Hi,

I am using SAK-TC367DP-64F300S AA in my project and supplying that MCU with TLF35584QVVS1 (5V variant).

For the VDDP3 pins should I supply the pins with 3V3 externally or is there an internal LDO in MCU that provides the 3V3 supply for the VDDP3 pins?

Hello,

I think you're supply mode is Single Supply as described in "Figure 133 EVR Switch mode topology (a) - 5 V single supply". The 3V3 can be internally generated from EVR33 LDO. Please refer to the section "12.2.2.1 Linear Regulator Mode (EVR33)" in the UM below:
