Espressif Systems launches the ESP32-E22, marking its entry into Wi-Fi 6E technology with a dedicated radio coprocessor for advanced wireless designs. This chip offloads complex networking tasks, freeing main processors for core functions in IoT and edge devices.
Key Technical Specs
- The ESP32-E22 with radio coprocessor packs dual RISC-V cores at 500 MHz, handling full Wi-Fi 6E and Bluetooth stacks independently.
- It supports tri-band operation across 2.4 GHz, 5 GHz, and 6 GHz frequencies, with 160 MHz channels, 2×2 MU-MIMO, beamforming, and up to 2.4 Gbps throughput via 1024-QAM modulation.
- Bluetooth 5.4 covers both Low Energy and Classic modes (BR/EDR), aided by coexistence tech for simultaneous radio use.
Connectivity Options
Designers connect it to hosts via PCIe 2.1 or SDIO 3.0 interfaces, ideal for pairing with Espressif or third-party SoCs. Internal management covers security, scanning, roaming, and authentication, simplifying integration.
The ESP32-E22, first Wi-Fi 6E-based communications coprocessor, is the latest addition to the ESP32 microcontroller family.
Target Applications
Engineers target it for high-data streaming, smart home gateways, industrial bridges, and low-latency AR/VR gear in crowded networks.
