Nor Flash Forum Discussions
Hi,
I didn't find any data sheet for the CB867 80050 NOR flash chip. 8pins on each side.
What pins do I have to short to reset/erase the memory?
Thank you,
Rossi
Show LessHI,
We would like to confirm something about the S28HL256T page program.
We would like to check the conditions for Typ and Max values for tPP in S28HL256T Datasheet (002-18216 Rev. *Y) p126.
Could you please provide the operating clock, transaction mode, and SDR/DDR conditions for Typical and Max tPP values?
We would like to check on the time required to write 1 WORD of data.
For example, even if only 1 WORD is written with the page program command, does it take tPP2175us (see Table 85, 256B page program in 4KB sector area) to complete writing?
Best Regards,
Kumada
Show LessWould you be able to provide the floor life of the parts or the amount of
time we have to do the inspection before a bake out is required for P/N S25FS128SAGMFI100
I referenced J-STD-033 and the floor life for level 3 moisture sensitive
part is 168 hours. Is that the case with these parts?
Thank you.
Show LessI am attempting to read the configuration registers, particularly CFGR2, since I want to program my number of latency cycles, and would like to read the register after programming to confirm that the register was programmed correctly.
I am using 0x65 CMC to read the register, followed by 0x00000003, and then immediately start reading the output. From the spec, I think I should see 0x08 from the register, but I'm getting all 0's.
I did see something about needing latency cycles, but I'm testing at 10MHz right now, which, from the spec, seems that I would need 0 latency cycles.
Also, on this device, my DLP is programmed to 0xFF, so from my understanding, if the read command used the DLP for latency, yes, I would see all 0's for the first 8 output bits, but then I tried reading 16 bits out, and they were still all 0.
Are there any other tricks to reading config registers?
Thanks!

Hello Support,
My device model is FS01GSAIF01, and I am using the WRAR command to change the QUAD_NV(Bit1) of CR1NV, it is found that the bit is always 0; I don't know where the problem is. My workflow is:
- Send the 06h (WREN) command to enable write enable
- Send the B7h (4BAM) command to enter the four byte address mode
- Send the 71h (WRAR) command for writing registers
- Send register address 0x00000002
- Send data to be written 0x02
Additionally, the controller I am using is cadence Flash QSPI Controller IP.Is this the correct operation?
Best Regards

Hello,
I have three boards containing S28HS512TGABHI01 OSPI (connected to TI DRA821 SOC) that were working but not have failed. The boards OSPI were all programmed with UBOOT and VxWorks OS images. These boards were working, but when we tried to patch driver and reload the new image, the OSPI stopped responding.
When I troubleshoot these three boards, I see DRA821 SOC sending read command 0x03 out to OSPI at power up (1S-1S-1S mode), but the OSPI does not respond to it.
On a working board, I see OSPI first responding to couple of 0x03 read commands and then to 0x9F command. Then OSPI responds to 0x9F command correctly on the working board.
I have checked the power rails, reset signal, clock, chip select, and DQs. I don't see it to be a power rail or timing issue at this point. The DQs square waves don't look noisy.
I am sending the failed boards for A-B-A swap check and X-ray imaging. Is there anything Infineon can do to help debug this issue?
Is there a known problem of corruption with S28HS512TGABHI01 OSPI? What can I do if the OSPI is not responding to U-BOOT 'sf probe' command?
Show LessHello,
Digi-Key and other distributors have S25FL512SAGBHIS10 and S25FL512SAGBHIY10 listed on their websites. Are the model numbers S and Y not documented in the datasheet or is it a mistake on the distributors' websites? If the former, where can I find the information about meaning of these model numbers.
Thanks,

As of now we are working on the pre-design stage of Access Point. As part of that we are planning to use NOR flash in our project. So please recommend an 4MB NOR flash to us.
Show LessDear Sir or Madam,
I am using S25FL512SAGMFI01(0/1/3) in our product.
Please provide RoHS Certificate(2011/65/EU, (EU)2015/863) for S25FL512SAGMFI01(0/1/3).
Thanks.
