M2135-1/M2030-1 MOTE DATASHEETDUST NETWORKS™ CONFIDENTIAL Product Description The SmartMesh-XT™ M2135-1 and M2030-1 combine an industry-standard 802.15.4 radio with Time Synchronized Mesh Protocol (TSMP) to enable low-power wireless sensors and actuators with highly reliable wireless mesh networking. The M2135-1 and M2030-1 are tailored for use in battery- and line-powered wireless devices for applications that demand proven performance, scalability, and reliability. The M2135-1 and M2030-1 use the IEEE standard 802.15.4 radio, which operates in the global license-free 2.4 GHz band. The M2030-1 offers a range of up to 200 meters outdoors, while keeping power consumption as low as 50 μA. Ideal for longer range applications, the M2135-1 has a highly efficient power amplifier which allows communications to reach more than 400 meters outdoors, while advanced power management techniques keep power consumption down to as low as 55 μA in a typical network deployment. The combination of extremely high reliability and low power consumption enables applications that require very low installation cost and low-maintenance, long-term deployments. The standard serial interface of the M2135-1 and M2030-1 gives it flexibility to be used in a wide variety of different applications, from industrial process control to security, to lighting. When integrated into a product, the M2135-1 or M2030-1 acts like a network interface card (NIC)—it takes a data packet and makes sure that it successfully traverses the network. By isolating the wireless mesh networking protocols from the user, the M2135-1 and M2030-1 simplify the development process and reduce development risk. Key Features Reliable Networking •Uses Time Synchronized Mesh Protocol (TSMP) for high reliability (>99.9% typical network reliability) •Channel hopping over DSSS for interference rejection •Mesh networking for built-in redundancy •Every M2135-1/M2030-1 acts as both an endpoint and a router, increasing network reliability: “mesh-to-the-edge” •Automatic self-organizing mesh is built in Predictable Integration •Standard HDLC serial interface with bidirectional flow control •Industrial temperature range –40 to +85 °C •Supports socket or solder assembly •Rugged design for class I div I environments •FCC and IC modular certification (pending) •Certifiable for use in most countries worldwide (North America, Europe, and most Asian countries) Low Power Consumption •Ultra low-power components for long battery life •Network-wide coordination for efficient power usage •Down to 55 μA typical power consumption (M2135-1) Down to 50 μA typical power consumption (M2030-1) 802.15.4 Standard Radio •Global 2.4 GHz license-free band: suitable for use in North America, Europe, and most of Asia •31.6 mW (+15 dBm) EIRP RF output power (M2135-1) 0.6 mW (–2 dBM) EIRP RF output power (M2130-1) •–90 dBm receiver sensitivity •Outdoor range > 400 m typical (M2135-1) Outdoor range 200 m typical (M2030-1) •Direct-sequence spread spectrum (DSSS) for additional interference rejection M2135-1, M2030-1 2.4 GHz Wireless Serial Motes PRELMINARY 2DUST NETWORKS™M2135-1/M2030-1 MOTE DATASHEET Contents 1.0Absolute Maximum Ratings .................................................................................... 3 2.0Normal Operating Conditions ................................................................................. 3 3.0Electrical Specifications.......................................................................................... 4 3.1 Application Circuit.............................................................................................5 4.0Radio ...................................................................................................................... 5 4.1 Detailed Radio Specifications...............................................................................5 4.2 Antenna Specifications.......................................................................................6 5.0Pinout..................................................................................................................... 7 6.0Mote Boot Up.......................................................................................................... 8 6.1 Power-on Sequence...........................................................................................8 6.2 Inrush Current..................................................................................................8 6.3 Serial Interface Boot Up.....................................................................................9 7.0Interfaces............................................................................................................... 9 7.1 Timestamps......................................................................................................9 7.2 Status.............................................................................................................9 7.3 Serial Interface...............................................................................................10 7.3.1 Serial Handshake Protocol ...................................................................... 10 7.3.1.1 Serial Port................................................................................ 10 7.3.1.2 Serial Interface Boot Up............................................................. 11 7.3.1.3 Serial Interface Timing Requirements .......................................... 11 7.3.2 Mote Command Data Types .................................................................... 13 7.3.3 Mote Commands ................................................................................... 13 7.3.3.1 Command 0x80 Serial Payload Sent to Mote Serial ........................ 14 7.3.3.2 Command 0x81 Unacknowledged Serial Payload Received from Mote Serial .......................................................... 14 7.3.3.3 Command 0x82 Acknowledged Serial Payload Received from Mote Serial ......................…

M2030 Duty Cycle Description Dust radios operate on a TDMA time schedule that uses 31.25 ms timeslots. A transmit timeslot consists of 5 stages: 1. Initialization: radio is prepared for transmit (transmitter is off) 2. Ramp: transmitter is ramped to peak power 3. Transmit: 128 bytes of data maximum + 5 bytes preamble/SFD 4. Turnaround: radio is set to receive 5. Receive: radio waits in receive for ACK, then turns off Total transmit time for a 128 byte packet plus all overhead (SFD / Preamble / Ramp) is 4.34ms, shown in the figure below: CLRWR A IFB 10 MHz SGL AQT 10 msRef 5 dBmAtt 40 dB Center 2.405 GHz1 ms/ 1 AP PRN -45 -40 -35 -30 -25 -20 -15 -10 -5 0 5 1 Marker 1 [T1 ] -39.23 dB m 1.500000 ms 2 Delta 2 [T1 ] -0.31 dB 4.340000 ms Date: 28.NOV.2006 11:30:46 Maximum duty cycle is therefore: 4.34 ms on / (31.25 ms off) = 13.9 %
