您好!

我的机器人板卡上使用了一颗FM22LD16,  板卡上方有一个电机,在此应用场景下,铁电容易读写错误,拿到实验室下,读写错误现象消失,请问是否存在电机对铁电的影响?谢谢

Hi Sir

An FM22LD16 is used on the board card of my robot, and there is a motor on the top of the board card. In this application scenario, f-ram is easy to make reading and writing errors. When taken to the laboratory, the phenomenon of reading and writing errors disappears. Is there any influence of motor to  F-ram?

thank you

会不会是在实际应用场景下电机运行的时候F-RAM的供电不稳啊,建议示波器抓一下F-RAM的波形,和数据手册的A/C参数比较一下 看有没有异常。

F-RAM磁场抗扰能力还是很优秀的:
