QCA4020

QCA4020

Multi-mode intelligent connectivity solution integrating dual-band Wi-Fi, Bluetooth 5 and 802.15.4 technology.

The QCA4020 SoC is a multi-mode system-on-chip with support for dual-band Wi-Fi, Bluetooth 5 and 802.15.4-based technologies, including Zigbee and Thread.

This low power SOC integrates a Cortex M4F for application processing, Cortex M0 for network stack processing, and a separate processor for Wi-Fi stack designed to enable a highly concurrent multiple radio solution.

The QCA4020 SDK from Qualcomm Technologies pre-integrates support for advanced security features and multiple software / cloud ecosystems.

Designed to address IoT fragmentation and support for interoperability, this solution is ideal for multiple IoT industries from home control and automation, networking, home entertainment and smart cities.

Qualcomm Mesh, CSRmesh, Qualcomm Trusted Execution Environment and QCA4020 are products of Qualcomm Technologies, Inc. and/or its subsidiaries.
