Nor Flash Forum Discussions
We have three kinds of NOR flash device with "GL512N10FAI01" ordering part number. All devices that have "821BB437 T" and "0911VVF JJ" product date codes work properly on the card. However, devices which have "824BB509 Q" product date code do not work properly on the same card. If I need to detail the problem, we cannot write/read 8bit of 16bit Data bus of NOR flash. We could send you a sample to investigate it. This wafer lot sequence may be problematic. We need to maintain production. Although we have a lot of this devices, we have stopped the production since the devices became obsolete. Could you help us?
By the way, "0911VVF JJ" fits "YY WW A B C" product date code format in https://www.cypress.com/file/294586/download (page 11) document, but its product year(2009) is not prior to third quarter 2007. There is a conflict in marking format document.
I've been having trouble trying to locate the 3D Model for S25FL128LAGMFM010. Is there anywhere I should look on the Cypress site to find this? I'm mainly looking for a file that would be compatible with Solidworks.
I am designing a circuit that uses S29AL016J70T.
I would like to confirm mass (weight) of S29AL016J70T (TSOP 48pin package).
To protect sector,
After writing 1 with DYB WRITE COMMAND, DYB STATUS is read to perform Verify.
DYB STATUS can be read correctly.
After that, it does not return to READ MODE.
how to return to read mode?
what is the pseudo thermal resistance psi JT of a S25FL064LABNFI013 flash memory?
What is the maximum junction temperature?
Thank you.Show Less
I consider thermal analysis for my circuit using S29AL016J70T (TSOP 48pin package) .
I would like to confirm thermal resistance value of junction to case for S29AL016J70T.
I've downloaded standard code from Cypress page for NOR-Flash programming.
Reconfigured successfully to my Processor which is CY8C6347FMI-BLD53T.
Reconfigured with my modified cymem file for S25FL064L NOR-Flash (see attached and also image below).
Getting all 0xFF on reading.
FAIL: Read data does not match with written data. Read/Write operation failed.
Error Code: 0xFFFFFF01
Please advise what is wrong.
With my other code I was able to read ID and Erase and Read chip in quad mode, but with same outcome. After programming all reading FFs.
Same code running on EV board was able to correctly program S25FL512S memory.
