Dears.

I’m looking for the QSPI memory which meets the following specification. But I couldn’t find proper cypres PN.

Please give me your recommended part number.

  1. Interface Frequency : 133MHz
  2. Density : 128Mbit or 256MBit
  3. External Reset needed
  4. Interface : QSPI (D0 ~ D3)
  5. Package : WSON 6x5 or FAC024
  6. Operating Voltage : 1.8V

Hi WonjinHan,

Thank you for contacting Cypress Community.

You can use our Product Selector to choose the appropriate part as per your requirements - Product Selector Guide (cypress.com)

As per the mentioned requirements, the most appropriate part for you is S25FS256SAGNFIxxx. You can get the datasheet for S25FS256S device here - S25FS128S/S25FS256S, 1.8 V, Serial Peripheral Interface with Multi-I/O, MirrorBit® Non-Volatile Flas...

Go through the 'Ordering Information' section of the datasheet in order to understand part numbers better.

Hope this answers your question.

Thank you and Regards,

Apurva

Hello Apurva.

Thank you for your turn-around.

I already used to make it filter with Part Selector but it's impossible to do sorting whether it has external Reset Pin or not.

And also reviewd S25FS256SAGNFIxxx part but If I make IO0 ~ IO3 dedicated for QSPI , I can't use external Reset Pin which is hardware-initialized by external controller.

Do you have any recommended part which has independent external Reset Pin not Alternate function ?

Hi WonjinHan,

Unfortunately, we do not have an FS-S flash part with a separate RESET# pin. However, please see this below snip from the datasheet that may be useful for you -
