Memories Forum Discussions

Hello,

I have custom-designed a PCB that incorporates an MCU board and a Nor Flash, specifically the S25FL512SAGMFMR10 part. Currently, I am developing a bootloader utilizing this Nor Flash.

I intend to use a specific region of the flash (for example, sector 0) to store a footer. My requirement is to update variables located within this footer. However, I understand that updating the footer necessitates erasing the sector, which is not ideal for my application.

Could you please advise if there is an alternative method to erase or overwrite data in the Nor Flash without performing a sector erase? Any suggestions or techniques that could facilitate this process would be greatly appreciated.

Best regards,

I am using CY14U256LA-BA35XI as replacement for STK12C68-L35M replacement. Not using A13 and A14 as only 64kbit is used. HSB not connected as only power ON/OFF autorecall/store function is used. Please review the design and part replacement.

Guten Tag zusammen. Könnten Sie mir bitte mitteilen, ob es sich bei dem S29GL256S11DHVV20 auf dem Bild um ein Original handelt (Marking)?

Wenn ja:

Wir haben diesen für einen Bestückungsauftrag beschafft. Auf dem Board des Kunden sind immer 2 Stück verbaut. Bei dem Funktionstest des Kunden wurde angezeigt, dass ein Speicher 512mb haben soll. Es handelt sich dabei jedoch um die 256mb Variante. Kann es sein, dass sich die beiden gepaart haben und deshalb auf 512mb kommen?

Vielen Dank im Voraus.

Mit freundlichem Gruß:

Hi Team,

    One of the project, I have interfaces hyperRAM S27KS0641DPBHI020 to croslink-NX FPGA. I have hyperram controller IP provided by infineon.  I have written AXI master to communicate with hyperram controller IP which acts as a AXI slave.  

Using AXI master, I am writing 0x00000000, 0x00000013 and 0x00000001 to registers of IP MBAR0, MCR0 and MTR0 respectively and readback successfully.

where 0x00000000 is base address to write/read data in hyperRAM.  

value 0x00000013 to MCR0 to mention device type as hyperRAM i.e. MCR0[4] = 1.

value 0x00000001 to mention initial delay of 6 CLK same as bit 7 to bit 4 of configuration register (CR0) mapped to bit 3 to bit 0 of MTR0.

Even I tried by writing 0x00000033 first to MCR0 address and written value as above to MBAR0 and MTR0 then updated MCR0 to 0x00000013 so that command address CA[46] got mapped with MCR0[5] first 1 for register space then memory space.

I kept reset width of 1 sec for reset IP and delay of 1 msec between IP registers configuration and data write, also 1 msec between data write and read. 

Unfortunately, despite IP registers MCR0, MTR0 and MBAR0 gets configured to value mantioned above I am unable to read data which written to memory, I am not sure data is being written to hyperram or not. 

I am requesting for help in this regard, I stuck in between, I am trying to resolve using datasheet of hyperram but could not solve it. Please guide and suggest how can I resolve it for read and write to memory. I am getting all the signal properly on ILA expect read data. 

Thanks,

Krishna

Hi Dear Authorized,

I am trying to use HyperFLASH over FlexSPI Interface over HyperBUS and some errors occured during test on my custom board which suited by NXP IMXRT1064 MCU. After some research, I learned that LUT Instraction Set is required for LUT Installation to use FlexSPI. Therefore, I need LUT Instraction Set for S26KS512SDABHV030. For example, there are some memories which is used by NXP Users for IMX MCUs like below. Their datasheets contains Instruction Set Table but I can't find for my product. 

Here is my test link which research the solution for Custom Board: https://community.nxp.com/t5/i-MX-RT/IMXRT1064-HyperFlash-via-FlexSPI/m-p/1763855

Could you please help me?

I have interfaced 64MB hyperRAM (S27KS0641DPBHI020) with FPGA on board.  I am using infineon controller, I have written master to handle hyperram slave controller. I am getting expected result in simulation but not unable to read/ write data on actual hardware. 

I have successfully write and read configuration registers, but data is not getting written and read back. I have reset for 10 sec which is much more than 300 microsec and provided delay of 1 sec between registers configuration and data write and lso between data write and data read.

Please suggest proper solution. 

Hi,

Does Infineon / Cypress have radiation test data on FRAM CY15B104Q (full part number CY15B104Q-SXI or similar) or on this part family?

Specifically I am looking for a SEL or DSEE threshold.  I've seen neutron data in this forum, but I am wondering if you have single event effects (SEE) / heavy ion test results.

(Total Ionizing Dose (gamma) would be great too, if you have it)

Thank you!
