特性

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
  - Packet engine with CRC, AES-128 encryption and 66-byte FIFO
  - 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
