1. Product Overview

XR-31B WiFi module was developed for a wide range of IoT applications, Its core processor XR808

integrated the ARM Cortex-M4F 32-bit microcontroller in a smaller package, supporting the master clock

frequency up to 160MHz; Integrated high-performance WLAN system with Wi-Fi MAC/BB/RF/PA/LNA units;

Integrated advanced power management units for ultra-low power consumption with multiple sleep modes

and fast wake-up mechanisms; Integrated hardware encryption engine to supports AES/DES/3DES/SHA-1/

MD5/ CRC/ SHA256/TRNG; Integrated large memory and rich peripherals.

XR-31B WiFi module supports standard IEEE802.11 b/g/n protocol, supports RTOS, with a complete

TCP/IP protocol stack, Users can use the module to add networking capabilities to existing devices, or can

use it as a master design wireless network product, XR808 can be started directly from external flash

memory, the on-chip high-speed buffer memory helps improve system performance and reduce RAM

requirements.
