Refer to section 7.1 for timing requirements on the RST reset using the mote serial command (see the SmartMesh IA-510 Mote Serial API Guide). ¯¯¯¯ input pin is optional, and must either be driven or pulled up with a 5.1 MΩ resistor. Unless noted otherwise, all The TIME signals are active low. LTP5900 Mote Datasheet Dust Networks 7 Figure 1 LTP5900 Package with Pin Labels 6.0 Power Supply Design Care should be taken in cases where the mote inputs will be driven to logic level high. Refer to the 040-0067 SmartMesh IA510 Mote Serial API Guide for information on mote bring-up and power cycling. 7.0 Mote Boot Up 7.1 Power-on Sequence The LTP5900 has internal power-on reset circuits that ensure that the mote will properly boot. External resetting of the device is not required and not recommended. Table 9 Power-on Sequence Parameter ¯¯¯ pulse width RST 7.2 Min Typ Max 125 Units µs Comments Reset timing Inrush Current During power on, the mote can be modeled as a lumped impedance, as shown in Figure 2. With a source impedance (Rsrc) of 1 Ω, the inrush current on the mote appears as shown in Figure 3. 8 Dust Networks LTP5900 Mote Datasheet Figure 2 LTP5900 Equivalent Series RC Circuit VDD Inrush Current (Power On with Supply Impedance of 1 Ohm) 2000 1750 Current (mA) 1500 1250 1000 750 500 250 0 0 10 20 30 40 50 Time (us) Figure 3 7.3 VDD Inrush Current Mote Boot Sequence Current ¯¯¯ the mote completes its boot-up process by loading the application image and loading the Following the negation of RST operating parameters. The LTP5900 lowers average current consumption by spreading the boot operation over time. This method supports systems with supplies having a maximum DC current less than the peak current required by the LTP5900. These systems must store enough charge to maintain the supply through the LTP5900’s peak current consumption. For more information, contact your Dust Networks applications engineer. The maximum “average current” consumption for the LTP5900 is defined by the maximum total charge Q consumed over a sliding window in time, Twindow.

The LTP5900 serial interface boots within tboot_delay Upon LTP5900 power up, the MT_CTS (see 7.3 Mote Boot Sequence) of the mote powering up, at which time the LTP5900 will transmit an HDLC boot event packet. Note that full handshake is in effect and is required to receive this packet. 8.0 Interfaces 8.1 Reset Pin The /RST input pin is internally pulled up. Connecting it is optional; however, in applications operating in the presence of EMI, /RST should be actively driven high. When driven low, the mote hardware is in reset. Note that the mote may also be reset using the mote reset command (0x08). For requirements on reset timing, see section 7.1. The LTP5900 is a highly sophisticated device and Dust Networks recommends doing resets gracefully. If the device is in the network, a disconnect command (0x07) should be issued before the /RST signal is asserted. This will result in the device rebooting and sending the “boot” event. The /RST signal may then be asserted since the device is not in the network. Refer to the SmartMesh IA-510 LTP5900 Integration Guide for recommendations on how to connect to the /RST pin, including voltage supervision. For detailed information about mote serial commands, refer to the SmartMesh IA-510 Mote Serial API Guide. 