The Kinetis KW0x wireless MCU family embeds a rich set of peripherals with a high-performance bi-directional sub-1 GHz radio, capable of operating over a wide frequency range in the license free industrial, scientific and medical (ISM) frequency bands. Integrates high-performance, low-noise amplifiers and power amplifiers Runs various types of communication protocols, from proprietary (simple media access controller (SMAC)) to globally standardized (IEEE 802.15.4) Includes hardware, software, tools and reference designs to help simplify development
RF Transceiver
- Supports 290-340 MHz, 424-510 MHz, and 862-1020 MHz frequency bands
- High sensitivity: down to -120 dBm at 1.2 kbps
- High selectivity: 80 dB blocking immunity
- Low current: Rx = 16 mA
- Programmable output: -18 to +17 dBm in 1 dB steps
- FSK bit rates up to 600 kbps
- 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 closest8/16-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 3.6 V 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 (<10>
- Supports point-to-point communication (bi-directional RF communication link), broadcast communication
