I did not see ESP_Sprite mention of the CAN controller in the 30pages here. I hope we've kept the CAN controller. And as mentioned above, do consider adding another controller i.e. if that ship hasn't sailed already.
And as a nice to have, make that a CAN-FD controller which supports up to 5 MBaud.
Eg: https://www.nxp.com/docs/en/fact-sheet/ ... TRLFUS.pdf
Do consider putting out reliability & quality information for the hardware. By that I mean publish the Mean Time To Failure (MTTF) or Failure In Time (FIT) information. I am sure(hope) such testing was done for the ESP32. This is much needed in IoT applications in the industrial/automotive environment. On that note, I'd be very grateful if this info is already available for the ESP32 and anyone can point me to that.
High Temperature Operation
Hope the chips continue to be made for the -40°C to +125°C temperature range.
Increased Encryption Bits
Be nice if the chip directly supported storage of hardware encryption keys. Say about 16 keys, each being 256-bits. If I recall correctly, I think the current number of bits available for the user are 768 bits.
Memory Protection Unit (MPU)
Is there going to be support for MPU in the next chip? Be nice to be able to physically guard/restrict application software to the MPU and from accessing any other memory outside defined interfaces.
Just any more complete support of WiFi is better. You will be competing on the completeness of support of the WiFi stack and flawlessness of its functioning with all upcoming contenders. We already see a problem with 802.11b only devices, or devices that had 802.11g and 802.11n support, but had software not configured for use with them. We also had a client who had a device with a buggy Atheros 802.11N implementation that only agreed to connect to Atheros APs
