Freescale Kinetis KW0x无线MCU开发方案
Freescale公司的Kinetis KW0x系列产品是低于1GHz的无线MCU,集成了支持FSK, GFSK, MSK或OOK调制的收发器和低功耗ARM® Cortex M0+ CPU.集成的收发器工作频率包括ISM频段的315 MHz, 433 MHz, 470 MHz, 868 MHz, 915 MHz, 928 MHz和955 MHz,主要用在自动读表,无线传感器网络,家庭和建筑物自动化,工业监控以及无线告警和安全系统.本文介绍了KW0x系列主要特性,框图和应用电路, MKW01收发器框图以及参考板MRB-KW0x和TWR-RF Module主要特性,电路图,多个频段的材料清单和PCB元件布局图.
The MKW01 device is highly-integrated, cost-effective, smart radio, sub-1 GHz wireless node solution composed of a transceiver supporting FSK, GFSK, MSK, or OOK modulations with a low-power ARM® Cortex M0+ CPU. The highly integrated RF transceiver operates over a wide frequency range including 315 MHz, 433 MHz, 470 MHz, 868 MHz, 915 MHz, 928 MHz, and 955 MHz in the license-free Industrial, Scientific and Medical (ISM) frequency bands. This configuration allows users to minimize the use of external components.
The MKW01 is targeted for the following low-power wireless applications:
• Automated Meter Reading
• Wireless Sensor Networks
• Home and Building Automation
• Wireless Alarm and Security Systems
• Industrial Monitoring and Control..
