Nor Flash Forum Discussions

Hi,

we did a little (big?) mistake in the conception around the serial flash:

on the last serie of cards (hundreds) we forgot to put a pullup resistor on the CS# (ChipSelect#) signal coming from an FPGA.

The Vcc of the Flash rises about 40 ms before the CS# rises, which is contrary to what the datasheet requires (they should rise together with CLK and Data In too)

Still the cards seem to work fine, but i wonder if there is a risk of corruption or anything alike?

Thanks for your help,

best regards,

Jeremy

S29PL064J60BFI070　のTape & Reel品は存在しますか？

Hi all,

I would like to download the low-level drivers for the S70FS01GS SPI flash memory. However when try to do that at the address:

https://www.cypress.com/documentation/software-and-drivers/low-level-driver-spi-flash

I am readdressed to a License Agreement page before I am able to push the download button, and apparently there is no way to accept the conditions and return to the download menu.

Anyone can help me on that?

Thanks,

Stefano

Hi all,

I'm using S25FL127S SPI NOR flash in my project. I read in the datasheet in section 7.6.3 that

" The Status Register 2 OTP bits can be changed using the WRR command with 24 input cycles. "

Does that mean I can change the OTP bits of SR2 back to 0 from 1? Please clarify.

Thanks & Regards,

Vinay

Plz tell me the weight of S29GL02GS12TFSR20?

HI,

There are some question about using the Suspend and Resume Command.

Is it possible to program or erase to another sector during the Suspend command?

When resumed with Resume command,
What is the status of the sector where the program or erase was suspended?

What is the status when the power is turned off while there is a sector where programming or erasing is suspended?

Is it possible to access the sector?

Are there any other points to be aware of besides Suspend Latency (tSL)?

Best Regards,

Hello.

I found the solder mask guide and smt guide of soic(S25FS512SDSMFB010).

Do you have them?

Thanks and Best regards.
