Description
About the 6ES7954-8LE03-0AA0
About the 6ES7954-8LE03-0AA0
The Siemens SIMATIC S7 memory card 6ES7954-8LE03-0AA0 is a 12 Mbyte, 3.3V Flash-EPROM card compatible with SIMATIC S7-1200/S7-1500 CPUs and SINAMICS drives, rated for a minimum 500,000 write/erase cycles. Data retention is at least 10 years when fewer than 50,000 write cycles have been used, dropping to 1 year past 450,000 cycles.
Selection Notes
This is a Flash-EPROM card, not RAM — program and data content survive power loss without a buffer battery, unlike the RAM cards used on S7-400 CPUs. Its data retention drops from 10 years to 1 year once the card has logged more than 450,000 of its rated 500,000 write/erase cycles, which matters for applications that write recipe or data-log blocks to the card frequently rather than storing the user program just once.
Applications
Used as the program/data memory card for SIMATIC S7-1200 and S7-1500 CPUs, and for SINAMICS drives that take the same 3.3V flash card format.
