STSPIN32F0: 3.3V external supply

MallikarjunSE

Hello, 
I'm planning to use 4xSTSPIN32F0 on one PCB and I was planning to use one input supply(3.3V, 1.5A) for all 4xSTSPIN32F0. I'm struggling to understand power architecture of STSPIN32F0 when using 3.3V supply. Does it need separate 12V at VREG12V?
Thank you!
