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

Hi.

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

Good day!
Purchased a microcircuit CY15V102QN-50SXE. 
It has markings on it:
CY15281
B 610111
CYP1913
Please tell me what this means?

Hello,

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,

FM25V05的SO在输出数据是正确应该是高还是低

Hello,

We plan to use your CYPT15B102Q-GGMB type F-RAM as an Engineering Model  and its QML-V version as a Flight Model.  

According to the below Ordering Information, 5962R-182160101VXC is given as QML-V type code but it looks different from the Standard Microcircuit Drawing  Part Identifying Numbers. The Device type designator (01) appears to be written twice in the part number.  The corresponding Standard Microcircuit Drawing Number 5962-18216 and related document couldn't be found in the DLA records. If this information is available, is it possible to send it to us? Also, the part number 5962R-182160101VXC can not be found in the QPL list.  Because of the mentioned F-RAM is Radiation Tolerant, not Radiation Hardened,  is it correct to have the letter "R" in the Part Identifying Number?

What is the technology of the mentioned F-RAM? Can we say CMOS?

Is there a MTBF or FIT value for the mentioned F-RAM?

Thanks & Best Regards,

Hi Cypress

We have some question about FRAM application ,
1. How time is it when write a 16Mbit in CY15B116QSN-108BKXIE , Can you take a example for it .
2 Is it can work in Linux system with file system .Thank !!

We were using the FM24C04-S (soic8) on some older boards and now that part is obsolete, so my question is…Can we use the FM24C04B-G part (soic8) as a replacement?

We have a product using CY15B104QN-50LPXI. For lack of availability we are planning to use the part CY15B104QSN-108LPXI. Is this part a drop-in replacement? Should we make some preliminary test?

A 1 Mbit SPI FRAM (FM25V10-G) appears identical to a 1 Mbit SPI nvSRAM (CY14V101Q3-SFXI) from a user perspective.
What are the key differences between these technologies?

For which applications would one be preferred over the other?

Are they interchangeable in a design?
