ESP32-E22 – the new Wi-Fi 6E connectivity standard for IoT
Espressif has introduced the ESP32-E22 – the first SoC in its portfolio supporting the Wi-Fi 6E standard in the 2.4 GHz, 5 GHz, and 6 GHz bands, as well as Bluetooth Classic and Bluetooth Low Energy. The new chip has been designed as a high-performance communication co-processor intended to enable the development of modern IoT devices, consumer electronics, and industrial solutions requiring fast and reliable wireless connectivity.
Tri-band Wi-Fi 6E and high transmission performance
The ESP32-E22 offers tri-band Wi-Fi 6E connectivity operating in the 2.4 GHz, 5 GHz, and 6 GHz bands, allowing the use of less congested transmission channels and enabling higher throughput and lower latency. The chip supports channel bandwidth up to 160 MHz, 2×2 MU-MIMO technology, beamforming, and advanced transmission management mechanisms, ensuring stable operation even in environments with a high number of wireless devices. The use of 1024-QAM modulation allows data transfer speeds of up to 2.4 Gb/s.
Bluetooth integration and radio co-processor architecture
The new chip also integrates a Bluetooth Classic (BR/EDR) controller and Bluetooth Low Energy 5.4, enabling interoperability with both modern and legacy devices. The ESP32-E22 operates as a Radio Co-Processor, handling the entire communication stack, including security mechanisms, authentication, network scanning, and roaming. This approach offloads the main device processor, allowing it to focus on application-level functions. The chip can work with both Espressif processors and third-party solutions via high-speed interfaces such as PCIe 2.1 and SDIO 3.0.
A versatile platform for IoT and industry
At the core of the ESP32-E22 is an Espressif-developed dual-core RISC-V processor operating at 500 MHz, providing sufficient computing power to support advanced communication features and networking protocols. The chip has been designed as a universal wireless platform that can be used in applications such as high-bandwidth video streaming systems, smart home hubs, IoT devices, household appliances, industrial automation systems, and AR/VR accessories requiring low-latency communication. The manufacturer also emphasizes long-term technical support and the continued development of its in-house RISC-V architecture, while engineering samples of the chip are already available to hardware manufacturers.
