What 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
Show LessHi.
FM25C160B-GTR is under consideration.
We plan to write 16 bytes of recorded data (including CRC) on one line and the next recorded data alternately on another line.
Since there is no power failure detection circuit, writing by power failure detection is not performed.
If the data becomes CRC abnormal due to a power failure and writing, both lines are read after the power is restored and the CRC normal recording data is adopted.
Can it be used this way (without detecting a power outage)?
Also, for example, does a power outage and writing hit and both lines become abnormal data? ..
Thank you

Show LessHello,
The downloaded document from https://www.cypress.com/file/444186/download,shows on Pg 17, it's endurance limit of 432 yrs, operating at SCK freq of 40Mhz. These calculations r based on reading 64 byte data sequentially.
If I do random Fast-Read continuously then based on the same calculations the endurance cycles/sec comes to 800,000 (this includes CS disable time of 50nSec) and the yrs to reach this limit falls to ~40
I want to know if I am on the right track or there's something more to it?
Thanks,
Regards,
Sailesh..
