Silex Enables Plug-n-Play Wi-Fi for the NXP i.MX RT Crossover Processors

10 December 2018

SANTA ANA, Calif., Nov. 7, 2018 /PRNewswire/ -- Silex Technology, Inc., a global leader in wired and wireless networking solutions, today released the FreeRTOS wireless driver for its SX-SDMAC "Smart-Ready" SDIO module based on the Qualcomm® QCA9377 chip. The SX-SDMAC is a wireless connectivity solution designed to deliver superior integration of wireless local area network (WLAN) and Bluetooth low-energy technology – engineered to support 1 × 1 802.11a/b/g/n/ac Wi-Fi and Bluetooth 4.2 + HS. This release offers "Plug-n-Play" solution allowing manufacturers to easily add Wi-Fi and Bluetooth capability to their NXP's i.MX RT based devices.  


"Robust connectivity is at the core of any IoT solution, and with this announcement, Silex is taking an important step to support developers with the Wi-Fi and Bluetooth options they need to quickly and cost-effectively create new and exciting applications," said Joseph Bousaba, vice president, product management, Qualcomm Technologies, Inc. "We are excited to build on our long-standing relationship with Silex to scale up channel distribution for our technologies and enable end customers with superior connectivity."

NXP® i.MX RT crossover processors bridge the gap between microcontrollers (MCU) and applications processors. These processors bring applications processor-level performance into the MCU world to support real-time, performance-intensive processing functions. Silex offers hardware and software for users to easily add 802.11ac wireless connectivity to i.MX RT devices that require high performance for their target applications.

"By adding Wireless support to the i.MX RT Series, Silex now opens the doors for embedded developers using i.MX RT to add 802.11ac Wi-Fi connectivity easily," said Joe Yu, vice president and general manager, Low-Power MPU and LPC MCU Product Lines at NXP Semiconductors. "We have partnered with Silex Technology to bring Wi-Fi solutions for the i.MX RT series because of their track record of creating highly reliable embedded Wi-Fi technology and the proven support they offer to NXP customers."


Dual-band 802.11ac + Bluetooth SDIO module delivering enterprise-grade Wi-Fi connectivity with link rates as high as 433 Mbps. It is easy to integrate and supports multiple software driver options including FreeRTOS for the i.MX RT series.

SX-SDMAC Features:  

  • Based on the QCA9377 chip
  • IEEE 802.11a/b/g/n/ac Wave 2 MU-MIMO Client
  • SDIO 3.0 WLAN host interface
  • Bluetooth 4.2 BR/EDR/LE Smart Ready
  • Link rate of up to 433 Mbps
  • Driver support included
  • Support for enterprise security, seamless roaming

In addition to the SX-SDMAC, Silex Technology offers SPI interface based single-band and dual-band Wi-Fi radios in the SX-ULPAN. SX-ULPAN is a lower cost option, based on the Qualcomm® QCA4004 dual-band 802.11n SoC, which may be suitable for typical IoT sensory applications that are low power.

The SX-ULPAN is an ultra-low-power Wi-Fi module available as either a single band or dual-band 802.11n module and available with industrial temperature support. This low power Wi-Fi module is based on the QCA4004 SoC from Qualcomm Technologies, Inc. SPI interface drivers for SX-ULPAN are built into the i.MX RT SDK.

SX-ULPAN Features:

  • Ultra-low-power module features QCA4004 SoC
  • Single or Dual-Band 802.11n
  • Supports SPI/UART as Host interface
  • Driver support included in NXP BSP
  • Industrial Temperature range support
  • Hardware Supports Security- WPS, WPA and WPA2
  • Ideal for Low Power IoT applications
  • Onboard Antenna & U.FL Connector Add-on

To expedite the product development process, Silex also provides additional world-class engineering services including custom driver development, certification services, and hardware schematic design reviews.
