TCA9543A: TCA9543APWR

Part Number: TCA9543A
Other Parts Discussed in Thread: TS5A23157, TS5A23159

Dear Team,

I am currently facing an issue with two camera modules having the same slave address on the I2C bus.

To resolve this problem, I have incorporated the TCA9543APWR in my design, which serves as an efficient solution to the address conflict.

But whether it can support over the CCI I2C bus. Or specific driver needed for the use?

Thanks,
Manikandan R.

CCI is a subset of I²C. The TCA9543A works on the electrical level, so it supports CCI.

(The TCA9543A is controlled through the same I²C bus. A general-purpose analog switch like the TS5A23157 or TS5A23159 would be cheaper, but would require a separate GPIO signal to control it.)
