ESP32-C6 is Espressif’s Wi-Fi 6 SoC that combines 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It has been anxiously anticipated by the market since its first announcement, for it is our first Wi-Fi 6 SoC achieving an industry-leading RF performance, with reliable security features and multiple memory resources for AIoT products. Currently, the ESP32-C6 module and its development board are available to be ordered from Espressif’s online store, and more products will soon become available on Adafruit (module and development board), Akizuki, Digikey, and Mouser.

ESP32-C6 consists of a high-performance 32-bit RISC-V processor which can be clocked up to 160 MHz, and a low-power 32-bit RISC-V processor which can be clocked up to 20 MHz. ESP32-C6 has a 320KB ROM, a 512KB SRAM, and works with external flash. It comes with 30 (QFN40) or 22 (QFN32) programmable GPIOs, with support for SPI, UART, I2C, I2S, RMT, TWAI, PWM, SDIO, Motor Control PWM. It also packs a 12-bit ADC and a temperature sensor.

ESP32-C6’s support for IEEE 802.15.4, Wi-Fi, and Bluetooth 5 (LE) connectivity, enables customers to build Matter-compliant, Wi-Fi- and Thread-end-point devices which, therefore, achieve interoperability in smart-home scenarios involving chips from multiple brands. Moreover, ESP32-C6 can be used in various Matter-related solutions, such as Matter Gateways, Thread Border Routers or Zigbee Matter Bridges.

ESP32-C6 is going to be supported through Espressif’s open-source ESP-IDF, so that our customers can benefit from their familiarity with our field-proven platform that already powers millions of connected devices. For customers who would like to use ESP32-C6 as a communications co-processor with an external host, ESP-Hosted and ESP-AT firmware can also be available. ESP32-C6 will also be supported through ESP RainMaker®, Espressif’s complete system for building AIoT products.

ESP-IDF v5.1, currently in development, will include initial support for the ESP32-C6 chip. Espressif’s VP of Software Platforms, Ivan Grokhotkov, has just released a comprehensive list of all the ESP32-C6 features that will be supported in ESP-IDF v5.1. The list can be found here.
