TMS320F280049-Q1: Analog supply VREFHIA, VREFHIB and VREFHIC are cut-off deliberately

Part Number: TMS320F280049-Q1


hi sir/miss,

I would like to know if there will be any adverse effect (hardware degradation/malfunction issue), if at some points of the C2000 operation, VREFHIA, VREFHIB and VREFHIC are deliberately turned off/cut off (becomes 0V). While this happens, other supplies 3.3V and 1.25V powering C2000 will still remain powered.

This scenario will be seen by C2000 every time our application starts up.

Is it OK to have such scenario without damaging the C2000 in the short or long term?

Please let us know as it may impact our design architecture. Thank you.

Appreciate your support.
