Espressif Systems today announced that the ESP32-C61 has officially entered full-scale mass production. This high-connectivity, cost-effective SoC integrates 2.4 GHz Wi-Fi 6 and Bluetooth 5 (LE), specifically designed to meet the dual demands of high-speed connectivity and low power consumption for next-generation smart devices.
The ESP32-C61 supports 2.4 GHz Wi-Fi 6 and Bluetooth 5 (LE), featuring uplink and downlink OFDMA access and downlink MU-MIMO, while offering Target Wake Time (TWT) functionality. It delivers low-latency, high-concurrency wireless performance, ensuring stable communication even in complex network environments. Bluetooth 5 (LE) supports extended advertising, Coded PHY, and 2 Mbps PHY, enabling long-range and high-speed communication. It is also compatible with Bluetooth Mesh 1.1, meeting diverse IoT connectivity requirements.
The chip is powered by a single-core 32-bit RISC-V processor with a maximum frequency of 160 MHz, integrating 320 KB SRAM and 256 KB ROM, and supports Quad SPI Flash and stacked PSRAM (Quad SPI up to 120 MHz), fully satisfying data processing and caching needs. In addition to standard peripheral interfaces such as I2C, I2S, SPI, UART, LEDC, ADC, and GDMA, the ESP32-C61 introduces an Event Task Matrix (ETM) and Analog Voltage Comparator, offering higher integration and flexibility for automation control and power equipment applications.
ESP32-C61 features a comprehensive hardware security system, supporting secure boot, Flash/PSRAM encryption, RSA/AES/SHA acceleration engines, and ECDSA digital signature modules. Combined with Access Permission Management (APM) and Physical Memory Protection (PMP), it creates a Trusted Execution Environment (TEE) to effectively prevent unauthorized access to critical data.
Software support for the ESP32-C61 is provided by Espressif’s mature ESP-IDF IoT development framework, and it is also compatible with ESP-Matter SDK. Additionally, users can leverage Espressif ESP-Hosted and ESP-AT to use the ESP32-C61 as a co-processor for external hosts, further expanding its application scenarios.
