The ultimate Wi-Fi
solution for
low-power IoT

From weather sensors to wearables, to connected toys and hearing aids, battery-driven devices of all types require internet connectivity. That means, energy-efficient, low-power solutions.

Introducing IMG iEW400, the ultimate Wi-Fi solution for low-power IoT devices. Based on the new IEEE 802.11ax standard, Wi-Fi 6 offers several enhancements over its Wi-Fi 5-based predecessor to boost efficiency and reduce power consumption, making it ideal for low-power IoT wireless applications.

Wi-Fi 6: Built-in efficiency

iEW400 takes advantage of key Wi-Fi 6 features to save device power and help you build a more useful Wi-Fi product.

Smart design

Target Wake Time (TWT) is a new Wi-Fi 6 feature that negotiates when access points and devices should be “awake”. This pre-scheduling means devices don’t have to waste energy waiting to communicate with an access point. Device deep-sleep periods can be extended, dramatically reducing current consumption and significantly increasing battery life. This means Wi-Fi 6 devices can now be left usefully gathering data in the field for years at a time!

Improved performance
for all

Orthogonal frequency-division multiple access (OFDMA) improves performance in high-density environments. By enabling bandwidth within channels to be segmented, multiple devices can receive data in the same time frame. This increases data transmission efficiency, reducing power consumption and dramatically increasing data throughput.

A world of colour

In areas where there are multiple access points and many clients, such as large crowds, Wi-Fi typically struggles to deliver consistent throughput. This is because the data from different access points can overlap causing contention and interference. With the new Basic Service Set (BSS) Coloring feature in Wi-Fi 6 each data from each access point is prescribed a “colour”, so clients can identify which one is transmitting. The result is improved network performance for IoT and wireless.

The complete low-power Wi-Fi solution

iEW400 is a complete,
one-stop-shop solution. It includes the RF, Baseband, upper and lower MAC components, internal power amplifiers, LNA and switch and sleep controller.

Flexible design

Flexible design tailored to your requirements with optional upper MAC and power management unit (PMU) supporting 2.7-4.5V DC supplies.

Lowarea

Low area, silicon-ready IoT solution

In TSMC 40nm LP iEW400 has a low silicon die area of 6.84 mm2 die area, including analogue pads. Supplied as hard macro for analogue and synthesisable RTL for digital.
