LTP5902IPC-WHMA#PBF 概述
A wireless mote module is a self-contained sub-system that combines a radio transceiver, microcontroller, and qualified protocol stack on a single PCB so that designers can add mesh networking to a sensor node without writing low-level radio firmware. Within the broader SmartMesh hierarchy, the LTP5902 sits inside Dust Networks' WirelessHART / 6LoWPAN product tree, which itself belongs to the 802.15.4 family of low-rate wireless personal area network (LR-WPAN) standards. SmartMesh WirelessHART networks are self-managing, ultra-low-power mesh networks optimized for industrial process automation.
Key features of the LTP5902IPC-WHMA#PBF include transmit current of 5.4 mA to 9.7 mA depending on output power, receive current of 4.5 mA, an integrated ARM Cortex-M3 microprocessor for on-module application processing, and a hardware SPI host interface that exposes network and application services to an external microcontroller. Each mote functions as a full routing node, providing redundant self-healing mesh paths with ultra-low power consumption that enables multi-year battery life on a single cell.
The module combines a precision radio with built-in time-synchronized channel hopping, AES-128 encryption, and self-forming/self-healing mesh capabilities that meet the WirelessHART (IEC 62591) standard. This architecture lets industrial operators deploy dense, deterministic sensor networks without manual RF tuning, and it lets battery-powered field instruments operate reliably for years in harsh plant environments.
Typical applications include wireless process instrumentation, factory automation sensor networks, condition monitoring of rotating equipment, and battery-powered environmental sensors in oil and gas, pharmaceutical, and chemical plants. The Eterna family's ultra-low power consumption makes it suitable for intrinsically safe installations.
When designing with this module, observe the host MCU's SPI timing requirements, provide a clean regulated 3.3 V source with adequate decoupling, and select an MMCX antenna whose VSWR matches the 2.4 GHz band. Verify regulatory certifications for your target region (FCC, IC, ETSI) and follow Dust Networks SmartMesh XT/XD antenna placement guidelines to maximize mesh link margin.

LTP5902IPC-WHMA#PBF 的功率输入和热参数（由制造商发布）。
典型应用
LTP5902IPC-WHMA#PBF 适用于 6 应用s: Wireless Process Instrumentation, Factory Automation Sensor Networks, Condition Monitoring of Rotating Equipment, Oil and Gas Field Sensors, Battery-Powered Environmental Monitoring, Pharmaceutical and Food Process Plants.
Wireless Process Instrumentation
The LTP5902IPC-WHMA#PBF integrates an 8 dBm 802.15.4 radio, ARM Cortex-M3 application processor, and WirelessHART mesh stack on a single 66-lead PCB module, eliminating the need to write radio firmware for field instruments. Its 5.4 to 9.7 mA transmit current and 4.5 mA receive current enable multi-year battery life on a single lithium primary cell, while the SmartMesh WirelessHART mesh provides self-healing, time-synchronized, AES-128-encrypted routes that IEC 62591-compliant plant gateways can accept directly. Drop the module onto a custom sensor board, expose process variables over SPI, and the instrument becomes a WirelessHART field device ready to join the existing plant network.
推荐
Factory Automation Sensor Networks
SmartMesh WirelessHART mesh networks self-form and self-heal, so dense vibration, temperature, and proximity sensors across a manufacturing cell can come online without manual RF commissioning - an ideal match for the LTP5902IPC-WHMA#PBF's embedded mesh stack. With 8 dBm TX power in the 2.4 GHz ISM band, each mote covers a typical 50 to 100 m industrial cell, and the time-synchronized channel hopping guarantees deterministic latency that supervisory control loops can rely on. The MMCX antenna connector lets OEMs tune the antenna for metal-rich cabinet environments, while the -40 C to +85 C operating range supports unheated shop-floor panels.
