The QCA4531 from Qualcomm is a two-stream (2x2) 802.11b/g/n single-band programmable Wi-Fi SoC with a channel bandwidth of 20 and 40 MHz. It has a powerful MIPS 24Kc CPU core that operates at a 650 MHz clock rate. This Wi-Fi SoC supports open-source Linux, Embeds OpenWrt networking, and open-source Wi-Fi drivers for simplifying software development. It is designed to operate as an IoT access point, supporting up to 16 simultaneous devices, and is power-optimized to allow appliances to meet international standards for energy efficiency.

This Wi-Fi SoC module has an integrated PA that produces an output power of  20 dBm, integrated LNA, and requires an external power source of 3.3V. It has an external 16-bit DDR1, operating at up to 200 MHz and DDR2 operating at up to 300 MHz with a transfer rate of up to 600 M transfers/sec. This Wi-Fi SoC has an I2C interface for connecting digital sensors and the Apple HomeKit MFi chip and supports HTTP, IPv4v6, TCP, SSL, DHCP, ICMP, IGMP, and DNS protocols. It contains interfaces that will allow attachment of Bluetooth/802.15.4/Z-Wave radios and has software support for Google Weave, Open Connectivity Foundation, and AllJoyn from the AllSeen Alliance.

To address fragmentation in the IoT, this SoC supports multiple application-layer interoperability standards, allowing products to connect across different brands and platforms. It is available in a 12 x 12 mm QFN package and has a wide industrial operating temperature range of -40 to 85 degrees Celsius. This low-cost turnkey solution combines high-performance connectivity capabilities and is ideal for Energy Management, Smart Home, Wi-Fi Repeater, Smart Appliances, Residential Lighting, and IoT Gateway applications.
