Overview
- Use a device that explicitly supports SIMATIC Micro Memory Cards; the C7-636 lists this 64 KB article.
- Keep the correct STEP 7 project available and allow free space for archived project data as well as load-memory blocks.
- For IM151 CPU service, stop execution and ensure that no PG write operation is active before removing the card.
- Use the chamfered corner to align the card and engage it gently in the module receptacle.
- Preserve the SIMATIC card structure by using the supported SIMATIC formatting workflow.
6ES7953-8LF11-0AA0 SIMATIC S7 64KB Micro Memory Card
A 64 KB, 3.3 V NFLASH Micro Memory Card for supported SIMATIC systems, including program storage in the C7-636 and compatible ET 200S applications.

Product Overview
6ES7953-8LF11-0AA0 is a 64 KB SIMATIC Micro Memory Card using 3.3 V NFLASH storage for compatible S7-300, C7 and ET 200S applications.
For the C7-636, the card holds the STEP 7 CPU user program and must be installed for operation; in supported CPU applications, the same removable medium can carry program blocks, recipes and project archives within its capacity.
Key Functions
Provide the C7-636 program medium
The C7-636 requires an inserted Micro Memory Card containing the CPU user program created with STEP 7.
Carry archived engineering data
Supported IM151 CPU memory functions can save compressed project data to the card and retrieve it through SIMATIC Manager.
Identify the installed medium
An internal card serial number can be read by supported SIMATIC system functions and used by the application for MMC copy protection.

Frequently Asked Questions
Does a C7-636 run without 6ES7953-8LF11-0AA0 or another supported MMC installed?
The C7-636 requires a supported Micro Memory Card containing its STEP 7 CPU user program for operation.
Can I archive my engineering project as well as the user program on 6ES7953-8LF11-0AA0?
Supported SIMATIC Manager project-save functions use the card for compressed project data, provided enough free memory remains alongside the user program.
Is it safe to format 6ES7953-8LF11-0AA0 with Windows before commissioning?
Windows or third-party formatting overwrites the SIMATIC internal structure and can make the card unusable in SIMATIC devices.
How can my CPU program identify the individual 6ES7953-8LF11-0AA0 card?
The internal serial number is available through SFC 51 RDSYSST using SSL partial list 011CH at index 8 in the supported CPU application.
What engineering access is needed to prepare 6ES7953-8LF11-0AA0 for a C7-636?
Use a PG or PC with the required STEP 7 environment and MPI connection or suitable MMC read/write access to create and transfer the CPU program.
Will recipe archives on 6ES7953-8LF11-0AA0 consume the same space as the program?
User programs, archives, recipes and saved project data occupy the available memory of the same card.
How should I plan frequent recipe writes to 6ES7953-8LF11-0AA0?
Keep the cumulative delete/write count within 100,000 operations at ambient temperatures up to 60 °C.