推荐
Condition Monitoring of Rotating Equipment
Wireless vibration monitoring on pumps, motors, and compressors benefits from the LTP5902IPC-WHMA#PBF's ultra-low duty-cycle profile: the radio is in deep sleep most of the time, then wakes briefly to transmit a sampled waveform via the 250 kbps 802.15.4 link. AES-128 encryption protects proprietary vibration signatures, and the mesh self-heals when a motor is overhauled and a mote is temporarily removed. The MMCX antenna allows the integrator to mount the antenna outside a metal motor terminal box for reliable 2.4 GHz propagation, while SPI exposes buffered accelerometer data to the host MCU at low power.
推荐
Oil and Gas Field Sensors
Upstream wellhead and downstream pipeline monitoring rely on long-life battery-powered WirelessHART devices, which is exactly the design point of the LTP5902IPC-WHMA#PBF. The module's AES-128 encryption and IEC 62591 WirelessHART compliance let it join existing Emerson/ABB/Yokogawa WirelessHART gateways without protocol translation, and its industrial -40 C to +85 C range survives Arctic, desert, and offshore cabinet environments. Host MCUs can offload the entire mesh networking stack to the on-board ARM Cortex-M3 and use SPI to read wellhead pressure, flow, and tank-level transducers, slashing OEM firmware development cost.
推荐
Battery-Powered Environmental Monitoring
Environmental sensors in chemical plants, pharmaceutical sites, and power stations need to run for years on a primary cell, which the LTP5902IPC-WHMA#PBF's 5.4 to 9.7 mA TX and 4.5 mA RX profile enables. WirelessHART mesh networking means a sensor can route through neighboring motes to reach the gateway even when line-of-sight is blocked by tanks or buildings, and time-synchronized channel hopping avoids the 2.4 GHz Wi-Fi congestion typical of office-adjacent plants. The MMCX antenna connector permits an external high-gain antenna for obstructed deployments.
推荐
Pharmaceutical and Food Process Plants
Clean-in-place (CIP) skids, lyophilizers, and batch reactors in pharma/food plants demand hygienic wireless sensors with reliable, deterministic mesh networking - the LTP5902IPC-WHMA#PBF provides WirelessHART IEC 62591 compliance out of the box. Its MMCX antenna can be sealed behind a stainless-steel enclosure using a feedthrough, and the -40 C to +85 C industrial temperature range supports steam-cleaned and cold-room environments. The on-board ARM Cortex-M3 runs application code that reads temperature, conductivity, and pH sensors over SPI, while mesh routing to the plant's existing WirelessHART gateway removes the need for new infrastructure.

设计说明
Provide a clean regulated 3.3 V supply with at least 10 uF of bulk decoupling plus a 0.1 uF ceramic capacitor placed within 5 mm of the module's VCC pad. The LTP5902IPC-WHMA#PBF draws 5.4 to 9.7 mA in transmit and 4.5 mA in receive; an LDO with sub-30 uVrms noise is recommended to keep the radio's phase noise within WirelessHART spec. For battery-powered nodes, size the primary cell to support the average current draw plus peak transmit bursts - Dust Networks SmartMesh Power Calculator is the reference tool.
Mount the MMCX antenna connector at the edge of the host PCB with a continuous ground plane beneath the module and a clear keep-out zone (no copper, no traces, no components) extending at least 5 mm around the antenna feed. Route SPI traces as short, matched-length pairs with a contiguous ground reference and place series resistors near the host MCU. Follow the SmartMesh WirelessHART Mote Hardware Integration Guide antenna placement rules to preserve the rated link budget and regulatory emissions compliance (FCC, IC, ETSI).
Do not substitute a 2.4 GHz Wi-Fi antenna without verifying VSWR across 2.4000 to 2.4835 GHz - high VSWR collapses the link budget and can cause intermittent joins. Confirm the host MCU's SPI peripheral can support the SmartMesh API clock rate and mode used by the LTP5902IPC-WHMA#PBF; mismatched CPOL/CPHA settings will hang the network join. Verify that the WirelessHART network manager on your gateway accepts the firmware revision printed on the module label before deploying a fleet.
