Nor Flash Forum Discussions

Hi,

I need to interface with the S70GL02GS flash. I needed the sequence of commands for ersa and program which I am not ale to find in the datasheet. Could you pleasepoint me to a document or provide an example of interfacing with the flash for programming/erasing. I would appreciate both multiword and word by word programming examples

Thanks

Sachin

Dear supporter

Infineon TC3 family has Queued SPI function which can achieve serial interface.

Please let me know if Cypress Quad SPI NOR Flash memory would be suitable on communication with this function in the follwing clock rate.

Please refer to the following spec Page-2.

https://www.cypress.com/file/209446/download

And regarding this definition, "MBps" means mega Bit per sec ? Or mega Byte per sec ?

The following definition shows current consumption with several reading speeds in spec Page-2.

Is the high speed reading value in the following table depend on MCU baud rate setting ?

I am using the low levell driver from the downloads page to try and program the S29GL064S70TFI070 device.

I am finding that some calls to "lld_WriteBufferProgramOp" return with error status "DEV_PROGRAM_ERROR".

Why does this happen and how can I recover from it?

Hi Experts,

Last time I asked a question about "s70fs01gs clarification for CR1V QUAD bit behavior after CR2V QPI bit set to 1" and got result that the CR1V QUAD bit will be automatically set to '1' when the CR2V QPI bit is set to '1'.

Here I got the same question for the part 's25hs01gt', in the datasheet, it has different description from the 's70fs01gs'.

In the s25hs01gt, it only has a description in Table Configuration Register 2 for CFR2V[6] QPI-IT that "Dependency: QUADIT (CFR1x[1])".

Does this dependency means that

1. the "QUADIT (CFR1x[1])" will be automatically set to '1' when "QPI-IT (CFR2V[6])" is set to '1'?

2. or the "QUADIT (CFR1x[1])" should be set to '1' by using 'write register' command before setting to "QPI-IT (CFR2V[6])" to '1'?

Which is the expected behavior for s25hs01gt?

Thanks,

Mike

Does Cypress offer models for timing analysis tools that customers could use to verify interface timing rather that entering all individual parameters. I'm specifically interested in S70FL01GS NOR Flash part interface timing.

Hi,

We are using the below mentioned Boot Flash chip for our application.

     Part no                     -S29AL016J70TFI02 (TSOP-48)

     Top Marking:

                    1st line      - S29AL016J70TFI02

                    2nd line     - 838BB134 M

                    3rd line     - ©07 SPANSION

Issue: The boot flash chip S29AL016J70TFI02 is mounted in two boards. Both the boards are tested for chip erase in room temperature. We observed that the chip erase timing for both the IC's are different. We probed at RY/BY# assertion and found below two different chip erase timings.

Chip 1: 15.5s

Chip 2: 19.1s

What would be the reason for the exceeding the typical chip erase time as mentioned in the datasheet "18. Erase and Programming Performance".

With regards,

Required thermal data for part number S25FL064LABMFM013

like POWER DISSIPATION

AND theta ja,theta jc, theta jb,tj,tc ?

Hi,

I am trying to bringup my controller board with ARM processor using Cypress flash S70GL02GS12FHIV10. My CE# line is toggling continuously as it is not able to read the flash part. If I reset the flash, I am able to communicate successfully.

Could you please help me in debugging this issue? Please let me know if you need any information.

Thanks
