S25FL256SAGMFIR01 这个型号丝印 FL256SAIFR0 是代表型号 第二行丝印 222QQ037 我想问这些数字还有字母分别代表什么含义 规格书上是没有显示的 能不能官方回复或者发一份正式说明文件给我
I understand that up to 5 regions can be set to long retention or high endurance by the Endurance Flex architecture.
I understand that up to 5 regions can be set to long retention or high endurance by the Endurance Flex architecture.
In my environment
We need to run one backup per day for a minimum of 10 years. For this application, the minimum requirements are 3650 rewrite cycles and 10 years of data retention.
Is there a way to extend the 2-year data retention period for sectors set to high endurance (1 million cycles, 2 years) in the Endurance Flex architecture?
Is there any way to extend the 2-year data retention period?
We ordered S25FL256SAGMFB010 (AG = 133MHz speed)
when they arrived the part is marked “FL256SAVFR0”
Our next order we ordered same S25FL256SAGMFB010 (AG = 133MHz speed)
when they arrived they are marked “FL256SABFRO”
Our FPGA firmware guy tells us he has to modify his firmware because we got the wrong speed FLASH.
Can you explain as we cannot find this AV & AB marking in the data sheet?

Hi
By default in There is no option to set DUAL SDR (1s-2s-2s)configuration in S25HS01GT model.
Could you please tell me how to configure Dual SDR mode .
Thanks

Dear Team
I am using Parallel NOR Flash memory part : S70GL02GS12FHIV20 in our application. we are doing the sector erase before writing a data. Below are my query:
1. we are continuously erasing the 512 sectors one by one, by checking the RD/BY# pin status. we have noticed that same random Sector were not erased properly. This sector address is not fixed address, it is changing randomly. Please confirm the possible reason.
Based on which status either RD/BY# pin status or Status register, Sector erase need to progress. Please confirm.
Also, recommend the suitable methods to use before doing the Sector erase.
Show LessI like to adapt the above device on AN229767 to configure a Intel Cylcone 10-GX FPGA. In table 30, page 59 a list of registers is given. I am missing the actual address to be used for each register when using a WRAR command or even just reading by Read Status Register command. I assume but can not find evidence that the address is:
0: Status Register 1
1: Status Register 2
2: Configuration Register 1
3: Configuration Register 2
4: Configuration Register 3
5: Configuration Register 4
Hello friend
I am using S25FL256L QSPI flash on an Intel Tornado VE FPGA and have scripted for flash programming via JTAG mode in Quartus Programmer. For read ID autodetected as QSPI 256MB flash, the blank check process completed successfully, but failed at the program stage.
Programming fails at about 33% and programming completes. The following error is displayed:
Error (20064): Error status: Status 2 register read returned 0xFF. Does not match the expected data (0x00). Error (19117): Programming failed on flash 1 at address 0X00BB0100. Error (209012): The operation failed."
When reading the status 1 (0x05) and status 2 registers (0x07), the value of address 0x00BB0100 is returned as 0XFF. To write a page in 4-byte addressing mode, use the 0x12 command. For addresses before 0x00BB0100, the error does not occur because the read status 1 register (0x05) and the status 2 register (0x07) were added.
Can you tell me the cause of this error CAN CAN .
Thank you

Show LessHi,
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 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?
