Wireless Transceivers For Home And Industrial Automations


To meet the rising market demand for home automation and industrial control applications, Freescale unveiled its new MCUs which extends wireless capabilities for automation. The newly launched Kinetis MCR20AVHM features a wireless transceivers with dual PAN functionality.  It also enables communication with multiple networks via a single radio, as well as antenna diversity for robust RF performance in harsh environments.

According to the media release, “The MCR20AVHM transceiver is a low-power, high-performance 2.4 GHz, IEEE 802.15.4 compliant transceiver with connectivity to a broad range of microcontrollers, including the Kinetis family of products. The MCR20AVHM transceiver (throughout this document called MCR20A) enables development of proprietary and standard 802.15.4 based communication protocols such as SMAC, IEEE802.15.4 PHY-MAC, Thread, ZigBeePRO, RF4CE, and others.” Further, the release lays emphasis on the tool stating, “Customers can leverage Freescale’s Freedom development kit for the MCR20AVHM and connect it to the Kinetis KL46 and K64F Freedom boards for a full development system. Enablement support for the MCR20AVHM includes a compliant IEEE 802.15.4-2011 PHY-MAC implementation based on the existing Kinetis Software Development Kit (SDK), which enables portability to other Kinetis devices beyond the initially targeted KL46 and K64F microcontrollers.”

The MCR20AVHM transceiver features as listed below:

  • Hardware acceleration for IEEE 802.15.4 2006 packet processing
  • Support for Dual PAN mode
  • Onboard trim of reference crystal
  • 128-byte RAM data buffer
  • Low-power operating modes with single SPI command device wake-up
  • On-chip voltage regulators
  • Clear Channel Assessment, Energy Detect, Link Quality Indicator
