Could you help to check the Core power cost of 10CL040YU484C6G? I'm using the 1.2V /1.5A(max) power to supply it, not sure it's enough or not.
The core voltage, VCCINT can be 1.2V / 1.0V. As long as your supply voltage is meeting these requirement, it would be ok to use it.
I believe it should be ok. However, to check the total current drawn, you may use our estimator tool available at link below:
