  • FM22L16-55-TG のメモリプロテクションが保存されない。

    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...

  • 关于FM24CL16B数据丢失(错误)的问题

    一款产品上使用FM24CL16B,在启动或关闭机器时刻,如果开关抖动多次的情况就可能会出现数据错误的现象,但是存储单元还是好的可以再读写,仅仅是原来存储的数据丢失了。开关抖动可能引起较强的电磁干扰,我怀疑是强烈的电磁干扰导致FRAM内部数据被改变。 问题如下: 1.我所怀疑的 “电磁干扰是导致FRAM内的数据被损坏的真正原因” 是否正确?或者是有其他什么原因会导致数据丢失? 2.你们的其他客户是否遇到...
