microcontroller - P CHANNEL MOSFET gate directly GPIO


I'm currently using this circuit to control my load from MCU logic HIGH


It works great, after self reflexion why just not do like this ?


What is the difference from the first circuit ? It's safe for my MCU ? I use NDP6020P is a Vgs(th) max -1V my VCC is 3.7V.


I know in the last circuit when MCU is LOW my load is "ON" instead the first circuit "LOW" = "OFF"


Regards

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
