Smart Way To Connect And Control Low-Powered IoT Devices


The newly launched microcontroller (MCU) from Freescale provides an unique platform that makes way for a comprehensive solution for Internet-of-Things (IoT) applications and connectivity in a single package. As claimed by the company, the new 32-bit Kinetis KW41Z MCU is industry’s first multi-mode radio with thread support capable of running 802.15.4 and Bluetooth Smart. The following MCU is suited for applications that include portable health care devices, wearable sports and fitness devices, AV remote controls, computer keyboards and mice, gaming controllers, access control security systems, smartenergy and home area networks.

According to the press release, “The KW41Z is an ultra low-power, highly-integrated single-chip device that enables Bluetooth Smart/Bluetooth Low Energy (BLE) v4.2 and IEEE 802.15.4-2011 RF connectivity for portable, extremely low-power embedded systems. The KW41Z MCU integrates a 2.4GHz transceiver supporting FSK/GFSK and O-QPSK modulations, an ARM Cortex-M0+ CPU, up to 512KB Flash and up to 128KB SRAM, 802.15.4 packet processor, hardware security and peripherals optimised to meet the requirements of the target applications.”

In reference to the technical specification sheet, the MCU is an ideal solution for true single chip designs that require concurrent communication on both a Bluetooth Low Energy network and an 802.15.4 based network such as Thread or ZigBee. This multi-mode capability enables direct communication using Bluetooth Low Energy via a mobile device and participating in a mesh network for local and remote control/monitoring.


“Freescale is recognised as a longtime industry leader in MCU innovation, and we now are building on this leadership by redefining the state-of-the-art for wireless MCU connectivity,” said Emmanuel Sambuis, Executive Director, MCU and Connectivity Products at Freescale.
