KW39/38/37 wireless MCUs integrate long-range capability with Bluetooth Low Energy version 5.0 and generic FSK
radio. Achieving -105 dBm sensitivity with LE-coded 125 kbit/s data rate allows for connections in harsh
environments and at extended distances. The innovative data stream buffer allows the capture of radio parameters
without stalling processor or DMA operations. This capability enables high-accuracy measurements needed for distance
and angle approximations. The radio supports up to 8 simultaneous secure connections in any master/slave combination
allowing multiple authorized users to communicate with the device.
The KW38 MCU additionally integrates FlexCAN, helping enable seamless integration into an automobile’s in-vehicle or
industrial CAN communication network. The FlexCAN module can support CAN’s flexible data rate (CAN FD) for increased
bandwidth and lower latency.
