Cypress doesn't provide serial F-RAM part-numbers working in the -55/+125°C range. The widest range available is the automotive range (-40/+125°C).
Is it something impossible with the F-RAM technology to work at -55°C?
Or would it be possible to have chips working in the -55/+125°C range using an uspscreening process?
Currently, we do not have any F-RAM devices that support operating temperature -55C. There is no limitation for F-RAM technology to support -55C. Please share more details about your requirement, if you want us to support F-RAM devices with operating temperature upto -55C.
Thanks and Regards,