8.2 Timestamps The LTP5900 has the ability to deliver network-wide synchronized timestamps. The LTP5900 sends a time packet (as described in the SmartMesh IA-510 Mote Serial API Guide) through its serial interface when one of the following occurs: • Mote receives an HDLC request to read time • ¯¯¯¯ signal is asserted The TIME ¯¯¯¯ pin is optional and has the advantage of being more accurate. The value of the timestamp is taken within The TIME ¯¯¯¯ signal activation. If the HDLC request is used, due to packet processing the value of approximately 1 ms of receiving a TIME the timestamp may be captured several milliseconds after receipt of the packet. Refer to the IA-510 Mote Serial API Guide for more information on timestamps. 10 Dust Networks LTP5900 Mote Datasheet Figure 5 ¯¯¯¯ Pin Operation of TIME ¯¯¯¯ Timing Values Table 11 TIME Variable Description Min tstrobe ¯¯¯¯ strobe pulse width TIME tresponse Negation of Time strobe to start of time packet 8.3 Max 125 Units µs 100 ms Settable I/O Modes The LTP5900 offers a choice of two I/O modes. The functionality of the interface will be determined by the setting of Mode pin B whose pinout is described in 5.0 Pinout. Table 12 Mode Pin Settings Pin Mode pin B Mode 1 Mode 3 Externally tied low Externally tied high All modes provide a means of transmitting and receiving serial data through the wireless network, as well as a command interface that provides synchronized time stamping, local configuration, and diagnostics. Mode 1 implements an 8-bit, no parity, 9600 bps baud three, four or five-signal serial interface with bidirectional packetlevel flow control operating at 9600 bps. In certain OEM designs, one or two of the serial handshake signals may be optional for reduced pin count, as described in Table 13. Mode 3 implements an 8-bit, no parity, 115.2 kbps baud five-signal serial interface with bidirectional packet-level flow control and byte-level flow control in the mote-to-microprocessor direction only. 8.3.1 Mode 1: Three/Four/Five-signal Serial Interface (9600 bps) The LTP5900 mode 1 provides a three, four, or five-signal serial interface that is optimized for low-powered embedded applications (and in certain designs may provide a low pin count serial solution). The mode 1 serial interface is comprised of ¯¯¯¯¯¯¯ , MT_CTS ¯¯¯¯¯¯¯ , ¯¯¯¯¯¯¯ the data pins (TX, RX) as well as handshake pins (MT_RTS SP_CTS) used for bidirectional flow control. The ¯¯¯¯¯¯¯ MT_RTS signal is ideal for designs where the microprocessor requires extra time to prepare to receive a packet (for example, the OEM microprocessor sleeps periodically, but requires a wake-up signal prior to receiving a packet). Refer to Table 13 for information on each handshake pin, including details on which pins are optional. LTP5900 Mote Datasheet Dust Networks 11 Table 13 Mode 1 Pin Usage Pin RX I/O Usage Input Serial data moving from the microprocessor to the mote. TX Output Serial data moving from the mote to the microprocessor. ¯¯¯¯¯¯¯ MT_RTS Output ¯¯¯¯¯¯¯ provides a mechanism to wake up the microprocessor in order to receive a MT_RTS packet. This signal is asserted when the mote is ready to send a serial packet. The signal ¯¯¯¯¯¯¯ signal from the microprocessor is detected low by the mote stays low until the SP_CTS (indicating readiness to receive a packet) or the ¯¯¯¯¯¯¯ times out, it will detMT_RTS to SP_CTS timeout defined in Section 8.3.3 expires.

When the microprocessor is capable of receiving a packet it should assert ¯¯¯¯¯¯¯ signal. the SP_CTS ¯¯¯¯¯¯¯ may be externally tied low (reducing pin count) only if the microprocessor is SP_CTS always ready to receive a serial packet. ¯¯¯¯¯¯¯ MT_CTS Output ¯¯¯¯¯¯¯ provides packet-level flow control for packets transferred from the microprocessor MT_CTS to the mote that are destined for transfer over the network.

