MKW41Z512VHT4
Overview
The MKW41Z512VHT4 is an ultra-low-power wireless microcontroller from NXP's Kinetis W series, featuring an ARM Cortex-M0+ core running at up to 48MHz. It integrates a 2.4GHz multi-protocol radio capable of simultaneous Bluetooth Low Energy v4.2 and IEEE 802.15.4 operation, supported by 512kB of Flash and 128kB of SRAM. The device is designed for battery-operated IoT applications, offering high sensitivity of -100dBm and an integrated on-chip balun to minimize external component count.
Why Choose This Part
This SoC excels by supporting concurrent multi-protocol operation, allowing a device to join a Thread mesh network while being commissioned via Bluetooth LE. Its high integration level, including an on-chip balun and bidirectional RF port, significantly reduces PCB area and BOM costs. Power efficiency is a primary benefit, featuring multiple very-low-leakage stop modes and a buck converter option that reduces run current to 4.8mA at 48MHz.
Applications
Key Specifications
Getting Started
Engineers should use the FRDM-KW41Z development board for rapid prototyping and evaluation. Software development is supported through the MCUXpresso SDK, which provides wireless stacks for BLE, Thread, and Zigbee. The toolchain integrates with MCUXpresso IDE, IAR Embedded Workbench, or Keil MDK for debugging and code optimization.
