Nor Flash Forum Discussions
Hello,
Currently I am using an STM32H7B0 with S26KL512S memory. I have read your documents and your LLD drivers correctly. But I am having trouble writing and reading the Status Register Mode from memory
Memory clock frequency: 60 Mhz
Can you help me to use this flash?
Should it be configured at startup?
Best regard
Show LessWe presently have been using the SpansionFS for the Cypress S25FL064L Chip in our embedded system for a few years now. However, we need to add some additional application features and need more RAM. Are there some features/options within the library we can change to reduce its RAM memory usage? Our application is not threaded and at the most we have only 3 files open at a time. In fact, we rarely need to access the chip.
Thanks,
Bill
Show LessI use S25FL01G when I use normal 1 line read I got real data stored
but when I use Quad commands if data byte has F (1111) NIPPLE then next clock skip reading next nipple like this
if data stored
0F 10 0F 10 ........
it read
0F 00 F0 ..........
problem is confirmed by logic analyser
Show LessDo you need third party programmer support? Infineon works with the major global (Americas, Europe, Asia and Japan) providers of data and programming solutions to qualify our Flash memory devices on their programmers.
Our partners gain early access to our products and are provided dedicated support to ensure reliable programming of the devices.
The Flash product family devices supported by our partners are as follows:
- Parallel NOR family’s: The GL-S (65nm) and GL-T (45nn), Older Parallel NOR family's such as GL-P, PL-J, AL-J and AS-J are supported, but you will need go to Programmer website for details.
- SPI NOR family’s the FL-S (3.0V) and FS-S (1.8V) 65nm Mirrorbit. The FL-L (3.0V) 65ns Floating gate Flash
- HyperFlash family’s KL-S (3.0V) and KS-S (1.8V)
- Semper Flash Family’s Mirrorbit technology at 45nm
a) Quad SPI S25HL-T (3.0V) and S25HS-T (1.8V)
b) Octal Interface S28HL-T (3.0V) and S28HS-T (1.8V)
c) HyperBus Interface S26HL-T (3.0V) and S26HS-T (1.8V)
By going to a third party programmer website device search, you can find details of support for Infineon products on the Manufacturing Part Number (MPN) level.

Hello,
I am looking for for a package drawing for item with part number: S28HS512TGABHI010. Seems like it's not attached in the main datasheet and I can't find it on the website.
Show LessHello !,
I have an old AMD parallel nor Flash that CYPRESS has acquired and it was declared EOL. the p/n is: AM29LV160DB70WCI.
Today CYPRESS recommending S29AL016J70BFI020 as replacement but in the midterm, CYPRESS has produced the S29AL016D70BFI022 which is no longer in production as well.
the main different between AM29LV160DB70WCI and the midterm S29AL016D70BFI022 was the autoselect code with A3 to A2.
this different kept also when CYPRESS has migrated to S29AL016J70BFI020 which also has WP# in pin B3 as an additional H/W feature.
We tried to replace between the original item AM29LV160DB70WCI and the S29AL016J70BFI020 and it failed. we are using online programing (not with programing equipment) through the BUS.
My question for CYPRESS NOR flash experts is what are the requirements in the F/W that has to be done in order to program the new device compare to the previous item.
for example:
1. Will it require a sector unprotection word/byte prior to write command in order to enable the write command ?
2. according to the data sheet the NOR Flash shipping is with unprotect flag. is it possible that the device (S29AL016J70BFI020) are protected by CYPRESS and we don't recognize it ?
3. pin B3 is not connected. since it has an internal pull-up it is enabled permanently. I assuming that this is not the issue.
4. What else could be the problem ? do you have a white paper to advise this migration ?
Thanks !
Show LessHello,
We are currently using S70FL01GSAGMFB010, is there a space-grade (radiation tolerant) version of this part, if not what is the closest available?
Thanks;
Leo
