The 512 x 8 organization suits small parameter tables or state-keeping in a single 8-SOIC footprint. ## Temperature grade and automotive qualification AEC-Q100 qualification means it passed the full automotive stress suite — extended temperature cycling, high-temperature operating life, and ESD robustness. That traceability matters for safety-related ECUs or long-life industrial controllers where a field failure means a recall. ## Lifecycle status — obsolete, sourced to order","metaTitle":"Cypress FM25040B-GATR Automotive FRAM, 4Kbit SPI, -40°C to 125°C","metaDescription":"Cypress FM25040B-GATR automotive AEC-Q100 F-RAM, 4Kbit non-volatile FRAM, SPI 14 MHz, 4.5V-5.5V, -40°C to 125°C, 8-SOIC.
