The Siemens 6ES7954-8LP01-0AA0 is a spare-part Flash-EPROM memory card for SIMATIC S7-1x00 CPUs, carrying 2 GByte of program and data storage. It is the load memory for the CPU — the card holds the user program, configuration, and firmware, which the CPU copies into its internal RAM at startup. The 3.3 V interface is specific to the S7-1x00 family; it will not seat in older S7-300/400 CPU slots. Rated for a minimum of 100 000 write/delete cycles and a data retention of at least 10 years after the final programming action, this is a production-grade memory module sized for applications that need the full 2 GByte capacity — large recipe libraries, multi-language operator panels, or firmware-update staging.
