Solution Highlights

QCA400x is an intelligent Wi-Fi platform

for the Internet of Things (IoT). This

complete networking platform enables

customers to add full-featured Wi-Fi to

a wide variety of products with minimal

development effort and cost.

QCA400x is a single-stream (1x1) IEEE 802.11n

single-band (QCA4002) or dual-band (QCA4004)

System-on-Chip (SoC) or module solution for the

Internet of Things (IoT). The highly integrated Wi-Fi

link includes an energy efficient on-board power

amplifier and LNA. For the 2.4GHz band, RF switches

are also integrated. The QCA400x is optimized

for low system cost, and minimizes the number of

components required to achieve a reliable Wi-Fi

link. In addition, the QCA4004 can operate in a pure

hostless mode of operation.

The QCA400x platform provides two host interfaces

for connecting to local system controllers. A

UART-based host interface can be used for rapid

development and deployment of simple data streams

between the local device and the internet cloud.

An SPI slave interface is available for applications

that require more advanced connectivity to the

network. It supports a network stack along with SSL

security, enabling full-featured internet connectivity

and reliable information exchange in a small, low-

cost system. It supports the AllJoyn™ connectivity

software framework and services, allowing devices

to discover, connect and communicate directly with

one another.

Power saving Wi-Fi modes

extend battery life

Supports power saving modes and Quad SPI flash for

faster wake time which minimizes power consumption and

extends battery life.

On-board wake-up manager to

further reduce sleep power

The onboard wake-up manager enables self-wake and

sleep management on the QCA400x platform which can

further reduce sleep power (down to microamps).

On-chip user development for

hostless applications

Developers can write simple applications directly on the

QCA4004, eliminating the need for a standalone MCU.

Dual-band support for more

robust Wi-Fi connection

QCA4004 with dual-band connectivity for both

2.4GHz and 5GHz is well-suited for applications in

interference sensitive environments.

Qualcomm Wi-Fi Solutions, QCA4002 and QCA4004 are products of Qualcomm Technologies, Inc.
