Micro-controller: ESP32-C6
ESP32-C6
The ESP32-C6 is a low-power, cost-effective SoC developed by Espressif Systems. It integrates 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE), and 802.15.4 protocols, making it ideal for IoT and smart-home applications. It is powered by a 32-bit RISC-V processor with a clock speed of up to 160 MHz, offering efficient performance for connected devices.
Key Features
The ESP32-C6 supports Wi-Fi 6 (802.11ax), which includes features like OFDMA for efficient data transmission, MU-MIMO for improved downlink performance, and Target Wake Time (TWT) for extended battery life. It also supports Bluetooth 5 (LE) with long-range capabilities and 802.15.4, enabling compatibility with Thread and Zigbee protocols.
The chip includes 320 KB ROM, 512 KB SRAM, and works with external flash memory. It offers 30 GPIOs (QFN40 package) or 22 GPIOs (QFN32 package) with support for interfaces like SPI, UART, I2C, PWM, and ADC. Additionally, it features a 12-bit ADC and a temperature sensor.
Enhanced Security
The ESP32-C6 provides robust security features, including RSA-3072-based secure boot, AES-128/256-XTS flash encryption, and cryptographic accelerators. It also supports a Trusted Execution Environment (TEE) for secure software separation.
Development and Software Support
The ESP32-C6 is supported by Espressif's ESP-IDF, an open-source development framework. It also supports ESP RainMaker® for AIoT product development and can function as a communications co-processor using ESP-Hosted or ESP-AT firmware.
Applications and Use Cases
The ESP32-C6 is ideal for Matter-compliant devices, Thread end-point devices, and Zigbee Matter Bridges. Its low power consumption and advanced connectivity make it suitable for smart-home devices, IoT sensors, and embedded systems.
Important Considerations
Unlike some other ESP32 variants, the ESP32-C6 lacks native USB support. It uses a built-in USB Serial core for debugging but cannot act as a USB device like a mouse or keyboard. Additionally, it has fewer GPIOs compared to the ESP32-S2 or ESP32-S3.
