乐鑫信息科技于2025年4月30日宣布ESP32-C5芯片正式量产。这是业界首款支持双频Wi-Fi 6（2.4GHz和5GHz）、蓝牙5（LE）和IEEE 802.15.4（Zigbee、Thread）的RISC-V系统级芯片。ESP32-C5专为高效、低延迟无线传输而设计，其核心部件包括一颗240MHz主频的32位单核处理器，384KB SRAM，支持外部PSRAM，以及320KB ROM。它提供多达29个可编程GPIO，常见的外设，高速接口（SDIO、QSPI）和高级安全特性。此外，一个运行频率为40MHz的低功耗CPU则可用于对功耗敏感的应用。ESP32-C5支持乐鑫的ESP-IDF框架（v5.5版本开始初步支持），并可通过ESP-AT或ESP-Hosted方案作为连接协处理器。开发者板现已通过乐鑫官方商店发售。

Hacker News 的讨论围绕着乐鑫 ESP32-C5 的量产发布展开，这款基于 RISC-V 架构的微控制器支持双频 Wi-Fi 6、蓝牙 5 和 Zigbee/Thread。用户们对 5GHz 支持和 Zigbee 集成（尤其用于电池供电设备）表示兴奋。一些人提到了 ESP32-C6 也支持 Zigbee，尽管价格略高。 人们也表达了对 ESP-IDF 的 BSD 系统易用性以及与 nRF 芯片相比的功耗的担忧。用户还讨论了缺乏对非引导协议设备的 USB Host HID 类驱动程序支持。开发套件的内存容量也得到澄清，为 384KB RAM 和 8MB Flash。 从 Xtensa 架构转向 RISC-V 的转变也引发了辩论，一些人强调 RISC-V 拥有更好的编译器支持和更低的授权成本，而另一些人则指出潜在的性能缺陷。一些人对 C5 的单核设计表示失望。AliExpress 上开发板的价格和供货情况也被提及。

    Today, we are glad to announce that ESP32-C5 is now in mass production.

    Espressif Systems (SSE: 688018.SH) announced ESP32-C5, the industry’s first RISC-V SoC that supports 2.4 GHz and 5 GHz dual-band Wi-Fi 6, along with Bluetooth 5 (LE) and IEEE 802.15.4 (Zigbee, Thread) connectivity. Today, we are glad to announce that ESP32-C5  is now in mass production.

    ESP32-C5 is designed for applications that require high-efficiency, low-latency wireless transmission. ESP32-C5 has a 32-bit single-core processor which can clock up to 240 MHz in speed. It has a 384 KB on-chip SRAM along with external PSRAM support, 320 KB of ROM. It has up to 29 programmable GPIOs, supporting all the commonly used peripherals, high speed interfaces like SDIO, QSPI, and the best-in-class security features. The ESP32-C5 also includes an LP-CPU running upto 40MHz which can act as the main processor for power sensitive applications. To learn more about the various capabilities and features of this MCU, please visit our website.

    The ESP32-C5 benefits from software support provided by Espressif's well-established IoT development framework, ESP-IDF. The upcoming ESP-IDF v5.5, will include initial support for the ESP32-C5. For a detailed list of ESP-IDF features supported for the ESP32-C5, click here. The ESP32-C5 can also act as the connectivity coprocessor for external hosts using the ESP-AT or ESP-Hosted solutions.

    ESP32-C5 development boards are now available for purchase at Espressif's official stores If you are interested in the ESP32-C5 series products, please contact our customer support team.
