⚙️ ESP32-C6
RISC-V Performance with Wi-Fi 6 and Bluetooth 5.3
The ESP32-C6 represents the latest step in Espressif’s evolution — bringing Wi-Fi 6, Bluetooth 5.3, and an open-source RISC-V CPU together in one energy-efficient chip.
It’s designed for next-generation IoT and connected devices that need faster Wi-Fi, stronger security, and lower power draw than ever before.
If the ESP32-C3 was the minimalist RISC-V MCU, the C6 is the upgrade — adding cutting-edge wireless capability and more advanced hardware acceleration for modern embedded systems.
🧠 What Makes the ESP32-C6 Stand Out
The ESP32-C6 is built around a single-core 32-bit RISC-V processor clocked at up to 160 MHz, with Wi-Fi 6 (802.11 ax) and Bluetooth 5.3 radios integrated on-chip.
It’s optimized for low-latency connectivity, fast data throughput, and secure communication — ideal for IoT automation, Matter-enabled smart devices, and edge computing.
Key Features
- Single-core RISC-V 32-bit CPU @ 160 MHz
- Wi-Fi 6 (802.11 ax) + Bluetooth 5.3 LE
- 400 KB SRAM / up to 4 MB Flash
- Improved security features (AES, SHA, RSA, ECC, HMAC)
- Up to 30 GPIO pins with I²C, SPI, UART, ADC, PWM support
- Deep-sleep modes < 10 µA
- Secure boot + flash encryption
- Compatible with Arduino IDE and ESP-IDF
The result is a chip that delivers faster, more stable connections — even in crowded wireless environments — while maintaining Espressif’s hallmark efficiency.
