Hello @patangera, hope you are doing well.
For Wi-Fi hostless MCUs we only provide the RW61X Family, however this is a big MCU capable of supporting Wi-Fi, BLE and 802.15.4 (this protocol is not supported on RW610), and it may not fit your requirements. I would suggest checking our Wi-Fi hosted ICs, such as IW611 that can interface with an MCU to run Wi-Fi features.
Hope this helps, and please let me know if you are interested in any of our hosted ICs. If this is the case, please provide more details of your application so I can share a more suitable recommendation.
Best Regards!
