It supports a minimum of 500,000 write\/delete cycles and retains data for 10 years when the cycle count stays under 50,000, dropping to 1 year once cycles exceed 450,000. The card measures 24 x 32 x 2.1 mm and weighs 3 grams, sized as a drop-in spare part for S7-1200 CPU slots.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6ES7954-8LC03-0AA0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-1200 \/ SINAMICS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMemory Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFlash-EPROM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMemory Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 MB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMin.
