How to find stock of STM32L476J*Y*P parts, or other STM32L476 parts, or any STM32 parts with special SMPS pin assignments. The SMPS feature is not listed on st.com or digikey, etc. Virtually impossible to discover if any parts with feature are for sale.

Hello @TCora.1​  and welcome to the Community :),

I escalated your request internally, and we will contact you as soon as possible.

Thanks for your contribution in ST community.

Digikey shows 12 hits for a search with both STM32 and PTR, which finds parts with P as the last character before the TR for Tape Reel. The final P seems to be the ST convention for the dedicated SMPS pinout parts. Maybe not universally true. 2 part nums are actually orderable,

100 and 144 UFBGA's. Not helpful to me, since I need the smallest part I can find, like a 36 or 72 WLCSP. My project requires low power, size, and weight, under 5 mm footprint.
