Pretty standard to use ATWINC1500, CYW43439, ESP8266, or ESP32 to add Wifi over UART/SPI/i2c to another microcontrol chip.

This is done with the RP Pico W, Adafruit Feather M0 Wifi / or Airlift, 3d Printer boards (Duet Wifi) and allows you to add Wifi to code bases already written for these boards without worrying about rewriting and/or hitting memory performance issues with running Wifi and logic on a single chip.

Not to mention having your interface chip not be what you're organizing increases reliably and prevents bricking
