More Information

Overview Manuals Specifications Host Support Memory Use Migration

Features:

  • 64 KB SIMATIC Micro Memory Card
  • 3.3 V NFLASH memory medium
  • Listed for S7-300, C7, and ET 200S IM151 CPU applications
6ES7953-8LF11-0AA0 provides removable memory for the supported SIMATIC host rather than acting as a general-purpose storage card.

A 64 KB card can support device-name storage on the documented IM151-3 PN High Feature, while firmware updating requires at least 2 MB.

Because Siemens has discontinued this ordering number, a replacement review should include host support, project capacity, and the official successor.

The 6ES7953-8LF11-0AA0 may still be available through Apter Power after OEM discontinuation, subject to stock and sourcing confirmation.

Description
Siemens 6ES7953-8LF11-0AA0 is a 3.3 V NFLASH SIMATIC Micro Memory Card with 64 KB capacity. Siemens lists it for S7-300, C7, and ET 200S IM151 CPU applications and records the product as discontinued.

In supported controllers and interface modules, 6ES7953-8LF11-0AA0 provides removable program or device-data storage. Siemens documentation notes that a 64 KB card is sufficient for saving the device name on the IM151-3 PN High Feature, while firmware updates require a card of 2 MB or higher.

Before replacing 6ES7953-8LF11-0AA0, check the host CPU or interface-module manual, required memory capacity, and the successor strategy for the installed project. Insert or remove the card only with power switched off, as specified in the Siemens procedure.

Technical notes
Power off the host before inserting or removing 6ES7953-8LF11-0AA0. Its 64 KB capacity can store an IM151-3 PN High Feature device name, but Siemens requires 2 MB or more for firmware updates; confirm the host module, project size, and discontinued-product successor strategy first.
