NXP MKW21D256VHA5 ARM Cortex M4 Microcontroller, 50 MHz, 256kB FLASH, 56-Pin LGA

The Kinetis KW2xD Series of BLE/IEEE 802.15.4 compliant wireless microcontrollers are cost-effective, low power SoCs incorporating a 2.4GHz radio transceiver and an ARM Cortex-M4 core processor. The KW01Z Series feature a Sub-1GHz transceiver and a Cortex-M0+ core processor. Applications for the KW Series microcontrollers include Smart Meters, networked building control, home automation, healthcare/medical monitoring, industrial monitoring/control and local communication for the Internet of Things (IoT).

The Kinetis range of ARM Cortex core microcontrollers consists of multiple hardware- and software-compatible Cortex-M0+ and Cortex-M4 MCU families with exceptional low-power performance, memory scalability and feature integration. Families range from the entry-level Cortex-M0+ Kinetis L Series to the high-performance, feature-rich Cortex-M4 Kinetis K and include a wide selection of analogue, communication, HMI, connectivity and security features.
