Nor Flash Forum Discussions
Hi,
Our project is using S28HS02GT, I see that the dataset has the feature of password protection. But, I don't know how to program the password. I scanned the document but did not have any info about it except the password must be programmed before using.
So, Is this feature support for our nor flash? Or is there any chapter or document that I missed?
I hope to have your support!
Thank you,
Show LessI'm currently investigating the S70FL01GSAG 1Gb device as a replacement for the S25FL512S 512Mb device due to a larger flash capacity requirement. While trying to compare the two datasheets, it seems the S70FL01GSAG does not include much information regarding the device registers. Does the register information for S70FL01GSAG, similar to what is shown in the S25FL512S datasheet, exist anywhere and if so can someone provide me with it?
Show LessHello team,
we are currently using an S29JL032J parallel NOR flash in one of our product which stop responding sometimes and goes to erroneous condition. we are currently using the Keil RL Filesystem library files to communicate with NOR flash using LPC2468 controllers with which seems to have no issue, some times reported from the field NOR Flash is completely not responding to even finit() function call by File system API.
We are also looking for a contact information to whom to initiate RCA report for defected IC's.
Thank you,

Show LessA member from Infineon posted me a zip file regarding drivers for S25FL256FL and just posted the zip and went away named @Apurva_S . He himself marked the post as closed while not even allowing me for counter questions.
In the same stack that he posted he has included a file :- slld_fll_256l.h
I searched in the whole zip file for a file of that name but could not find it. I also wanted to ask whether this driver can work with the QSPI interface or drivers. Or is there a separate driver for that. But before I could ask the post was marked as answered !!! Please answer my queries give me the mentioned .h file and then wait for me to respond before closing the topic.
Show LessHello,
I have custom-designed a PCB that incorporates an MCU board and a Nor Flash, specifically the S25FL512SAGMFMR10 part. Currently, I am developing a bootloader utilizing this Nor Flash.
I intend to use a specific region of the flash (for example, sector 0) to store a footer. My requirement is to update variables located within this footer. However, I understand that updating the footer necessitates erasing the sector, which is not ideal for my application.
Could you please advise if there is an alternative method to erase or overwrite data in the Nor Flash without performing a sector erase? Any suggestions or techniques that could facilitate this process would be greatly appreciated.
Best regards,
Show LessHi Dear Authorized,
I am trying to use HyperFLASH over FlexSPI Interface over HyperBUS and some errors occured during test on my custom board which suited by NXP IMXRT1064 MCU. After some research, I learned that LUT Instraction Set is required for LUT Installation to use FlexSPI. Therefore, I need LUT Instraction Set for S26KS512SDABHV030. For example, there are some memories which is used by NXP Users for IMX MCUs like below. Their datasheets contains Instruction Set Table but I can't find for my product.
Here is my test link which research the solution for Custom Board: https://community.nxp.com/t5/i-MX-RT/IMXRT1064-HyperFlash-via-FlexSPI/m-p/1763855
Could you please help me?

We are conducting a changeover and evaluation test to FLASH (③) of the same manufacturer as a replacement for Infineon's FLASH (① and ② below).
We are conducting evaluation tests and switching to (3) FLASH of the same manufacturer as a replacement for Infineon's FLASH in (1) and (2) below.
We are now conducting evaluation tests using the same manufacturer's FLASH (③) as a replacement for Infineon's FLASH (①) and (②).
(2) S29AL032D70TFI030# (3) S29JL032D70TFI030#
S29JL032J70TFI010# ←Substitution
◆Questions
When ERASE and WRITE operation time is actually measured at (3)
the maximum time required is about 1.5 times longer than (1) and (2).
(READ time is the same). (READ time is the same).
(READ time is the same.) →Write is performed after ERASE of each Sector.
Based on the above, we are currently planning to replace (3) FLASH,
We would like to know if you can give us your technical opinion on the reason why the ERASE and WRITE times are longer for (3) FLASH compared to (1) and (2) FLASH.
Can you give us your technical opinion on the reason why the ERASE and WRITE times are longer for (3) FLASH compared to (1) and (2)?
