In my original design NOR flash PN: S25FL064LABMFM010 was installed then I replaced it with PN: S25FL064LABMFI013. I noticed that the device is working 1/2 the original speed. It is not stated in the datasheet that these 2 part numbers should perform differently. Am i missing something?

Hello Tony,
Please verify and confirm the bit settings for QPI CR2V[3], as well as for QUAD CR1V[1] in regards to
the original FLASH memory device 'S25FL064LABMFM010' The bit settings for the QPI CR2V[3], as
well as for QUAD CR1V[1] should be set to the same in regards to the S25FL064LABMFI013.
There may be the possibility that QPI CR2V[3] = 0; and that QUAD CR1V[1] = 1 is set for the S25FL064LABMFM010,
and that the S25FL064LABMFI013 should be set to the same.

Hello Tony,
Thank you for contacting Cypress Semiconductor.
There is/are no differences between the S25FL064LABMFM010 and the S25FL064LABMFI013,
in regards to Form, Fit Function and/or Operation.
- S25FL064LABMFM010 : "M" = Automotive, AEC-Q100 Grade 1 (–40°C to +125°C) / "0" = Tray
- S25FL064LABMFI013 : "I" = Industrial (–40°C to +85°C) / "3" = 13-inch Tape & Reel.
The above features do not have any effect on Form, Fit Function and/or Operation of the S25FL064Lxx.
Please detail from whom the S25FL064LABMFI013 were purchased from . As well, please send a photo
of the topside markings of the S25FL064LABMFI013 device.
Thank you in advance....
Best regards,
