NXP NXP Microcontroller Kinetis W, 56-Pin LGA MKW21D256VHA5

Kinetis KW Series Wireless Microcontrollers. The Kinetis KW2xD series of BLE/IEEE802.15.4 enabled wireless microcontrollers are cost-effective, low-power SoCs. They integrate a 2.4GHz radio transceiver and an ARM Cortex-M4 core processor. The KW01Z series features a sub-1GHz transceiver and a Cortex-M0+ core processor. Key applications for the KW series microcontrollers include smart metering, networked building management, home automation, medical/healthcare monitoring, industrial monitoring/control, and local communications for the Internet of Things (IoT). .KW2xD Series 2.4GHz BLE/IEEE802.15.4 Compatible RF TransceiverIdeal for operation in ISM and MBAN bands50MHz ARM Cortex-M4 core processorRF output power: up to +8dBmReceiver sensitivity: -102dBm@250kbpsModulation: OQPSKOTAData rate: 250kbps via one of 16 selectable channelsSupports Clear Channel Assessment (CCA), Energy Detection (ED), Link Quality Indication (LQI)Built-in profiles: SmartEnergy1.x, Home Automation, Health Management, Network stack based on RF4CEZigBeeProSerial communication: USBOTG (MKW22 only)SPI, ^I2C KW01Z Series Sub-1GHz ISM Band RF Transceiver 48MHz ARM Cortex-M0+ Core Processor (128KB Flash Memory, 16KB RAM) RF Output Power: Max +17dBm Receiver Sensitivity: -120dBm@1.2kbps Modulation: FSK, GFSK, MSK, GMSK, OOKOTA Data Rate: Max 600kbps Packet Engine with CRC, AES-128 Encryption, 66 Byte FIFO Serial Communication: SPI, I ² C, UART Power: +1.8→+3.6Vdc
