Design with multi-mode

(BLE/Generic- FSK/802.15.4) radio solutions

Kinetis ® KW41Z/31Z/21Z MCUs for Wireless Applications Kinetis ® KW41Z/31Z/21Z MCUs for Wireless Applications Design with multi-mode (BLE/Generic-FSK/802.15.4) radio solutions

Coming Soon Technical Seminar

The Kinetis KW41Z/31Z/21Z MCU family can support multiple protocols running concurrently (time slice) like Thread, based on 802.15.4 network, and a BLE network. Also integrate a buck-boost DC-DC converter, supporting a wide range of operating voltages from 0.9 V to 4.2 V.
