Hello, Philip,
The S25FL512SAGxx as well as the S70FL01GSAGxx (65nM MirrorBit) are active Ordering Part Numbers
(OPN’s) and are currently in production.
In regards to the S25FL256LAGxx (65nM Floating Gate), this is the highest memory density, currently available.
The 512Mb and 1Gb memory density are not currently, available.
Do you have a more specific Ordering Part Number (OPN) Suffix for the S25FL512SAGxx and S70FL01GSAGxx?
Best regards,
Albert
Show LessQuestion regarding S25FL128S/S25FL256S flash devices with both VIO and VCC, and the treatment of CS#. The datasheet says that CS# must be pulled high during power up, ideally tracking VCC. But if VIO is at a lower voltage than VCC, (say VIO = 1V8) then wouldn’t pulling CS up to VCC violate the allowable VINH?
Suppose CS is pulled up to VIO, but VIO is powered up at a later time than VCC (say at some time after tpu) :. CS# does not follow VCC; will asserting RESET# after VIO comes up ensure that the device is properly initialized?
Show LessHi Team,
Has Cypress S25FL512SAGMFMG10 been evaluated for Cycled HTOL(Erase cycle + HTOL) and Cycled RTOL(Erase cycle + RTOL) as defined in AEC-Q100-005?
If the evaluation has been performed, please provide the evaluation result data.
Thanks and tregards,

We have run into issues in the past when accessing the devices using 1-1-4 based reads and writes. Cypress has a pullup on IO3 that is used to disable the HOLD# feature when in x1 mode but how strong is this pullup?
Our controller leaves IO2 and IO3 tristate when driving the command and address so if the previous read or write drives IO3 low, it depends on the pullup to reach an active high state.
Is there an alternate way to disable this feature?
Show LessThe ZYNQ 7000 only list compatibility with the S25FL-S part.
- Is the S25FL-L functionally compatible to the S25FL-S?
- Is there a pin equivalent part that I can migrate the S25FL256LAGNFM010 to the S25FL-S family?
Dear Cypress Experts,
I have several questions in the ASP PPB, please help have a check, thanks!
Question 1: Why can not program the PPB even when the PPBL Lock is 1

Show LessI'm looking for an IBIS model for the S70GL02GT12FHBV13 that supports 1.8V I/O operation. I found two models at this link http://https://www.cypress.com/search/all/S70GL02gt?sort_by=changed&f%5B0%5D=meta_type%3Asoftware_tools ,but they only support 3V (3.3V?) I/O. I used that model for simulating the address and control inputs (driven by a 1.8V driver), though I'm not sure the results are correct. However it does not help trying to simulate the S70GL02 driving the data bus. Is there another similar model that supports 1.8V operation that might be close?
Show LessHello,
We would like to use S70FL01GSAGMFI013 spi flash memory and interface it with a mcu. However we are really new with flash memories and we would like to ask if there is any driver (C code with functions how to read and write this flash memory) for spi S70FL01GSAGMFI013 flash.
We have by the way noticed that on the website there is a zip folder provided called "Low Level Driver for SPI Flash" , but since we are really new with flash memories we don't really know if this driver could be used for the S70FL01GSAGMFI013 flash and which functions to use. Any help would be appriciated.
Thank you.
Regards,
Mike
