Description .. The AT7912E provides an interface between a Space Wire link according to the Space Wire Standard ECSS-E-50-12A and several different interfaces. The AT7912E was designed by EADS Astrium in Germany under the name 'SMCS116Sp 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...
