SHORT CIRCUITING VDD AND VDDC WHEN NOT USING DEEP SLEEP

[xarowubas]

Hello,

I'm designing a custom board around T1040. Since I'm not implementing deep sleep functionality, can I short circuit VDD and VDDC together and source them from single regulator ? This way they will both ramp up together. Will this cause any problem ?

According to the T1040 Datasheet, chapter 3.2 Power sequencing:

When Deep Sleep is not used, it is recommended to source VDD and VDDC from same power supply.

Have a great day,
Andrei
