Linear公司的LTC 5800-WHM系统级芯片(SoC)是IEEE 802.15.4 SoC解决方案的Eterna系列产品,片上集成了功率放大器(PA)和收发器和运行SmartMesh WirelessHART网络软件的ARM Cortex-M3微处理器,仅需要电源去耦电容,晶振和天线就可构成完整的无线网络节点,工业应用时的网络可靠性大于99.999% ,节点电流小于50uA,和WirelessHART (IEC62591)标准兼容.本文介绍了无线传感器网络特性, LTC5800-WHM SoC主要特性和Eterna框图,应用框图,以及SmartMesh WirelessHART入门套件主要特性, DC9003A-C SmartMesh WirelessHART评估/开发板电路图,材料清单和PCB元件布局图.

SmartMesh WirelessHART wireless sensor networks are self managing, low power networks built from wireless nodes called motes. The LTC®5800-WHM is the WirelessHART Mote-on-Chip™ integrated circuit in the Eterna®* family of IEEE 802.15.4 System-on-Chip (SoC) solutions, featuring a highly integrated, low power radio design by Dust Networks® as well as an ARM Cortex-M3 32-bit microprocessor running Dust’s embedded SmartMesh WirelessHART networking software.

The LTC5800-WHM SoC features an on-chip power amplifier (PA) and transceiver, requiring only power supply decoupling, crystals, and antenna with matching circuitry to create a complete wireless node.
