Overview
- The C7-635 accessory list identifies the 64 KB LF00 card for supported S7-300, C7 and ET 200S IM151 CPU use.
- Ensure the target CPU’s load-memory requirement and additional archive size fit within 64 KB.
- In IM151-7 CPU service, use STOP and prevent PG writes before removal; do not interrupt an active write operation.
- Insert the card using the beveled-edge orientation and the receptacle ejector arrangement.
- Keep normal CPU memory reset separate from formatting, which is used only when the card content or format requires recovery.

Product Overview
6ES7953-8LF00-0AA0 is the 64 KB, 3.3 V NFLASH Micro Memory Card listed for supported S7-300, C7 and ET 200S IM151 CPU applications.
The card acts as nonvolatile load memory and a portable storage medium, so correct project content, available capacity and controlled replacement are central to maintaining the installed CPU application.
Key Functions
Supply program content to work memory
In the IM151-7 CPU, a normal memory reset reloads the sequence-related program content from the card into CPU work memory.
Replace the complete stored application
Downloading an entire user program through the supported CPU workflow deletes the previous card contents before loading the new program.
Support controlled machine service
The IM151 CPU card receptacle uses an ejector, and the beveled card edge provides an orientation reference for insertion.

Frequently Asked Questions
Will a normal IM151-7 CPU memory reset erase the application on 6ES7953-8LF00-0AA0?
A normal memory reset reloads the sequence-related program content from the card into work memory while retaining the valid card contents.
What happens to the old project when I download a complete new program to 6ES7953-8LF00-0AA0?
A complete user-program download deletes the previous card contents before storing the new application.
Which checks matter before removing 6ES7953-8LF00-0AA0 from an IM151-7 CPU?
Place the CPU in STOP and ensure no PG write function is active, interrupting the communication connection if that cannot be guaranteed.
How do I seat 6ES7953-8LF00-0AA0 in the IM151-7 CPU receptacle?
Point the beveled edge toward the ejector and press the card gently into the receptacle until it engages.
Why can changing 6ES7953-8LF00-0AA0 lead to an automatic memory reset after power-up?
The IM151-7 CPU detects a replacement card or changed card content and automatically performs a memory reset after power-on.
Can I keep an entire STEP 7 project on 6ES7953-8LF00-0AA0 for later retrieval?
The supported save-project function stores compressed project data on the card when enough capacity remains for both the user program and the archive.
Why must I check the machine project before inserting 6ES7953-8LF00-0AA0 into another CPU?
The inserted card must contain the correct user program for the target machine because the CPU loads its application from that medium.
