It is possible to use S25FL256SDP flash memory in SDR mode?

Hello,

In S25FL256 datasheet, speed option DP is  66 MHz DDR.

Does it mean that this memory only can work in DDR mode?

Can it work in SDR mode?

Many thanks and regards

Hello,

Thank you for contacting Infineon Technologies.

Yes, the S25FL256S can operate in SDR and is the default setting at power up, as well as support Clock mode 0 and Clock mode 1.  Please refer to page 4, table 1 within the S25FL256S datasheet.

Hi Albert, many thanks for your response.

Then I understand that every model of S25FL256 can work in SDR mode.

S25FL256SDP can work in SDR mode, what it makes different from S25FL256SAG? Can S25FL256SDP  perform DDR commands and S25FL256SAG can not? 

Many thanks

Hello,

I do not quite understand your question, as the default setting for the S25FL256S from the factory is 'serial' as detailed directly below, regardless of speed grade:
