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,
