Hi Leon,

Thank you for contacting Cypress Semiconductor.

Upon going through the datasheet of MX25R6435FZNIL0 (https://www.macronix.com/Lists/Datasheet/Attachments/7428/MX25R6435F,%20Wide%20Range,%2064Mb,%20v1.4... ) I see it has option for Vcc = 1.65V to 3.6V. Please correct me if I am wrong.

Cypress has Serial NOR Flash devices both in Vcc = 2.7V to 3.6V range and Vcc = 1.7V to 2.0V range. Could you please let me know the operating voltage range of your application?

S25FL064L SPI Flash Memory works in Vcc = 2.7V to 3.6V range.
