Hi!I use M24LR64E supplied with 3V3 and communicating with PIC microcontroller.I am facing a big and urgent problem: I2C writes are working really fine according to manual specification until the memory is subjected to EMI. After that, any I2C write ...

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 go...

Hi!Thanks for prompt reply.I am already using the 9 Start + 1 Stop procedure, but communication cannot be recovered.When the communication is blocked, SDA line goes to right state (1), I2C master correctly tries to start a new read, for example, but ...

Thanks for replying.I am using 2K2 for pull-ups and the signal on SCL and SDA respects specifications.After many tests, It seems noise "goes in" through the antenna and blocks I2C side. If I cease the noise generator, the I2C side remains blocked. Wh...
