24LC64 Cannot save data

Postby ailexs » May 30th, 2017, 2:18 am

Hello, there :D

I am quiet new to electric feild. Can you give me some advice about the following doubt?
MCU program can work as normal. However, 24LC64 can’t save data. After that I choose another products, it can operate.But I am so curious about that:
The non-performing product 24LC64 have detected the circuit and showed it is normal. The bus input voltage is 5V SDA SCL. The normal output is bewtten 4.85V to 4.9V. But here the output voltage of non-performing product is bewtten 1.75V to 1.85V. SCL is bewtten 2.0V to 2.5V.
I would like to ask that what reasons lead to the 24LC64 can’t save? This is the 24LC64's datasheet: http://www.kynix.com/uploadfiles/pdf/24LC64-E2fP_61452.pdf.

Waiting for your reply.
Best regards,
ailexs
