IoT IP integrates RF and baseband for 802.11ax – Wi-Fi 6

Author: EIS Release Date: Jun 16, 2020


Imagination ‘s latest IP delivers  integrated RF and baseband, designed for low-power and battery-powered applications such as the IoT, wearables and hearables.

iEW400 is based on the latest IEEE 802.11ax Wi-Fi 6 standard, bringing improved robustness, throughput and power-saving through a range of new features, including:

  • 20/40MHz operation: Enables low-data-rate applications to conserve battery power
  • Target Wake Time (TWT): Extends deep-sleep periods, dramatically improving current consumption and extending battery life
  • Orthogonal frequency-division multiple access (OFDMA): Enables bandwidth to be segmented for the efficient transmission of data, reducing power consumption, whilst improving robustness and data throughput
  • Basic Service Set (BSS) Coloring: Increases robustness in dense environments, enabling improved data throughput
  • Dual sub-carrier modulation (DCM): Enables increased robustness for low data rates
  • Optional upper MAC available to offload work from the host processor to reduce total system power consumption
  • Optional power management unit (PMU) supporting 2.7-4.5V DC supply optimised for low-power

iEW400 is a complete, ready-to-market solution that includes integrated RF, AFE, baseband PHY and MAC. It is supplied as hard macro for analogue and synthesisable RTL for digital, enabling maximum flexibility and the fastest time to market along with reduced development costs.

iEW400 is available for licensing now. Key features include:

  • Complete 2.4/5GHz low-power Wi-Fi solution
  • Silicon-ready design, with a 6.84 mm2 die area, including analogue pads, in TSMC 40nm LP
  • Internal power amplifiers, LNA and switch
  • Sleep controller to ensure overall system-level power consumption reduction
  • Optional integrated power management unit (PMU)
  • Supports Station, Soft AP and Wi-Fi Direct operating modes
