NXP Semiconductors KW39/38/37 MCUs

The KW39/38/37 are based on Arm® Cortex®-M0+ at 48 MHz with up to 512 KB on-chip flash with error code correction (ECC), 64 KB SRAM and highly-integrated connectivity, security and analog capabilities. These 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 KW38 MCU integrates FlexCAN, enabling integration into an automotive or industrial CAN network, supporting CAN flexible data rate (CAN FD).
