Espressif announces the ESP32-H2, an IEEE 802.15.4 and Bluetooth 5.2 (LE) RISC-V SoC

The ESP32-H2 features an integrated IEEE 802.15.4 transceiver and Bluetooth 5.2 (LE) connectivity, as well as a 32-bit RISC-V core. This enables low power consumption and security for networked devices.

Espressif Systems (Shanghai) Co., Ltd. (SSE: 688018.SH) today introduced its new ESP32-H2 SoC with IEEE 802.15.4 and Blue tooth 5.2 (LE) connectivity in the 2.4 GHz band. The ESP32-H2 expands Espressif's portfolio beyond Wi-Fi and Bluetooth and adds IEEE 802.15.4 connectivity. This SoC comes with an integrated DC-DC converter that enables ultra-low power, energy-efficient operation. Espressif is very st olud to mention that the Bluetooth 5.2 subsystem was developed exclusively by its own engineering team.

ESP32-H2 combines two important ve rnetting technologies. IEEE 802.15.4 radio connectivity is important to support low-power mesh architecture, and the availability of threaded and ZigBee protocols addresses a variety of use cases. Bl uetooth LE supports point-to-point, broadcast and mesh communication topologies, but also enables direct communication between smartphone and device.

In addition, the ESP32-H2 leverages Bluetooth 5.2 technology and with its new features such as isochronous LE channels, which allows devices to be built for LE audio, the next generation of Bluetooth audio. LE audio not only improves Bluetooth audio performance, s ondern also provides support for audio transmission and audio sharing activation. Bluetooth 5.2's LE Power Control and Enhanced Attribute Protocol also further improve device efficiency. The ESP32-H2 also offers full support for the Bluetooth Mesh protocol and the upcoming Bluetooth Mesh 1.1.

The combined availability of IEEE 802.15.4 and Bluetooth LE connectivity enables the development of devices for the upcoming Matter protocol, which is expected to bring interoperability to smart home devices. With ESP32-H2 and other SoCs in its portfolio, Espressif can offer the full spectrum of Matter protocol solutions for endpoints with Wi-Fi or threaded connectivity, as well as for border router implementations with a combination of SoCs.

The ESP32-H2 features a single-core 32-bit RISC-V microcontroller that can be clocked at up to 96 MHz. It has 256 KB of SRAM and operates with external flash. It has 26 programmable GPIOs with support for ADC, SPI, UART, I2C, I2S, RMT, GDMA and PWM. Ed he SP32-H2 further facilitates the building of secure networked devices through hardware security features such as ECC-ba- sed secure boot, AES-128/256-XTS-based flash encryption, digital signature and an HMAC peripheral for identity protection, and cryptographic accelerators for improved performance.

The ESP32-H2 supports Thread version 1.x as well as ZigBee 3.x. Espressif, as an active member of the CSA, will continue to develop and support the Matter protocol on ESP32-H2 as the standard progresses. The ESP32-H2 is accompanied on the software side by Espressif's mature IoT Development Framework (ESP-IDF), so developers can benefit from their familiarity with this field-proven platform, which is already in use in millions of networked devices.
