Non Volatile RAM (F-RAM & NVSRAM) Forum Discussions
CY15B104QN-50SXITを使用し、データのロギングに使用しようとしています。
SPI通信処理を含むサンプルコードやライブラリなどはございますでしょうか。
ターゲットのプロセッサがCypress製品のMCUではないため、
C言語で記載されているGeneralに使用できるものが望ましいです。
FMxシリーズやPSoCシリーズのライブラリ(PDL)がそのまま使えるのであればそれでも構いませんが、
そのままは使えないと認識しています。また、アプリケーションノートには該当しそうなものを
見つけることができませんでした。
(あればご指摘お願いします)
宜しくお願いします。

Obsolete code STK12C68 has several packages.
What is the functional difference between the 28 pin PDIP 300mils package and the 28 pin CDIP Side Braze DIL package (300 mils)?
does the "Side Braze DIL" require different attention than the "Plastic DIP"?
Thank you
Show LessHi,
I am using FM25V20A and I would like to write some data into memory locations. If I try to read the locations, then I am getting random values.
What is the default value (for example, 0xFF or 0x00)

Show LessHi,
While accessing this FRAM of I2C interface, the CPU may be reset.
When the CPU accesses FRAM after returning from reset, FRAM cannot output data normally.
This FRAM only has a power-on reset and no external reset.
Does FM24C16B-G have a software reset?
For example, MB85RC16V(Fujitsu) has the following description.
It seems that software reset is performed by sending 9 times clock to FRAM.
Is this function effective for FM24C16B-G?

Show LessHi there,
I'm searching the footprint pattern for the FM25V02A (DFN 4mm x 4,5mm x 0,8mm).
I didn't find any related documents on that.
Would be great if someone can help!

Hi,
Minimum operating voltage of this FM24C16B-G is 4.5V.
What is the power-on reset voltage of FM24C16B-G.
Reset operation occur when the voltage drops below 4.5V?

Show LessWhat is the die difference between FM25V10 and FM25VN10? We have qualified the former and want to use the latter in its place without going through a re-qualification. Thanks
Show LessHi,
I am planning to use nvSRAM in my design.
In ordering information there is a option to select Die revision.
What is the difference between Blank(No Rev) and A (1st Rev).?
Which revision is better ?@
Thanks,

Show LessHi ,
I am using a QSPI-FRAM part :CY15B104QSN in my custom board . i am using TI SDK for AM6546 platform and unable to find any driver file in the source .
Would like to know if there is any driver support available?
If yes what are the changes required
Any Inputs would be helpful

Show LessHi .
On three different supplies from official suppliers such as Mouser Electronics, the dimensions of the case do not match the Datasheet on the product. In all recent deliveries, the length of the enclosure was between 21.12 mm and 21.30 mm. The maximum length on the Datasheet is 20.878 mm.
Has the SOIC 32 for the CY14E256LA-SZ25XI been modified or are there any tolerances that may exceed the maximum length?
