130 I/Os in an 11x11 BGA — routing reality
The 169-ball UBGA footprint is 11 mm square. With 130 I/Os brought out, the ball pitch is tight — expect four-layer minimum on the PCB to escape the inner rings.
That means the part is characterised for cold starts in unheated shelters and for self-heating inside a sealed enclosure near a motor drive. The commercial-grade sibling (10M04SAU169C8G) is rated 0°C to 85°C and costs slightly less, but for any outdoor or engine-bay deployment the I7G is the correct call. No derating guesswork.
