The Kinetis W series is optimized for wireless, providing the right mix of performance, integration, connectivity and security. The enablement packages include NXP'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.

Features

  • KW0x Features
    • RF Transceiver
      • Supports 290-340MHz, 424-510MHz, and 862-1020MHz frequency bands
      • High sensitivity: down to -120dBm at 1.2kbps
      • High selectivity: 80dB blocking immunity
      • Low current: Rx = 16mA
      • Programmable output: -18 to +17dBm in 1dB steps
      • FSK bit rates up to 600kbps
      • FSK, GFSK, MSK, GMSK and OOK modulations

      • Built-in temperature sensor and low battery indicator
    • MCU
      • Ultra-low-power 32-bit ARM® Cortex®-M0+ core. 2x more CoreMark/mA than the closest 8/16-bit architecture. Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, maintaining an 8-bit "look and feel"
      • Multiple, flexible low-power modes including new compute mode which reduces dynamic power by placing peripherals in an asynchronous stop mode
      • I2C, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core
    • Memory
      • 128 KB flash with 64 byte flash cache
      • 16 KB RAM
    • Peripherals
      • 16-bit ADC with configurable resolution, sample time and conversion speed/power
      • High-speed comparator with internal 6-bit DAC
      • 12-bit DAC with DMA support
    • Interfaces
      • Capacitive touch sense interface supports external electrodes
      • GPIO with pin interrupt support, DMA request capability and other pin control options
      • One I2C with DMA support, up to 100Kbps and compatible with MBus V2 features
      • 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
