Description
The 6ES7953-8LF11-0AA0 is a 64 KB Micro Memory Card (MMC) for the Siemens SIMATIC S7 programmable logic controller family. It operates at 3.3 V and uses non-volatile flash memory technology. The card is compatible with S7-300 series CPUs, C7 series compact units, and ET 200S IM151 CPU modules.
The MMC stores the PLC user program, configuration data, and system parameters. When installed in the CPU, it enables the controller to retain program content through power cycles without battery backup. The 64 KB capacity is sufficient for basic control programs, small projects, and standard automation tasks typical of S7-300 installations.
The card inserts into the dedicated MMC slot on the front of compatible CPUs. No additional drivers or configuration utilities are required for basic operation; the CPU recognizes the card automatically upon insertion. Program upload and download operations are performed through STEP 7 engineering software via the CPU's MPI/DP or Ethernet interface.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Physical dimensions are approximately 25 mm × 25 mm with a low-profile form factor standard to Siemens MMC specifications. The card weighs approximately 10 to 13 grams. Construction uses industrial-grade flash memory rated for the operating temperature range of the host CPU.
This part number is listed as a spare part and has been discontinued from active production. The 64 KB capacity is the standard entry-level size in the S7-300 MMC product line. For applications requiring larger storage, alternative part numbers in the same series offer 128 KB, 512 KB, 2 MB, and 4 MB capacities.
- Machine Tooling & Packaging: Controls small-to-medium packaging, labeling, and conveyor systems
- Building Automation: Manages localized HVAC, lighting, and pump controls
- Decentralized Peripherals: Stores config/logic for distributed I/O (e.g., ET 200S) in assembly systems
- Water & Wastewater: Drives pump control panels and filtration monitoring networks
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Power off first: Always turn off the power supply of the CPU before inserting or removing the MMC to prevent data corruption or hardware damage.
Correct orientation: Match the beveled corner of the 64 KB Micro Memory Card to the matching shape of the CPU's memory card slot.
Direct push: Insert the card straight into the front slot of the CPU until it clicks or sits flush; no external adapters or card readers are required for the PLC connection

Technical notes
The 6ES7 953-8LF11-0AA0 must only be inserted or removed with the power turned off to ensure correct functionality and prevent data corruption. When used with modern S7-300 CPUs, the 6ES7 953-8LF11-0AA0 serves as the mandatory load memory; during power-down, the CPU automatically copies data from the work memory to the 6ES7 953-8LF11-0AA0, preserving all DB block data without requiring a backup battery.
FAQs
-
Is an MMC mandatory for the S7-300 CPU?
+Yes, many S7-300 CPUs require a Micro Memory Card to operate because they do not have an internal load memory for the user program. -
Can I use a larger memory card size?
+Yes, depending on your CPU's maximum memory limits, you can often upgrade to larger sizes like 128 KB (6ES7953-8LG11-0AA0) or 512 KB (6ES7953-8LJ11-0AA0) if 64 KB is too small for your program. -
What is the 6ES7953-8LF11-0AA0?
+The Siemens 6ES7953-8LF11-0AA0 is a 64 KB Micro Memory Card (MMC) used for SIMATIC S7-300, C7, and ET 200S CPUs. Common questions relate to its specifications, compatibility, and handling. -
What is the storage capacity of this card?
+It features 64 KB of 3.3V non-volatile flash memory (NFLASH)..
