KW39/38/37 Series MCUs

NXP's MCUs feature Bluetooth® long-range technology for superior durability and performance in safety-critical applications

Image of NXP's KW39/38/37 Series MCUsNXP's KW39/38/37 series of wireless MCUs integrate long-range capability with Bluetooth® Low Energy version 5.0 and generic FSK radio. Its ability to achieve -105 dBm sensitivity with an 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, such as phase without stalling processor or DMA operations. This capability enables high-accuracy measurements needed for distance and angle approximations. The radio supports up to eight simultaneous secure connections in any master and slave combination, allowing multiple authorized users to communicate with the device.

The KW39/38/37 series MCUs are based on the Arm® Cortex®-M0+ processor, run at 48 MHz, and feature up to 512 KB on-chip Flash with error code correction (ECC) and 64 KB SRAM with highly-integrated connectivity, security, and analog capabilities. The KW38 MCU additionally integrates FlexCAN, helping to 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.
