Product Overview 

The  XR-50B  WiFi  module  was  developed  to  meet  the  IOT  application  of  speech 

recognition, consisting of the core processor XR872, AC107 audio CODEC , power supply and 

auxiliary  circuit.  The  XR872  integrates  ARM-M4F  MCU  and  high-capacity  SRAM  in  a  smaller 

package with operating frequency up to 384MHz. The XR872 is a highly integrated low-power 

Wi-Fi  microcontroller  SoC  that  integrates  Wi-Fi  MAC/BB/RF/PA/LNA,  high-performance  and 

highly  integrated  MCUs,  enabling  software  to  perform  more  complex  tasks  and  support 

hardware  encryption  engines  such  as  AES/DES/3DES/SHA/MD5/CRC  to  make  data 

transmission  more  secure  and  faster.  The  new  digital  RF  transmitter,  designed  with 

XRADIOTECH's  MPDTM  technology,  provides  higher  output  power  and  maintains  higher 

efficiency,  keeping  the  chip  insensitive  to  antenna  mismatches,  but  always  has  a  good  EVM 

under  different  VSWR.  It  also  includes  a  number  of  peripherals,  including  UART,  TWI,  SPI, 

DMIC, Audio Codec, PWM, CIR (T/R), CSI, SDIO and Auxiliary ADC. 

The XR-50B WiFi module supports the standard IEEE802.11 b/g/n protocol, RTOS, and has 

a complete TCP/IP protocol stack. Users can use the module to add networking capabilities to 

existing devices, or they can use it to build separate network controllers. Built-in high-speed 

buffer memory improves system performance and reduces memory requirements
