What would you like to see in The Next Chip?

Maybe this memory-manager?

Hello,

Things we use in our devices:
- Proper support for HTTPS, the encryption ESP32 is not fast enough. Other devices lack other requirements.
- Larger pin count, now we use IO expanders this cost us 1 SPI interface.
- MAC PHY, we are stuck using the ESP32 for the PHY. Using SPI is not fast enough since its shared with the IO expander
- USB
- WIFI, Zigbee and bluetooth? Ive seen problems with this due to these using the same frequency. Perhaps wifi on 5GHz?

Hello,
my wishes would be:

- a 3-4 core version (I'm programming in Arduino IDE).
Why?
1. Core for all internal things e.g. WIFI, Bluetooth, Uart, SPI etc. -> system/event task
2. Core for fast / time-critical things like querying data from an ADC or similar -> only one task is running here, with my applications the task switching takes too long so that only one task can run
3. Core application, possibly several tasks (web server, save data on SD, UI etc.)
4th core optional from 3rd core

- a much more accurate 12bit ADC (preferably 14bit)

- DMA controller for SPI, UART etc.

- interface for graphic LCDs

Greetings and many thanks for this microcontroller

Wouldn't you be able to combine the 3rd and 1st core tasks and run this on a two-core CPU?

- a much more accurate 12bit ADC (preferably 14bit)
- interface for graphic LCDs

Newer ESPs (ESP32S3 for instance) already have a much better ADC, and the S3 specifically has an interface for graphical LCDs.

- DMA controller for SPI, UART etc.

That already exists from the very first ESP32. You may now know it because the APIs handle DMA details for you.

433 MHz radio.

I think I forgot this in my previous post, but I would really like some always unique hardware ID.

[svenbieg]

I'd like the same pin-layout very much, because i don't like to sell adapters to my customers.

Just make Risc-V C3 Dual core or quad core )
Maybe higher clock too - 240Mhz+

You can use the MAC-address for that, it's guaranteed to be unique.
