KW0x: Kinetis® KW0x-48 MHz, Sub-1 GHz Wireless Radio Microcontrollers (MCUs) based on Arm® Cortex®-M0+ Core
Overview
Features
Features
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 KB)
- Supports point-to-point communication (bi-directional RF communication link), broadcast communication
