Hello.

I'm using the S25FL256S with EFM32GG11 of Silicon Labs.

And I have a sample code for 'MX25L25635F'.

I have tried to set to Quad mode.

But I couldn't set it.

I understand that the 'S25FL256S' has Quad mode register in Configuration Register.

I'm trying to set register as below in EFM32GG11.

qspi->FLASHWRDATALOWER = buffer[0];  // Status Register

qspi->FLASHWRDATAUPPER = buffer[1];  // Configuration Register

It can't update the Configuration Register, but the Status Register can it.

Is it need a command for updating the Configuration Register?

I want to know reliablility of S29GL01GS10DHI010.

- FIT rate (I hear it is "100". Is it correct?)

- Conditions for the calculation (Junction Temperature/Confidential level)

Can you please provide me.

Thanks,

Tetsuo

Good afternoon,

I’m working on an old am29pli60c flash memory.

I have to erase some sectors.

Unfortunately, I’m not able to identify the addresses of each sector.

In the documentation I found :

- If I implement this logic, only sector addresses with 1 bit can be erased (SA1, SA4, SA5 and SA7)

- I don't understand the addressing of the sector SA3

Does anyone have more information about the sector addressing ?

Thanks in advance,

My design use both Zynq-7020 and S25FL128LAGNFM01. The Flash is connected in QSPI mode, but cannot be identified by Zynq. Here is the design.

Does Zynq support SPI or QSPI communication with S25FL128LAGNFM01?

Thanks for any reply.

Is it possible to use S29GL064N90TFI01 or S29GL064N90TFI02 with VIO connected to 2.5V power supply? According to datasheet, it seems that VIO can be in the range 1.65V-3.6V but at page 14, it is listed all models with these notes

01 = x8/x16, VCC = VIO = 2.7 – 3.6 V, Uniform sector, WP#/ACC = VIL protects highest addressed sector

02 = x8/x16, VCC = VIO = 2.7 – 3.6 V, Uniform sector, WP#/ACC = VIL protects lowest addressed sector

Thanks.

Hello Cypress team,

We are working on a Handheld battery-powered medical device. We are using the Cypress S25FL256LAGNFV010 SPI NOR flash as our storage device. We would like the design to be reviewed by the Cypress team. Attached the snippet of the schematic implementation. Could you please review our design & provide your valuable review comments.

Hi,

We are using S34ML01G200TFI003 NAND flash device in our device.

What is the MTBF/Failure rate of the same device.?

Regards,

Harshith
