We need to replace MB85RS256TYPNF-GS-BCERE1 , May you help to recommend a Cypress FRAM component , Thank !!
Please check the voltage range.
The voltage range of CY15B256Q-SXET is 2.7V to 3.6V.
I understand the voltage range of MB85RS256TYPNF-GS-BCERE1 is 1.8V to 3.6V.
If your system is used in the voltage range 2.7V～3.6V, CY15B256Q-SXET will be an alternative.
Thanks and regards,
