New ESP32-P4

[globoy]

This looks like it could be fun.  Espressif is finally fielding a more general purpose micro.  2X 400 MHz RISC-V + 1X 40 MHz low-power RISC-V + decent on-board RAM and a bunch of peripherals.  No on-board radios.

Not a lot of other detail or availability yet but I guess there are dev boards out there now or soon.

I wonder if this device has better ADCs compared to the other ESP32s otherwise it is an utter fail to be a regular microcontroller.

I could not find hardware data on the ESP32-P4, removed from their website https://docs.espressif.com/projects/esp-idf/en/stable/esp32p4/hw-reference/index.html

I think Espressif has gone stupid, they need to sack the marketing people choosing model numbers and names. What a mess.
280 items in the Product Selector  IC, SoC, Module, Dev Board - it's all a blur. Then try look for peripherals like ADC or CAN, the webpage seems to do nothing to help.

Everything is an "ESP32", nothing for general purpose timers, major silicon errata over many revs ADC are pretty much useless even with calibration. I don't think they can actually do decent analog on the silicon.
There is the Pico, Solo, WROOM, WROVER, MINI etc. and no idea what that means.
Very hard to find/select a part.

Those are the modules.

Choose your base IC -> Choose module if a module is needed.

edit: interesting some parts of the ADC are shared with WIFI so that would explain the noise on those channels, https://docs.espressif.com/projects/esp-idf/en/v4.4.1/esp32s2/api-reference/peripherals/adc.html

Let's wait for a datasheet.
It looks more like what NXP calls a "crossover" MCU.
Curious about price, power consumption and how much will be documented in terms of registers.

Espressif first announced the P4 well over a year ago in January 23. Hopefully this time it's real and there will be dev kits soon.

No radio's? Hopefully we don't need ESP-IDF as well.

It's quite a coincidence that they have announced this chip again on 1st of april. Makes you almost think it's an april fools joke as we're patiently waiting for this chip for over 15 months.

[rwaters]

Yes, April Fools. 

[SiliconWizard]

The chip was announed in Jan 2023 (18 months ago!) and still no trace of availability. It wasn't announced on an April 1st.
It doesn't seem to be a joke:

https://riscv.org/news/2023/01/news-espressif-reveals-esp32-p4-a-high-performance-mcu-with-numerous-io-connectivity-and-security-features-espressif-systems/

Still not even a datasheet available. Not sure what's up with that. I think that's the first time I've seen Espressif announce a new chip and be so late.

And yes, it'll be obviously supported by ESP-IDF:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32p4/hw-reference/index.html

Note that all links are dead for now. Was hoping to get documentation from that link - nope.
I suppose that people will find a way to program it baremetal once it's actually out there. The reference manual should be enough for that. Hopefully. (This is also possibly on other ESP32 chips, apart from the radio module which is absolutely not documented, something that is common among vendors though.) Since this one doesn't have any radio, this would not be missing here.

If someone has a contact at Espressif, I'm curious what is up with this chip.

Early announcement is likely  for the AI stuff. Announcing AI does more to your stock price than actually releasing it.
