XW71-WiFi 1. Product overview The XW71N WiFi module is a complete BLE5.1+ WiFi network solution that can operate independently or as a slave to other host MCUs. The module can be booted directly from the built-in Flash when equipped with external applications and acting as the only application processor in the device; it also contains a low-power ARMCM4 MCU, 1T1R WLAN, up to 120MHz, built-in 256K SRAM, 2Mbyte flash and rich peripheral resources. The XW71N WiFi module supports the IEEE 802.
