- Description
The Siemens 6ES7954-8LT04-0AA0 is a 32 GB SIMATIC memory card for S7-1x00 CPUs, built on 3.3 V Flash-EPROM with a rated minimum of 100,000 write/delete cycles. It retains stored data for 10 years when the write/delete count stays under 10,000 cycles (1 year if it exceeds 90,000), and measures 24 x 32 x 2.1 mm.

Selection Notes
32 GB is the largest capacity in this card family, sized for CPUs running large program blocks, recipe data, or continuous data logging that exceeds a smaller card's headroom. Endurance is rated at 100,000 write cycles minimum; applications with frequent online changes or heavy data-logging routines should weigh that against the 10,000-cycle point where guaranteed retention drops from 10 years to 1 year.
Applications
Program, configuration, and data storage for SIMATIC S7-1x00 CPUs, including firmware transfer and recipe or data-log archiving between controllers.
