The Kinetis KW40Z/30Z/20Z (KW40Z) wireless MCU family is the first multi-mode radio in
the Kinetis portfolio. Integrating a Bluetooth® Low Energy (BLE) v4.1 and IEEE® 802.15.4-
2011 compliant modem, it can support both standards and run in concurrent mode.

The KW40Z MCU integrates a buck-boost DC/DC converter,
supporting a wide range of operating voltages from 0.9 V to 4.2
V, which significantly reduces the peak current in receive mode
down to 6.5 mA and transmit down to 8.4 mA. At the same time
it delivers excellent link budget that ensures the longest range
of communication and high immunity to interference.
The KW40Z MCU offers Dual PAN support which allows the
system to concurrently participate in two 802.15.4 networks,
such as Thread® and ZigBee® or an 802.15.4 based network
and BLE, eliminating the need for multiple radios, reducing
system complexity and ultimately cost.
Take advantage of the robust enablement package that
includes the BLE Host Stack, Thread, ZigBee, 802.15.4 MAC
and Simple MAC (SMAC) software protocol stacks, RTOS,
development tools and IDE that are designed for use with
Kinetis KW40Z MCUs and fully integrated in the Kinetis
Software Development Kit (KSDK).