(For a list of local commands, see the SmartMesh IA-510 Mote Serial API Guide.) ¯¯¯¯ TIME 8.3.2 Input ¯¯¯¯ pin can be used for triggering a timestamp packet. Its usage is optional. The TIME Mode 3: Five-signal Serial Interface (115.2 kbps) The LTP5900 mode 3 provides a five-signal serial interface with byte-level flow control on transfers from the mote to the ¯¯¯¯¯¯¯ , microprocessor. The mode 3 serial interface is comprised of the data pins (TX, RX) as well as handshake pins (MT_RTS ¯¯¯¯¯¯¯ , ¯¯¯¯¯¯¯ ¯¯¯¯¯¯¯ signal is ideal for designs where the microprocessor MT_CTS SP_CTS) used for bidirectional flow control. The MT_RTS requires extra time to prepare to receive a packet (for example, the OEM microprocessor sleeps periodically, but requires a wake-up signal prior to receiving a packet. Refer to Table 14 for information on each handshake pin, including details on which pins are optional. Table 14 Mode 3 Pin Usage Pin I/O Usage RX Input Serial data moving from the microprocessor to the mote. TX Output Serial data moving from the mote to the microprocessor. MT_RTS ¯¯¯¯¯¯¯ Output MT_RTS ¯¯¯¯¯¯¯ provides a mechanism to wake up the microprocessor in order to receive a packet. This signal is asserted when the mote is ready to send a serial packet. The signal stays low until the SP_CTS ¯¯¯¯¯¯¯ signal from the microprocessor is detected low by the mote (indicating readiness to receive a packet) or the tMT_RTS to SP_CTS timeout defined in Section 8.3.3 expires. If MT_RTS ¯¯¯¯¯¯¯ times out, it will de-assert MT_RTS ¯¯¯¯¯¯¯, wait for tMT_RTS retry and then re-assert MT_RTS ¯¯¯¯¯¯¯ to attempt to send the serial packet again (see Figure 9). SP_CTS ¯¯¯¯¯¯¯ Input SP_CTS ¯¯¯¯¯¯¯ provides byte-level flow control for packets transferred from the mote to the microprocessor. When the microprocessor is capable of receiving a packet it should assert the SP_CTS ¯¯¯¯¯¯¯ signal. In mode 3 byte-level flow control is achieved by having the microprocessor negate and then reassert the SP_CTS ¯¯¯¯¯¯¯ signal following the receipt of each byte. The mote will begin transmission of the next byte after detecting the reassertion of 12 Dust Networks LTP5900 Mote Datasheet SP_CTS ¯¯¯¯¯¯¯. MT_CTS ¯¯¯¯¯¯¯ Output MT_CTS ¯¯¯¯¯¯¯ provides packet-level flow control for packets transferred from the microprocessor to the mote that are destined for transfer over the network. Upon reset, following boot the mote will negate MT_CTS ¯¯¯¯¯¯¯ until the mote establishes a wireless network connection. During operation, the mote will negate MT_CTS ¯¯¯¯¯¯¯ if the mote does not have sufficient buffering to accept another packet. MT_CTS ¯¯¯¯¯¯¯ will also remain high if the mote is not part of the network. The microprocessor must check that the MT_CTS ¯¯¯¯¯¯¯ pin is low before initiating each serial packet for wireless transmission. Note that the mote may receive local serial packets at any time regardless of the MT_CTS ¯¯¯¯¯¯¯ state. For a list of local commands, see the SmartMesh IA-510 Mote Serial API Guide.

A Declaration of Conformity must be issued for each of these standards and kept on file as described in Annex II of the R&TTE Directive. Furthermore, the manufacturer must maintain a copy of this LTP5900 user documentation and ensure the final product does not exceed the specified power ratings, antenna specifications, and/or installation requirements as specified in the user manual. If any of these specifications are exceeded in the final product, a submission must be made to a notified body for compliance testing to all required standards. 10.3.3 OEM Labeling Requirements The ‘CE’ marking must be affixed to a visible location on the OEM product. The CE mark shall consist of the initials “CE” taking the following form: If the CE marking is reduced or enlarged, the proportions given in the drawing below must be respected. The CE marking must have a height of at least 5 mm except where this is not possible on account of the nature of the apparatus. The CE marking must be affixed visibly, legibly, and indelibly. Furthermore, since the usage of the 2400 – 2483.5 MHz band is not harmonized throughout Europe, the Restriction sign must be placed to the right of the ‘CE’ marking as shown below. See the R&TTE Directive, Article 12 and Annex VII for more information. Figure 13 CE Label Requirements 10.3.4 Restrictions Norway prohibits operation near Ny-Alesund in Svalbard.
