8 MByte Nflash for S7-300 and ET 200
The Siemens 6ES7953-8LP20-0AA0 is a spare-part Micro Memory Card for the SIMATIC S7 family — specifically the S7-300, C7, and ET 200 distributed I/O systems. It provides 8 MByte of 3.3 V Nflash storage for program and data retention. This is the card you slot into the CPU's memory-card bay before you download the project. It holds the user program, configuration data, and recipe files — no card, no program retention through a power cycle on most S7-300 CPUs.
Availability is confirmed on a quote-to-order basis through independent distribution channels. Submit an RFQ for current pricing and lead time on your BOM quantity.
Compatibility and use
Designed for the SIMATIC S7-300, C7, and ET 200 families — the card slots into the CPU's memory-card bay and is recognized automatically on power-up. No configuration needed beyond inserting it with the correct orientation.
