87-YB662-1 Rev C
The QCA4531 is a two stream (2x2)
802.11b/g/n single-band programmable
Wi-Fi System-on-Chip (SoC) for the IoT. This
low-cost turnkey solution combines high-
performance connectivity capabilities
with a user-programmable Linux
OpenWrt environment and is designed
to serve either as a feature-rich IoT node
or as a hub to support an IoT ecosystem.
The QCA4531 is a single-chip access point
SoC designed to deliver a high-performance
2x2 802.11b/g/n solution, as well as a powerful
MIPS 24Kc CPU core that operates at up to
a 650MHz clock rate. This system runs open
source Linux and the OpenWrt networking
stack, to help with ease of development.
The QCA4531 includes a communications
stack, including HTTP, IPv4v6, TCP, SSL,
DHCP, ICMP, IGMP, and DNS. 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 eciency.
To address fragmentation in the IoT, the
QCA4531 supports multiple application
layer interoperability standards, allowing
products to connect across dierent brands
and platforms. The QCA4531 is ideal for IoT
hubs that bridge from other IoT connectivity
technologies like Bluetooth, 802.15.4 (ZigBee/
Thread) and Z-Wave to the home Wi-Fi
network. It contains interfaces that allow
attachment of Bluetooth/802.15.4/Z-Wave
radios, plus the Linux environment supports
the development of bridging soware.
