ESP32 Forum

As I see it now
- separate BT and WiFi
- USB 2.0+
- more cores - 8 would be excellent
- more SPIs and higher SPI clock
- executable external memory
- more ram and psram
- better timer
- configurable clock speed per core?
- improved sleep modes
- hardware button debouncing

Now your just getting into a whole other breed of part.
Might as well get something like this instead.

Except we don't want FPGAs )
Just better MCU board/module from Xtensa

No MCU or SoC around the world can provide 1A on GPIOs ! It is up to you to add some MOSFET to drive such current ...

WOR can not be achieve without having the radio not sleeping ...

What if the chip wakes for small periods to check RF and then goes to sleep again quickly. In the average the consumption would be good.
ESP could also add a feature to let the user (the programmer) decide about the samples rate. It would be similar to other RF transceivers (I used to work with such transceiver from TI)

Actually it's all there in the IDF! Just program and test it! IT's a software feature
It is very possible to do such thing. With Wifi it's pretty hard though, in order to maintain connection. In case of ESP-NOW and MESH, it's possible, so you don't have to keep connected.
You can put the ESP in a sleep state that it still maintains connection while consuming just a couple mA-s, but in this case it consumes more than in deeper sleep states.
No other chip on the market can achieve being in sleep while on Wifi, radios need power to be kept on, and for Wifi you need to keep the radio on all the time, and maintain connection - mostly because of the FHSS, which is a pseudo random frequency hopping of the router that must be followed by the ESP to keep connection stable.
Additionaly you have to keep the RAM powered, to keep the Wifi configuration intact during sleep.

ESP32 would be everyones mcu if it adds:

Long range LoRa or Another Network
Lowest Sleep Current Consumption (While Interrupts Running)
Small footprint without need of Crystals & Rf balun ( Even QFN )
All IOs accessable while wifi running ( IO's Saperate from Rf)

These four things will change Esp32 to a Dynamic Mcu for everyones need.

The RF balun already is internal for both the ESP32 and ESP8266. Wrt crystal: have you looked at the Esp32-Pico-D4?

That does not make sense. Access to GPIOs already is unaffected by WiFi.

ADC-2 does not work when WiFi is enabled....

Ah, check, but that's not a GPIO, that's an ADC.

What would you like to see in The Next Chip?

I now understand why manuf. don't ask this question. I have been following this post since its creation.
Very, very few good ideas, but the majority of them are people wanting to make this chip suit their own goals.
Not to mention trying to throw everything in, and the kitchen sink.

People, this is the a genie in a bottle where you rub it 3 times and make a wish and poof the best chip becomes reality.
The ESP32 is an unbelievable amazing chip already, and for what it costs where else can you find anything else to compare to it?
In reality, the only thing that i see this chip could use is a boost in memory. But even at that, its still VERY practical.
