It uses Flash-EPROM technology at 3.3 V NFlash, providing 8 Mbyte of non-volatile memory for the controller's operating system, user program, and configuration data. This card plugs directly into the memory-card slot on the CPU module. The 8 Mbyte capacity is enough for medium-complexity applications — think a multi-station assembly cell or a process skid with a few hundred I/O points and moderate data logging. It is not sized for large recipe libraries or extensive trend archives. ## What the memory type means for your program Flash-EPROM means the card retains the program when power is removed — no battery backup needed. The 3.3 V NFlash interface is specific to the S7-300 generation of CPUs; it will not work in older S5 slots or in newer S7-1200/1500 controllers. If you are migrating a legacy S7-300 design, this is the correct memory medium. At 50 g, the card is light and compact, but handle it by the edges — static discharge into the contacts can corrupt the program or damage the Flash cells. Standard ESD precautions apply.","metaTitle":"Siemens 6ES7953-8LP10-0AA0 SIMATIC S7 Micro Memory Card, 8 M","metaDescription":"Siemens 6ES7953-8LP10-0AA0 SIMATIC S7 Micro Memory Card for S7-300/C7/ET 200S IM151 CPUs. 8 Mbyte Flash-EPROM, 3.3 V NFlash.
