Non Volatile RAM (F-RAM & NVSRAM) Forum Discussions

Hello Cypress team, I have a question about using Linux-SPI-NOR driver to access NVSRAM and read/write data to it. I have refered this commit. https://community.infineon.com/t5/Non-Volatile-RAM-F-RAM-NVSRAM/linux-support-for-CY14V101QS/td-p/337270 I added the JEDEC_ID in the support table of linux spi-nor driver, now I can see the NVSRAM has been mount as /dev/mtd6 by linux spi-nor driver. I can also read data from NVSRAM, but I have been unable to write data. After confirming the datasheet, I found that if I want to write data to NVSRAM, the MAX frequency must be set to 108MHz. But the board I use can only support SPI frequency up to 25M Hz... Therefore, I have a question of it. For reading/writing the data from NVSRAM, what should the frequency be set to that SPI reading command & writing command can be worked? Thank you! Best Regards, Andy Wang Show Less

Hi Guys,

May I know the difference between FM24CL64B-G and FM24CL64B-G2TR please?

Not asking about TR, but "2"

What exactly this "2" stands for?

 

Thank you

Dear Sir or Madam,

I am using CY15B108QN-40SXI(Blank/T) in our product.
Please provide RoHS Certificate(2011/65/EU, (EU)2015/863) for CY15B108QN-40SXI(Blank/T).

Thanks.

May I know CY15B102QN-50SXI read/write performance?

Have any test report for reference?

Is ideally use maximum 50Mhz calculate without overhead will be 50mbit/s?

Regarding  FM28V202A-TG, 

When did FM28V202A qualify for Rohs 10( Rohs II)?

Best regards.

I am currently developing a product with the FM25L04B to be used as NVM. We currently have about 56 bytes of data needed to be wrote to the NVM to be saved. Am I able to write all of these bytes one after another after supplying the starting address, or do I need to break it up into two writes since a page only contains 32 bytes?

We can find CY14B116L-Z45XI parts on website.

https://www.infineon.com/cms/en/product/memories/nvsram-non-volatile-sram/cy14b116l-z45xi/

But ordering information can't find it.

Please help check to provide correct datasheet.
