Teensy 4.1 big brother

I have not looked too closely yet, but are these boards offered for sale? price?
Arduino support? Zephyr support?

They're not, he designed the board in the video and explained his plans. Which are to write the base drivers to blink LED's and such. With the amount of work to write drivers and such - if one wants to utilize all the bells and whistles. I don't think it will ever be a public release unfortunately.

Note with Zephyr, potentially a lot of this is already done... That is there are already a couple of boards with Zephyr support like:

Note sure how well they work, but...

Teensy with 1GHz RT1170. Pretty please with sugar on top 🙏

PJRC decided to skip RT1170 and focus on NXP's next generation.

I can't talk about anything I might know of NXP's future products which isn't yet published on their public website. PJRC does have a NDA with NXP, which is how we got an early start to be able to begin the Teensy 4.0 beta test in December 2018 (at the time with RT1052 on the earliest beta) and later access to the security info to make Lockable Teensy. Much as I might like to share, I definitely can't talk about any NXP confidential info I might know.

But it's no secret that ARM released Cortex-M85 a few years ago, where "released" means their business partners get to start designing chips. Already a couple chips have been announced by ST and Renesas. If you're wanting to look forward to the not-too-distant future of higher performance microcontrollers, quite a bit of info about Cortex-M85 is public. Just as Cortex-M4 is now the prior generation, so too will Cortex-M7 become the prior gen in the coming years.
 
1 MB SRAM and MIPI DSI is useful for large LCD.
Looks like IO ports is 5v tolerance.
Only CAN FD x2. The Teensy4 has CAN x2 and one CAN FD. Shame no CAN XL.
 
Thank you Paul for this very useful information. My only worry is that M85 as "cutting edge" technology will be 2x as expensive as RT1170, and as M85 seems to be 30% faster than M7 clock-for-clock, so performance per dollar might be better for M7 part. Pure speculation/wild guess.
