name 'SMCS332Sp W" for "Scalable Multi-channel munication Subsystem for Space Wire". It is manufactured using the SEU hardened cell library from Atmel MG2RT CMOS 0.5µm radiation tolerant sea of gates technology. For any technical...
