LoRaWAN MCU

Question

Hi All 
 Looking for recommendations on a low power LoRaWAN MCU ie radio and processor in a single package. 
 Cost is of course an issue. I really need sub 5 USD. 
 Thanks

Ai-Thinker RA-08H is very low-cost. It's $5.14 in quantity of 1250 on the Digikey website, but it's cheaper even in individual quantities from places like AliExpress, so I suspect you could get it for a far lower price from China. 
 Internally, they contain a ASR6601 wireless microcontroller, which has a STAR-MC1 processor, which is closely like an ARM Cortex-M, but is a Chinese variant. Toolchain is available for Linux, with plenty of examples.

My bad, it does LPWAN. 
 STM32WLE4C8U6TR is the cheapest LoRaWAN, still under $4. 
 As michaelkellett mentions U6 and U7 is temp. range.

STM32WL, well below $4.
