Hello guys,
One of my customers uses TSC2007 for their current products.
I2C communication error between controller and TSC2007 is happened when the product temperature is less than -20 degree C.
The I2C communication speed is 400kHz and signal voltage is 3.3V.
They compared waveforms of SDA and SCL between +25C and -20C. But any timing difference and voltage difference is not found.
Do you have any comment about the communication error cause?
Your reply would be much appreciated.
Best regards,
Kazuya.
