M24LR64E-R RF WIP/BUSY pin strange functioning in noisy enviroment

[BMace.881]

Hi!

I am working with M24LR64E-R in a design (in production) and it works really fine in a non noise enviroment. I am using RF WIP/BUSY pin to inform microcontroller RF BUSY state so as to stop I2C communication.

The problem I am facing: RS BUSY pin goes 0 for aprox. 20ms when the product is subjected to noise. Even trying to use RF WRITE IN PROGRESS mode, the result is the same.

Have you ever seen it? How can I work around?
