STM RH-ASIC capability JAXA 24 th MicroElectronic Workshop 13 th 14 th October 2011 Prepared by STM Crolles and AeroSpace Unit
Deep Sub Micron (DSM) is strategic for Europe Strategic importance of European DSM access / Support: Scientific satellites and probes require more and more low power RH Computing capability Same trend for Observation satellites Commercial Telecomm satellites progressively move from «listen & retransmit» birds to complex re-programming, signal reconstitution and so on: Computer power needed Business for Telecomm Operators and Satellite makers must strategically not depend from abroad technology sources. European Community (FP-7 Plans) recognized this major risk since 2006 CNES and ESA do technically and financially support this initiative since 2007 RH 65nm STm technology selected in 2009 after successful Reliability and Radiation performance evaluation contracts. European Satellite makers Industry also joined the team STM a 55,000 people advanced technology Company supports European goals This Presentation focuses upon RH, RH Library and Design tools 2
