BGS5 connectivity with Controller and Audio Codec | Thales IoT Developer Community

I am going to communicate the BGS5 GSM module with controller and audio codec,
for that, I am going to use a V180 voltage source for voltage translator to UART communication with the controller and the same voltage source for audio codec. So my questions are,
1. Is it sufficient to drive both communications?
2 If not, then should I connect different voltage regulator for 1V8 rail.
Please suggest me some circuit for that. Codec: ***9860 and microcontroller STM32F1
