Hello everyone. This week, LCSC Electronics supplier Espressif shared their product: the ESP32-C6. It is a Wi-Fi 6 + Bluetooth 5 RISC-V SoC.
SP32-C6 is Espressif Systems’ first 32-bit RISC-V SoC that integrates with Wi-Fi 6 + Bluetooth 5 (LE). It has low power consumption and high-cost performance and can improve the Wi-Fi transmission efficiency of IoT devices. It provides safe and reliable connection performance.
On April 9, 2021, Espressif Systems announced the launch of ESP32-C6, another new product in the ESP32-C series. It supports Wi-Fi 6 functionality for the first time. Currently, ESP32-C6 is certified by the Wi-Fi Alliance. The CPU, memory, and security performance of ESP32-C6 are similar to ESP32-C3. It is equipped with a RISC-V 32-bit single-core processor with a clock frequency of up to 160 MHz, built-in 400 KB SRAM, 384 KB ROM, and supports multiple external SPI, Dual SPI, Quad SPI, QPI flash. ESP32-C6 has 22 programmable GPIO pins supporting ADC, SPI, UART, I2C, I2S, RMT, TWAI, and PWM.

ESP32-C6 is unique in offering support for the 2.4 GHz Wi-Fi 6 protocol (802.11ax) and is backward compatible with 802.11 b/g/n. To optimize and improve IoT device performance, ESP32-C6 supports 802.11ax operating mode with only 20 MHz channel bandwidth and 802.11b/g/n protocols with 20/40 MHz bandwidth. In addition, 802.11ax also supports Station working mode, providing devices with higher transmission rates and lower power consumption. Bluetooth 5 (LE) enables long-distance communication based on Advertising Extensions and Coded PHY. It also supports 2 Mbps PHY for increased transfer rates and data throughput.
802.11ax adds several features to the existing Wi-Fi standard. We selected the parts that can help improve the performance of IoT devices in the design and development of ESP32-C6. ESP32-C6 supports uplink and downlink Orthogonal Frequency Division Multiple Access (OFDMA) access and downlink Multi-User Multiple-Output Multiple-Input (MU-MIMO) access mechanisms, both of which can achieve high-efficiency, efficient and low latency operation in congested wireless network environments. Another feature of the 802.11ax protocol is Target Wake Time (TWT), which allows devices to sleep longer with assistance from an 802.11ax-enabled Wi-Fi access point. This feature will enable ESP32-C6 users to build battery-powered IoT devices that can last for years on battery power and always stay connected.
Espressif continues to safeguard the security of connected devices through hardware and software features. ESP32-C6 includes an RSA-3072-based secure boot, AES-128-XTS-based flash encryption, a digital signature, and an HMAC peripheral for identity protection. Additionally, cryptographic accelerators improve performance. These features ensure that the devices built with ESP32-C6 can provide the desired level of security.
ESP32-C6 utilizes Espressif’s well-established IoT development framework, ESP-IDF. This platform has enabled millions of IoT devices, and ESP users can effortlessly create ESP32-C6 applications using a familiar development environment. If users want to use ESP32-C6 as a coprocessor for an external host, they can choose Espressif ESP-Hosted and ESP-AT firmware.
ESP32-C6 supports Matter and can build Matter over Wi-Fi terminal devices and Matter over Thread terminal devices to achieve seamless communication and collaboration of multi-system and multi-platform smart home devices. It can build other Matter solutions such as Thread border routers, Matter gateways, and Zigbee bridges.
