Hmm, doesn't say what "instruction set profile" it supports.

Is this Espressif's first core without any wifi or bt?

Hopefully it ships. There's a bit of a backlog of cores announced >1 year ago that are still nowhere to be seen. (ex: ESP32-C5 and -C6 with 802.11ax.)

I wonder if perhaps they are having trouble securing manufacturing capacity for analogue chips?

By dropping WiFi and BT, they can use a different production process in other foundry's.

rektide
I'd guess they're shooting for a higher performance process & that it just doesnt work very well for the analog/rf design a wifi chip might use. Or they're just not experienced yet adapting tbese smaller nodes.

I'd love to know what kind of nodes various bits of wifi hardware so use. And what nodes existing (all wireless capable) Espressif chips are on.

Maybe next year we'll see this chip paired with another die in the same package for the analog stuff adding in WiFi, Bluetooth, an ethernet Mac, a 1 watt audio amp, an analog mux, and all the other things to make it a real 'system' on chip.

Dont forget about a GB of ram, and maybe some DC-DC converters. ;)

Espressif is expanding their product line too quickly.

note: they decided not to included wifi or bt

sureglymop
Not including those is a pretty good "Security feature"

But isn't espressif's main "value proposition" the included wireless stack?

I'm not super in tune with the RISC-V scene, but if a person is working with RISC-V right now, are they also concerned with wireless?

I realize that the answer is in a way "yes." But, if you can only choose one, wouldn't someone working with RISC-V be looking at security over Wi-Fi?

For ESP8266 and the original ESP32 yes, but there are use cases for wired IoT and they also get to sell 2 chips instead of 1...

Sorry I should have made it clear. My 2 remarks are unrelated to each other.

I was just noting it because it's notable.

I'd imagine they're just going to leverage SDIO and a cheaper ESP32 variant (like a C3) to bring wifi to the chip. Makes sense when you start looking at EMC/EMI with high speed interfaces, adding Wifi just adds another layer to the chaos which might not be needed in a lot of applications

No MII, No bt, No wifi. Bold strategy as those things are what made ESP32 popular.

It has Ethernet no? I think this part will be awesome for lots of stuff.

This stuff just keeps getting cooler and cooler. Wonder what the price point will be on these? Hopefully right in line with the rest of their offerings!

Extremely excited to see what we can do with MIPI CSI/DSI, H264 encode, and JPEG encode in a tiny micro like this one. I can definitely see the value in this part

Great looking chip!

Lots of RAM and a DAC, great for VGA.

But no wifi?
