Freescale Kinetis W MCUs

Freescale Kinetis W MCUs

Freescale's Kinetis W Microcontrollers integrate class-leading sub-1 GHz and 2.4 GHz RF transceivers with ARM® Cortex® cores, providing robust feature sets for reliable, secure and low-power embedded wireless solutions. The Kinetis W series is optimized for wireless, providing the right mix of performance, integration, connectivity and security. The enablement packages include Freescale's Tower System Development Platforms, MQX™ RTOS and support from IAR Systems. Whether you need sub-1 GHz or 2.4 GHz wireless, simple point-to-point or full mesh networking, the Kinetis W series has the solution to fit your needs.

Freescale's KW0x Kinetis Microcontrollers are ultra-low-power wireless MCUs that are an ARM® Cortex®-based smart radio solution designed for sub-1 GHz (290-1020 MHz) wireless connectivity applications. Powered by the ultra-low-power 48 MHz ARM Cortex-M0+ 32-bit MCU, the MKW01 embeds a rich set of peripherals with a high-performance bi-directional sub-1 GHz radio, capable of operating over a wide frequency range including 315, 433, 470, 868, 915, 928 and 960 MHz in the license free industrial, scientific and medical (ISM) frequency bands.

  • One LPUART and two UART with DMA support

Operating Voltage and Temperature Range
  • 1.8 to 3.6V operating voltage with on-chip voltage regulators
  • Temperature range of -40°C to +85°C
Software
  • Radio Test Tool
  • Run on PC connected through USB
  • Allow fast evaluation of the radio performance in a lab environment without need for writing software
  • Analysis of TX spectrum (output power, harmonics)
  • Modulation scheme impact (GFSK, BT, Mod index) on spectrum
  • Help on matching network tuning
  • Analysis of RX Sensitivity performance (RSSI, LNA input impedance, OOK threshold, AFC)
  • SMAC (Simple Media Access Controller)
  • Simple communication and test apps based on drivers/PHY utilities available as source code
  • Small footprint (<10KB)
  • Supports point-to-point and star networks with repeaters
  • Support for over-the-air programming
Applications

Freescale Kinetis KW2x wireless MCU expands the successful Kinetis MCU family based on the ARM Cortex-M4 CPU core. The Kinetis KW2x integrates a class-leading 2.4 GHz RF transceiver, ARM Cortex-M4 core and a robust feature set for a reliable, secure and low-power IEEE 802.15.4 wireless solution. 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 ZigBee networks, eliminating the need for multiple radios. Software protocol stacks, tools and IDE are compatible with Kinetis MCUs. ZigBee protocol software is seamlessly integrated into Kinetis software development tools for rapid creation of embedded systems. Typical applications include Home Area Networks consisting of meters, gateways, in-home displays, and connected appliances, and also networked Building Control and Home Automation applications with lighting control, HVAC, and security.
