We are using S25FL064P flash as a code flash with the microcontroller LPC1850 in qspi mode, SPIFI interface. After that we replaced S25FL064P with S25FL256S as we required higher code size. But when we changed flash to S25FL256S from S25FL064P, we found that code executes with half the speed what it was executed in S25FL064P. Checked the SPI clock . In S25FL064P it was about 18MHz while in S25FL256S it was about 11 MHz. Also found that out of 4 data lines I02 & I03 data was not presented in S25FL256S. Has anyone faced this problem ?
Show LessI want to use S25FL512SAGMFI010 as my storage.
But I don't find the S25FL512SAGMFI010's footprint dimension(like below).
Will you support the dimension for me to layout.
Thanks a lot.
hello!
I am trying to erase the chip according to the chip sheet. my program is like the picture which is the same as the sheet example. However, when the erase operation is over, I read the data in a section of address and found that it is not 0xfff. the result is attached on. I don't know what the problem is. I hope you can help me.
Show Lesshello everyone!
I would like to ask how to complete flash self-detection? Or is there a more convincing way to use the detection process in a real project to complete it? For example, S29GL01GP, in the project, should the drivers on the manual (sector erase, chip erase, read and write, etc.) be tested in turn to prove the validity of the chip? That's too inconvenient!
Show Lesshi everyone,
i want to find Source code for programming Parallel NOR Flash (S29GL01GP). Recently, i learn the S29GL01Gp chip according to datasheet. it says that the C source code low level driver can be find in the infineon internet, but i look for it for a long time and not found.
Who can give me the C Source codes which are similar to the datasheet development examples? Thank you!
Show LessSince S29GL01GP13FFIV10 is obsolete do you have a drop in compatible replacement?
I have a custom board with S25FL256S external flash
I try to read in quad mode, it works but the read speed is the same as when I use commands 0x13 (4READ) or 0x0C (4FAST_READ ) or 0x6C (4QOR ) or 0xEC (4QIOR), all give the same read speed.
I measure the time to read one sector of 64KB, and quad mode reading doesn’t seem to speed reading time.
I'm In quad mode, I set configuration register to 0x02 (quad mode enabled).
The data that I read is correct (because the total sum of the data and that’s what I get after reading).
I was hoping quad read commands 4QOR and 4QIOR would be close to 4 times faster
Show LessHi, I have some questions from the customer regarding the S29GL256S10TFV010 and S25FL256SDSMFV010 devices. I would appreciate it if you could help answer or point me towards the correct resources for the following for the two devices:
Thanks in advance,

Show LessHello,
I'm investigating either SEMPER Secure family is certified NIST SP800-193 or not.
If not, please tell me type of other certified NIST .
Please check and answer this.
Best regards,
