Part Number: TMS320F28375S
Hi,
In the controller datasheet (SPRS881G), section 5.9.1.2. It was given that "The 3.3-V supplies should be powered up together and kept within 0.3 V of each other during functional operation".
In our custom board, the supplies are generated from two different switcher IC's and there is a delay of 5mS between VDDA and VDDIO.
Although I'm not having any issue, will this cause a problem to the controller?
Regards
Kiran
