Kinetis^®KW41Z/31Z/21Z

MCUs for Wireless Applications

The Kinetis KW41Z/31Z/21Z MCU family for wireless applications is the second

multi-mode family in the Kinetis W series portfolio. Primarily used for automation and

healthcare purposes, these MCUs enable low-energy and long-range connectivity.

TARGET APPLICATIONS

} Home automation

} Healthcare

– Fitness monitoring

– Home healthcare

– Institutional care

OVERVIEW

Integrating a Bluetooth^®low energy (BLE) v4.2, Generic FSK

(at 250, 500 and 1000 kbit/s) and IEEE^®802.15.4 compliant

modem, Kinetis KW41Z/31Z/21Z MCUs can support multiple

protocols running concurrently (time slice) in a single chip.

These MCUs also integrate a buck-boost DC-DC converter,

supporting a wide range of operating voltages from 0.9 V

to 4.2 V, significantly reducing the peak current in receive

and transmit modes. At the same time, this MCU family

delivers an excellent link budget that ensures the longest

range of communication and high immunity to interference.

} Building automation

– Building control and monitoring

– Building HVAC control

– Fire/security

– Retail pricing management

– Security and access control

– Usage data collection

KW41Z/31Z/21Z MCUs offer multi-

protocol support which allow the

KINETIS KW41Z/31Z/21Z WIRELESS MCU FAMILY BLOCK DIAGRAM

system to concurrently operate in an

802.15.4 based network, like Thread,

and a BLE network, eliminating the need

for multiple radios, reducing system

complexity and cost. With up to 512 KB

of flash and up to 128 KB of SRAM on

chip, KW41Z/31Z/21Z MCUs provide

the ultimate option for running all your

connectivity needs in a single device.
