Non Volatile RAM (F-RAM & NVSRAM) Forum Discussions
Hi, We are using FM25CL64B-DG FRAM. What is the default value on the memory locations ? is it 0x00 or 0xFF ?
I am reading 0xE0 value at the very first startup.
Thanks,
Anuj
Show LessHi All.
We encounter problems with the FM28V020-TG labelled FM28V020-TG G619370 1901 TW. They simply don't work. No write, always reading 0xFF on all addresses.
Same chip labelled FM28V020-TG G620704 1719 CHI is working as expected.
We can reproduce this problem with three of the 1901 TW on our hardware. All other hardware is fitted with 1719 CHI types.
Are there any known issues on this 1901 TW production batch?
Thanks in advance.
Best regards
Dirk
Show LessHello,
we are using the CY15B102Q-SXE FRAM.
We would like to simulate our HDL and need HDL or some other form of BFM to work in Modelsim.
Are there any simulation files available for the CY15B102Q-SXE?
Thank you,
Eric
Show LessWhat is CY15B104Q-LHXIT absolute maximum junction temperature ?
After installing a FM24CL16B in a DS3231 replacing an EEPROM where power is 5V, I noticed the datasheet state this fram should work at 3.6 volt
Could this IC work with 5 V supply or should I expect a shorter operating life.
Thanks.
Show LessI use CY15B102QSN.
This device has a hard reset. Will the data be All 0 when I do this?
The data sheet describes the behavior of the status register. However, there is no description about the data.
Thanks,

Hi All
Is the factory default value of the SPI/QSPI Excelon data area all FF or all 00?

Hello,
I just got a CY15B108QN-40SXI to work on my project with STM32 board. The marking on the chip doesn't seem to match with its part number.
It has information printed as follows:
CY15303
A 642099
CYP2049
I could not find the chip-marking information on it's datasheet which was last revised on 15th July 2019.
Can someone pls confirm if I received the correct chip?
Thanks,
Regards,
Sailesh..
Show LessHi, For I2C FRAM, I can see 'C code' examples in Cypress Site. I am using MAX2 CPLD to access I2C FRAM. If you know of links that may have the VHDL or Verilog Code, please let me know. Thanks.
Show LessA causa dell'attuale carenza vorremmo utilizzare FM25640B-G2TR RAMTRON DC 2010 che abbiamo in magazzino invece di FM25640B-GTR che al momento è difficile da trovare .
Qualcuno conosce la differenza tra i due tipi? Non sono riuscito a trovare la scheda tecnica di FM25640B-G2TR sul web.
Grazie
