PRODUCT DESCRIPTION
6ES7954-8LL03-0AA0 256 MB SIMATIC Memory Card
Siemens 6ES7954-8LL03-0AA0 is a 256 MB SIMATIC Memory Card for the S7-1X00 controller platform. It uses Flash EPROM technology with a 3.3 V operating rating and provides nonvolatile storage in the controller-compatible card format.
The specified minimum write/delete endurance is 200000 cycles. Data retention depends on prior use: the data sheet states 10 years below 20000 write/delete cycles and one year above 180000 cycles. These separate limits describe endurance and retention, rather than an unlimited service life or a fixed replacement interval.

SYSTEM INTEGRATION
Integrate 6ES7954-8LL03-0AA0 within SIMATIC S7-1X00
Use the SIMATIC Memory Card in a supported S7-1X00 controller and prepare it through the appropriate Siemens engineering workflow. The 256 MB capacity and complete order code distinguish this card from other capacities and general-purpose removable flash media.
Plan write-intensive functions around the specified minimum 200000 write/delete cycles. Data-retention periods depend on the accumulated cycle count, so an archive written to a heavily used card does not have the same stated retention period as one written below 20000 cycles.
Maintain a separate project backup and the controller-specific file layout. Follow the host CPU instructions for inserting, removing and transferring card contents; the card data sheet alone does not authorize removal while the controller is operating.
Features:
- Memory technology: Flash EPROM
- Capacity: 256 MB
- SIMATIC S7-1X00
Use 6ES7954-8LL03-0AA0 only within the documented SIMATIC S7-1X00 arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace 6ES7954-8LL03-0AA0 within SIMATIC S7-1X00
Record the complete card code and controller model before replacing 6ES7954-8LL03-0AA0. Preserve the current project and any stored operating data using the host controller and engineering software procedures.
Handle the card under the controller-specific power and operating-state instructions. Use the correct SIMATIC card type and avoid substituting ordinary flash media solely because the physical format appears similar.
Load the intended project, confirm the controller recognizes the replacement card and check the retained configuration. Keep the prior card and backup identifiable until the controller has passed its normal restart and data checks.
Features:
- 6ES7954-8LL03-0AA0 complete order code
- Retention above 180000 cycles: 1 year
- Retain the documented SIMATIC S7-1X00 connection arrangement
Use 6ES7954-8LL03-0AA0 only within the documented SIMATIC S7-1X00 arrangement and applicable installation instructions.
