IMG iEW 400 Series

Ensigma Wi-Fi Connectivity Family

IEEE 802.11ax Wi-Fi

The iEW400 Series is the latest addition to our growing list of Wi-Fi IPs, supporting the IEEE802.11ax (Wi-Fi 6) 20/40MHz and operating in both 2.4/5 GHz band. The iEW400 Series supports advanced IEEE802.11ax features such as Target Wake Time (TWT), OFDMA, and BSS coloring. Our single source IP solution provides the benefits of being highly integrated, resulting in system-level minimal eBOM cost. Optional UMAC and PMU are also available.
