The new NXP connectivity MCUs allow Bluetooth LE devices to communicate at distances of more than a mile and increase the amount of Bluetooth advertising channels and advertising data within the Bluetooth standard, the predominant IoT protocol.
The KW39/38/37 wireless MCUs are designed with automotive and industry-grade hardware and software, along with robust serial communications with CAN-FD peripherals. The new devices are ideally suited for automotive applications, such as keyless entry, sensors and wireless onboard diagnostic functions. Additionally, they enable applications such as building control and monitoring, fire and safety, home and institutional healthcare, asset management and monitoring and a range of other use cases.
Delivering best-in-class RF performance, the KW39/38/37 family features extreme RX sensitivity to allow for the long range Bluetooth Low Energy connections. The new devices achieve -105 dBM RX sensitivity with LE-coded 125 kbits/s data rate, for example, allowing for connections in harsh environments and at extended distances. In addition, the radio conveniently supports up to 8 simultaneous secure connections in any master/slave combination, allowing multiple authorized users to communicate with the device. The MCU’s innovative data stream buffer allows the capture of radio parameters without stalling processor or DMA operations, enabling high-accuracy measurements needed for distance and angle approximations.
NXP’s MCUXpresso Tool Suite features a certified Bluetooth Low Energy software stack with application programming interface calls. The new KW39/38/37 MCUs extend the previous generation of devices with hardware and software compatibilities for faster design cycles. In addition, the KW38 MCU integrated FlexCAN, enables seamless integration into an industrial CAN communication network or an automobile’s in-vehicles network. The FlexCAN module can support CAN’s flexible data rate (CAN FD) for increased bandwidth and lower latency.
