According to NXP, the KW39/38/37 MCUs add Bluetooth 5.0 long-range capabilities and expanded Bluetooth advertising channels. These enhancements come with a seamless migration with hardware, software and tools compatibility with the previous generation of devices, KW34/35/36.
The 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. These wireless MCU solutions also allow developers to address emerging use cases within automotive and industrial digitisation.
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. These devices are intended for automotive applications, such as keyless entry, sensors and wireless onboard diagnostic functions. Additionally, they enable industrial applications such as building control and monitoring, fire and safety, home and institutional healthcare, asset management and monitoring and a range of other industrial use cases.
The KW39/38/37 family features extreme RX sensitivity to allow for the long range Bluetooth Low Energy connections - achieving -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 data stream buffer allows the capture of radio parameters without stalling processor or DMA operations, enabling high-accuracy measurements.
NXP’s MCUXpresso Tool Suite features a certified Bluetooth Low Energy software stack with application programming interface calls. The 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 module can support CAN’s flexible data rate (CAN FD) for increased bandwidth and lower latency, and enables seamless integration into an industrial CAN communication network or an automobile’s in-vehicles network..
