Nor Flash Forum Discussions

Hi,

I bought Nor Flash (S25FL128SAGMFI013) from market which falled under Cypress. However, the body marking is SPANSION.

Can help to provide me with any official statement or letter to confirm the merger between Spansion & Cypress before Infineon acquisition?

Is there a problem if one sector is being erased while another sector (not being erased) is being
　Is there any problem if a sector is being erased while another sector (not being erased) is being read?
　Are there any restrictions on accessing FLASH while erasing a sector?

Can you help to check the marking rule for S70GL02GS11FHI010?

Which one is correct one for below picture?

I have a new design that is using the Cyclone 10 GX INTEL FPGA and I found in the IINTEL documentation that the S25FL256S FLASH Memory is directly supported. There is no selection in the Quartus Prime Pro software other than following their flowchart programming. Does someone have the exact entries for the flowchart programming or is there a patch to add to Quartus to directly create a .jic and .rpd file that the Quartus programming using the USB ByteBlaster will work?

Thanks.

Hi Sir, We just purchased S29GL128S90TFI020 from a franchised source, but found that the soldering wires were broken.

Can you look at the help to see if it's working? CAN use? How does it happen, thanks!

We are using S25FLS QSPI flash on our board. Some of the ICs are responding on single data line like SPI flash and some ICs are responding on 4 data lines.

We are unable to understand the reason. It is supposed to be QSPI flash by default.

Hello,

Is there any Infineon product that can be used to replace obsolete p/n S29XS256RABBHW003?  The replacement part does not need to be footprint-compatible.  We are attempting to support a legacy product with a very low-risk re-spin, so we can design in a new part.  It just needs to provide the same function, in general, as the original part, with minimal software impact.

It looks like p/n S26KS512SDPBHI02 may be an option, although it has an 8-bit bus instead of 16.  The microprocessor can support 8-bit memory width.  So this may still be an option.

Additionally, one of our software engineers suggested it may be worth exploring the possibility of using 2, 8-bit wide parts in parallel.  Is that a feasible solution?

Any guidance and / or replacement part suggestions are greatly appreciated.

Thank you,

Paul W.
