Freescale's new Kinetis KW20 wireless MCUs expands on the successful Kinetis MCU family based on the ARM® Cortex™-M4 CPU core. The Kinetis KW20 Wireless MCU integrates a class-leading RF transceiver, Cortex™-M4 and a robust feature set for reliable, secure, and low-power IEEE® 802.15.4 wireless solutions.
These wireless MCUs offer up to 512 KB of flash, 64 KB of RAM and up to 64 KB of FlexMemory. Dual PAN support allows the system to simultaneously participate in two ZigBee® networks, eliminating the need for multiple radios. Software protocol stacks, tools, and IDE are compatible with Kinetis MCUs.
