KW47 family features a 96 MHz Arm® Cortex®-M33 core coupled with a Bluetooth LE subsystem. The independent radio subsystem, with a dedicated core and memory, offloads the main CPU, preserving it for the primary application and allowing firmware updates to support future wireless standards. The KW47 also offers advanced security with an integrated EdgeLock® Secure Enclave Core Profile and will be supported by NXP's EdgeLock 2GO cloud services for credential sharing.
The KW47 family includes Bluetooth Channel Sounding capabilities, with a dedicated on-chip Localization Compute Engine to reduce ranging latency. It incorporates additional memory to support application-specific code, connectivity stacks and over-the-air firmware updates. This delivers reliable wireless performance, as the real-time activities of the radio run on a separate core from the application.
Building on NXP's strong history of providing automotive solutions, the KW47 family offers a wide operating temperature range from -40 °C to 125 °C and peripherals for automotive applications, KW47 will be part of NXP's 15-year Product Longevity program to support long-term use.
The KW47 series is supported by the MCUXpresso Developer Experience to optimize, ease and help accelerate embedded system development.
The KW47 is in pre-production, developers can get started today with the KW45, which is pin and software compatible.
