# ESP32-C6 Specifications
|
||
> **芯片：esp32-c6** | **类别：specs** | **信源：** [Espressif 官方文档](https://docs.espressif.com)
|
||
|
||
## 1. Core Architecture
|
||
- **CPU:** Single-core RISC-V, 160 MHz（HP CPU）+ LP RISC-V 20 MHz（协处理器）
|
||
- **Wireless:** Wi-Fi 6 (802.11ax, 2.4GHz, 20MHz only, 1T1R), BLE 5.3, Zigbee/Thread (802.15.4).
|
||
- **Application:** Next-gen Matter nodes, mesh networking, Wi-Fi 6 efficiency — IoT 芯片首次支持 WiFi 6.
|
||
|
||
## 2. Memory
|
||
- **HP SRAM:** 512 KB internal.
|
||
- **LP SRAM:** 16 KB.
|
||
- **ROM:** 320 KB.
|
||
- **Cache:** 32 KB L1.
|
||
- **eFuse:** 4096-bit.
|
||
- **外部 Flash:** max 8 MB QSPI.
|
||
|
||
## 3. Peripheral Mapping
|
||
- **GPIO Count:** 30 (QFN40) / 22 (QFN32).
|
||
- **ADC:** 7 channels, 12-bit（仅 ADC1, GPIO0–6）.
|
||
- **DAC:** **None.**
|
||
- **Touch:** **None.**
|
||
- **Hardware PWM:** LEDC 6ch + MCPWM.
|
||
- **UART:** 3（2 HP + 1 LP）, max 5 Mbps.
|
||
- **I2C:** 2（1 HP + 1 LP）.
|
||
- **SPI:** 3（1 通用 SPI2）.
|
||
- **I2S:** 1 controller.
|
||
- **CAN (TWAI):** 2 controllers.
|
||
- **USB Serial/JTAG:** 1（GPIO12/13）.
|
||
- **SDIO 2.0:** 1（从机）.
|
||
- **PARLIO:** 1（并行 IO）.
|
||
|
||
## 4. Hardware Safety & Constraints
|
||
- **ADC/WiFi Conflict:** **None.**（C6 只有 ADC1，无 ADC2，RISC-V 架构已修复）
|
||
- **Flash Pins:** GPIO24–29（待核实确切范围）.
|
||
- **Strapping Pins:** GPIO4 (MTMS), GPIO5 (MTDI), GPIO8, GPIO9, GPIO15.
|
||
- **LP GPIO:** GPIO8–21 可用作 LP GPIO，由 LP CPU 直接驱动。
|
||
- **供电:** 3.0–3.6V, 推荐 3.3V.
|
||
- **Deep-sleep:** ~7 µA.
|
||
- **工作温度:** −40°C ~ +85°C（可扩展到 +105°C）.
|
||
- **封装:** QFN40 (5×5mm) 或 QFN32 (5×5mm).
|
||
|
||
