FM22L16のマニュアルには、 ソフトウェアによるライトプロテクトが可能で、設定は不揮発性と記載がありました。 マニュアルに記載されているシーケンスを実行し、ライトプロテクトをかけることができましたが、 ライトプロテクト後、電源OFF、ONすると、 FRAM内のデータは、保持していましたが、ライトプロテクトが解除された状態になってしまいます。 シーケンス等、電源の落ち方など、ライトプロテクト... Dears， 请帮忙提供一下：SOIC-8 208MIL 封装的铁电的卷带包装宽度参数，多谢！ Hi, we are having issues with BP1 and/or BP0 being set seemingly random after a write to the FRAM occured. We have one board design with said FRAM chip and it occures on all of the tested boards to date (aroun... HI dear friends, Pls advise what are the differences between "10ZI" and "10ZXI" parts. Are the "10ZI" parts not Pb-free? But there is square mark (Pb-Free mark) on the parts. Or is it normal? Pl... I'm working with CY15B116QSN device using 002-26981 preliminary datasheet. I've developed a VHDL FRAM access engine and now i'm simulating the FRAM behaviour. I'm using QSPI access @ 67,5MHz. In the t... Can Cypress provide the projected maximum density pin connections for memory packages to allow customers to attach higher density parts? Higher density parts may be required when customers run out of memory or if the ... Hello Can anyone confirm if the top markings of this component are correct for the component. top marking documents are not helping us to identify it is the correct part. Part CY15B104QI-20LPXCES... Autostore: VCC < VswitchとなりStore処理が開始されたとき、 ・Store処理が完了する前に、VCC > Vswitchとなった場合の内部挙動はどうなりますか。 また、SRAMとnonvolatile elementのデータは壊れてしまいますか。 Hardware RECALL: ・VCC > Vswitchとなり、RECALL処理が開始されたとき、 t... Hello, I would like some help to set up or correct my SPI communication. I've been looking for two days now and trying to make changes in vain and I don't know if the problem is in the pin configuration or in the SP... Hi, Cypress doesn't provide serial F-RAM part-numbers working in the -55/+125°C range. The widest range available is the automotive range (-40/+125°C). Is it something impossible with the F-RAM technology ... Hi Im trying to read the device ID initially to start interfacing with FM25V10 FRAM. The below mentioned procedure I'm following to read the devive ID C22400h - with product family,density... We're using a PIC32MX family MCU and communicating with the F-RAM via SPI. We can successfully perform hundreds of writes to the F-RAM before we see the device return seemingly invalid content from a RDSR comman... Hi Can anyone direct me to a chip programmer supplier that can read/write to the CY14B256LA? regards, Tony. I'd like to inquire the IBIS model for CY15B102Q-SXE to perform signal integrity analysis. I was able to find an IBIS model in the developer community forum. However, the typical voltage in the IBIS model is 2.8V as o... nvSRAMのSTORE/RECALLは、すべてのアドレス(すべてのデータ)を同時にSTORE/RECALLするのでしょうか。 nvSRAMを使用検討する前に、SRAM+Batteryの運用をしていましたが、 SRAMの際には電源が中途半端に落ちたときなどに、データが全部壊れず、一部のみ壊れることがありました。 SRAMからSONOSへのSTOREが全bit同時に書き込むのであれば、 その後に正... Hello! We have a question about top marking on FM25V20A-DGQ We got FM25V20A-DGQ with this marking: Q5V20A 631094 1731 Is this normal? Unfortunately, we can't find information in Datasheet about "... Hello, We are using PN FM25V05-G in our design, but was provided the information for Rev AB of that PN. I have been told that Rev AB is no longer current. Can you please provide the latest revision letter for this... Hello! I'm interested in 16Kbit FRAM with its own unique read-only ID. Detailed information and questions are described in the attached document. What device can you suggest based on the requirements? ... dear The IC marking we got with C/O TW this time is different with previous C/O CHINA. Why marking with 2 dimples for C/O TW? I can't find datasheet with 2 dimples in website, can provide? thx a lot! Hell Experts, We are using CY14B104LA NVSRAM as external peripheral connected to AM5708 ARM custom SOC via GPMC based on chip select information. Could you please let me know the timing parameter...
