I started a project in a few years ago and NXP's i.MX 9 line of MPUs were beginning to be released but they were largely unobtainable so I went with a beefy i.MX 8. At this stage, it's way more power than I need and I'd like to move to a much smaller MPU. I was planning on getting the smallest i.MX 8 but the i.MX91 is the smallest cpu they have. I was wondering if I would be better off with the 91 instead of a more mature 8. Thermals are my primary concern so I would assume new is always better, but I just don't know if they are "there yet" since they are still fairly new. A more apples to apples port moving to an 8 could also be a motivator.
Hi @ceva156
What is the main purpose of your project? Which IMX8 series product are you currently using?

Hello,
Don’t need the heavier multimedia GPU capabilities of the i.MX8, the i.MX91 could be a much better fit and give you a simpler, lower-power design.
