Freescale Kinetis W KW2x MCU Family


Freescale's Kinetis W series of MCUs is optimized for low-power wireless communication

Freescale's Kinetis KW2x wireless MCUs expand on the successful Kinetis MCU family based on the ARM® Cortex™-M4 CPU core. The Kinetis KW2x wireless MCU integrates a class-leading RF transceiver, Cortex-M4 and a robust feature set for reliable, secure, and low-power IEEE® 802.15.4 wireless solutions. These wireless MCUs offer up to 512 KB of Flash, 64 KB of RAM, and up to 64 KB of FlexMemory. Dual-PAN support allows the system to simultaneously participate in two 802.15.4 networks, eliminating the need for multiple radios. Software protocol stacks, tools, and IDE are compatible with Kinetis MCUs. Kinetis KW2x devices provides best-in-class RF features compatible with Freescale’s Kinetis Cortex-M4 MCUs to provide the industry’s most capable 802.15.4/ZigBee platform.

Features
  • RF (sensitivity) performance – range-Highest Sensitivity (110dB) for maximum range
  • Large memory – more nodes, future proof (Future specifications for ZigBee and IP protocol stacks are requiring increased processing and memory requirements from existing embedded applications)
  • Integrated security – important to IoT
  • Dual-PAN hardware integrated – multiple network capable
Applications
  • Boiler heating controls
  • Remote controls
  • Activity and wellness monitors
  • Access and remote controls
  • Thermostats
  • Smart grid and smart metering
  • Building controls
