NXP Adds Bluetooth To MCUs
NXP has added to its KW3x family of microcontrollers (MCUs).
KW39/38/37 MCUs incorporate Bluetooth 5.0 long-range capabilities and expanded Bluetooth advertising channels.
Compatibility with hardware, software and tools usedwith the previous generation of devices -, KW34/35/36 – is maintained.
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. The new wireless MCU solutions allow developers to address emerging use cases within automotive and industrial digitization.
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 suitable 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 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 MCUs’ 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 MCUs extend the previous generation of devices with hardware and software compatibilities for faster design cycles.
The KW38 MCU integrated FlexCAN, enables 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.

New features:
• Integrating the long-range capability with Bluetooth Low Energy version 5.0 and generic FSK radio, the KW39/38/37 wireless MCUs feature AEC-Q100 Grade 2 and industrial qualifications for exceptional durability and performance for safety-critical applications
• RF transmit power and receive sensitivity enhancements, including: (1) -105 dBm typical Bluetooth LE sensitivity in 125 kbit/s; (2) -98 dBm typical Bluetooth LE sensitivity in 1 Mbit/s; (3) -101 dBm typical generic FSK (at 250 kbit/s) sensitivity; and (4) +5 dBm maximum Transmit output power provide an advanced link budget that helps ensure long range of communication and a high immunity to interference
• AES-128 accelerator: True random number generator for fast encryption/decryption, utilizing hardware security algorithms for network commissioning and transmissions of supported protocols
• 7 x 7 mm “wettable” flanks 48HVQFN package with up to 512 kB flash memory with ECC and 64 kB SRAM, allowing plenty of space for protocol stacks, application profiles and custom user firmware
