Hi citoyx,

But this no info about what riscV core is it and who is the factory maker of this chip.

The RISC-V core is a custom design. It supports the RV32-IMC extensions. More details about the CPU will be published in the ESP32-C3 Technical Reference Manual which is currently being finalised, thanks for being patient.

The "factory maker" for all Espressif chips to date is TSMC, Espressif is a fabless semiconductor company which means we design our own chips but the silicon is fabricated by a third party foundry.

Super im eagier to read the spec !
Btw, will it be baremetal, or with freertos framework ?

FreeRTOS. Expect all of the new chips we bring out to use ESP-IDF/FreeRTOS by default, same as the ESP32/ESP32S2.

update:

ESP32-C3 Technical Reference Manual is online
