Wi-Fi Standalone

Microchip’s SAMW25 is a standalone IoT solution with both a microcontroller and Wi-Fi SoC in one complete module package. The SAMW25 uses the SAMD21 ARM® Cortex®-M0+ MCU to run the host application. The SAMD21 MCU includes the API and an SPI driver for interfacing to the onboard Wi-Fi SoC. The Wi-Fi SoC is Microchip’s ultra-low power WINC1500, an IEEE 802.11 b/g/n IoT network controller with integrated TCP/IP and Wi-Fi stack.


SAMW25 Key Features

  • Fully-certified IEEE 802.11 b/g/n Wi-Fi module
  • WINC1500 Wi-Fi SoC plus SAMD21 ARM Cortex-M0+ based MCU
  • Integrated PA and T/R switch
  • Wi-Fi Direct, station mode and SoftAP support
  • Supports IEEE 802.11 WEP, WPA
  • 4 Mbit internal Flash memory with OTA firmware upgrade
  • SPI, UART and I2C as host interfaces
  • TCP/IP protocol stack (client/server) sockets applications
  • Network protocols (DHCP/DNS), including secure TLS stack
  • Can operate completely host-less in most applications
