NXP's Kinetis® KW41Z / 31Z / 21Z MCU family supports true multi-protocol single chip designs, capable of running two stacks concurrently. These MCUs incorporate a 2.4 GHz transceiver that enables the use of Bluetooth® low energy (BLE) v4.2 and IEEE® 802.15.4 (thread). Built on ARM® Cortex®-M0+ core, with up to 512 Kb of Flash and up to 128 Kb of SRAM, ultra low-power radio and standby currents, highly-integrated connectivity, security and analog capabilities, make these MCUs the ideal solution for connected portable, battery-powered applications.
There are three devices included in this KW41Z MCU family that all have the same features and specifications, but support different radio protocols as follows:

The Kinetis KW41Z family of MCUs is an excellent solution for designs that require concurrent communication on both a BLE link and an 802.15.4 based network such as thread. These multi-mode capabilities enable direct communication using BLE via a mobile device or tablet and communication in a mesh network for local and remote control / monitoring.
To complement the offering, NXP includes a comprehensive suite of enablement of software and tools to help designs reach market faster and more robustly.
