Functions

Nonvolatile storage

The SIMATIC Memory Card provides 256 MB of flash memory for compatible SIMATIC S7-1x00 CPU program and project storage.

Controller operation

The card serves as removable load memory for supported controllers and retains its stored data without controller operating power.

Lifecycle selection

6ES7954-8LL03-0AA0 is a spare-part or phase-out product; Siemens identifies 6ES7954-8LL04-0AA0 as its successor.

Interfaces

Card characteristics

The card uses flash technology, has a rated voltage of 3.3 V and provides 256 MB capacity.

Controller compatibility

Use is specified for compatible SIMATIC S7-1x00 CPUs. Confirm the target CPU, engineering project and firmware requirements before installation.

Order-number control

Keep the complete order number 6ES7954-8LL03-0AA0 distinct from the successor 6ES7954-8LL04-0AA0 during procurement and replacement.

Installation

Physical installation

The card measures 24 x 32 x 2.1 mm and weighs approximately 3 g. Insert it only in the specified orientation for the target controller.

Handling procedure

Follow the controller instructions for power-down or card exchange and avoid touching exposed electrical contacts.

Project verification

Before operation, verify that the CPU supports the 256 MB card and that the stored project matches the intended controller and firmware.

Environment

Electrostatic protection

Handle the flash card using appropriate electrostatic-discharge precautions and avoid direct contact with its electrical contacts.

Physical protection

Protect the card from moisture, contamination and mechanical damage during storage, transport and installation.

Traceability

Retain the original Siemens label and complete 6ES7954-8LL03-0AA0 order number so the installed spare part can be identified correctly.

FAQ

Q1. How can the exact quoted memory card be verified?

Check the complete order number 6ES7954-8LL03-0AA0 on the label and confirm 256 MB capacity, 3.3 V rating and 24 x 32 x 2.1 mm dimensions.

Q2. How can New, Used or Refurbished condition be distinguished?

Request close-up photos of the label, contact area, card edges and packaging. Scratches, worn contacts or altered labels should be clarified in writing.

Q3. How can a supplier be checked before purchase?

Confirm legal company details, traceable contact information and experience supplying Siemens memory media; the quotation and invoice should identify the full order number.

Q4. Which specifications should an engineer confirm?

Confirm the target S7-1x00 CPU, supported card capacity, project and firmware requirements, 3.3 V card type and planned program-storage needs.

Q5. What evidence should be requested before payment?

Ask for dated photos showing the front and rear label, clean contacts, sealed or protected packaging and a written confirmation of capacity and condition.

Q6. Can a similar card or suffix replace this model?

Do not substitute solely by appearance. Capacity, generation and lifecycle status may differ; even the listed successor 6ES7954-8LL04-0AA0 should be approved against the CPU and project requirements.
