KW39/38/37 wireless MCUs integrate long-range capability with Bluetooth Low Energy version 5.0 and generic FSKradio. Achieving -105 dBm sensitivity with LE-coded 125 kbit/s data rate allows for connections in harshenvironments and at extended distances. The innovative data stream buffer allows the capture of radio parameterswithout stalling processor or DMA operations. This capability enables high-accuracy measurements needed for distanceand angle approximations. The radio supports up to 8 simultaneous secure connections in any master/slave combinationallowing multiple authorized users to communicate with the device.The KW38 MCU additionally integrates FlexCAN, helping enable seamless integration into an automobile’s in-vehicle orindustrial CAN communication network. The FlexCAN module can support CAN’s flexible data rate (CAN FD) for increasedbandwidth and lower latency.\n
