Product details
Overview
LTP5903-WHR from Analog Devices (formerly Linear Technology/Dust Networks) is a SmartMesh® WirelessHART embedded network manager PCB assembly designed for line-powered gateways and controllers. It implements full WirelessHART (IEC 62591) protocol stack, supports up to 500 nodes (LTP5903-WHRC variant), delivers >99.999% network reliability in industrial RF environments, and provides Ethernet and dual UART interfaces for data ingress/egress in process automation systems.
For engineers reviewing the LTP5903-WHR datasheet, LTP5903-WHR pinout, LTP5903-WHR application, or LTP5903-WHR equivalent, this page details its role as a standards-compliant, time-synchronized mesh network coordinator with deterministic power management, NIST-certified security, and field-proven sub-50 µA routing node compatibility.
Technical Context
The LTP5903-WHR integrates an IEEE 802.15.4 DSSS radio (2.4–2.4835 GHz, 250 kbps raw rate, –92.5 dBm sensitivity), a Linux-based embedded processor, and Dust's SmartMesh WirelessHART networking software. It performs real-time dynamic network optimization using mote-reported link quality metrics and enforces time-synchronized, frequency-hopping TDMA scheduling across spatially diverse topologies.
Its hardware interfaces include 10/100Base-T Ethernet (RX/TX differential pairs, nACT/nLINK LEDs), two LVTTL UARTs (Serial 1 at 115.2 kbps, Serial 2 with RTS/CTS), SD card interface, and battery-backed RTC (5–7 yr typical lifetime). All I/O operates at 3.3 V LVTTL levels with defined VIH/VIL thresholds and ±5 µA leakage.

Pinout & Package
Package: PCB assembly with two 40-pin FCI/Berg 61083-042400LF board-to-board connectors (J10 and J6); no IC-style package - it is a functional module requiring mounting and interconnect.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| J10 Pin 3 (RX_P) | Ethernet Receive Positive | Differential input for 10/100Base-T; requires external magnetics and RJ-45 connector for PHY compliance. |
| J10 Pin 17 (S1_TX) | Serial 1 Transmit | LVTTL Type 1 output (VOH ≥ 2.6 V, IOL = 8 mA); used for embedded controller configuration via 115.2 kbps UART. |

Applications
| Process Automation Gateway | Industrial Asset Monitoring Hub |
|---|---|
|
Use Scenario: Integration into a DCS or PLC rack as primary WirelessHART gateway, aggregating temperature, pressure, and valve position data from 300+ field devices. IC Role / Device Role / Timing Role: Acts as network manager and time master - synchronizes all motes to UTC via NTP and distributes TDMA schedule slots. Use Value: Eliminates wired I/O modules and conduit runs; maintains >99.999% uptime even during EMI events near VFDs or welding equipment. |
Use Scenario: Mounted in explosion-proof enclosure at refinery perimeter to monitor tank level, corrosion sensors, and flare stack emissions. IC Role / Device Role / Timing Role: Serves as secure, certified ingress/egress point - terminates WirelessHART traffic and forwards encrypted data via Ethernet to cloud SCADA. Use Value: Meets IEC 62591 and ATEX/IECEx zone requirements; enables predictive maintenance without exposing legacy control systems to wireless traffic. |
| Smart Grid Substation Controller | Water/Wastewater SCADA Node |
|
Use Scenario: Deployed in outdoor substation cabinet to collect breaker status, transformer oil temp, and partial discharge readings from wireless sensors. IC Role / Device Role / Timing Role: Functions as hardened edge coordinator - manages mote sleep cycles, enforces AES-128 encryption per packet, and logs UTC-stamped events locally on SD card. Use Value: Operates reliably at –40 °C to +85 °C; SD interface enables offline datalogging during cellular backhaul outages. |
Use Scenario: Installed in municipal water pump station to coordinate pH, turbidity, flow, and chlorine residual sensors across multiple wells and tanks. IC Role / Device Role / Timing Role: Provides bidirectional command capability - sends setpoints to smart actuators and receives confirmation ACKs via deterministic routing.

FAQ
What is the maximum number of nodes supported by the LTP5903-WHR?
The LTP5903-WHR supports up to 500 nodes in the WHRC variant and up to 250 nodes in the WHRB variant. This capacity is achieved through optimized TDMA slot allocation and dynamic route discovery within the SmartMesh WirelessHART stack. The LTP5903-WHR itself does not impose software licensing limits - node count is constrained by radio channel utilization and memory footprint of the embedded Linux runtime. For deployments exceeding 500 nodes, multiple LTP5903-WHR units can be deployed in hierarchical network topologies.
Does the LTP5903-WHR require an external antenna, and what are the specifications?
Yes, the LTP5903-WHR requires an external 2.4–2.4835 GHz antenna connected via MMCX jack. Per specification, the antenna must have 50 Ω impedance, ≤ +2 dBi gain, omni-directional pattern, and ≤ 3:1 VSWR. Pre-approved antennas are listed in section 10.1.2 of the official datasheet. Mounting must allow vertical orientation and protrusion outside any metal enclosure to maintain free-space radiation performance - internal PCB antennas or chip antennas are not supported.
Can the LTP5903-WHR operate without Ethernet, using only UART interfaces?
Yes, the LTP5903-WHR fully supports headless operation via Serial 1 or Serial 2 UARTs. Serial 1 (5-pin, 115.2 kbps) provides full XML API access for configuration and data exchange; Serial 2 (9-pin, 115.2 kbps with RTS/CTS) supports CLI for diagnostics and troubleshooting. Ethernet is optional but required for Admin Toolset web interface and NTP synchronization. All core WirelessHART management functions remain active regardless of Ethernet presence.
What is the purpose of the +3V3 output pins on the LTP5903-WHR?
The +3V3 output pins (J10 Pins 11, 12, 25 and J6 Pins 20, 21) deliver a regulated 3.3 V ±5% supply capable of sourcing up to 100 mA total. This rail is intended to power external circuitry such as isolated RS-485 transceivers, analog signal conditioners, or optocouplers - eliminating need for separate DC-DC converters. Current drawn from +3V3 increases load on the main +5V_IN supply, so total system power budget must account for both rails.
How is factory reset performed on the LTP5903-WHR, and what settings are restored?
Factory reset is triggered by asserting the Restore Switch input (J10 Pin 20) within 20 seconds after releasing nRESET_IN (J6 Pin 28). This action restores IP address, PPP settings, serial port parameters, username/password, wireless network ID, join key, ACL, logs, OTAP files, and mote list - effectively returning the LTP5903-WHR to out-of-box state. The debounce circuit on the Restore Switch input allows direct connection to a momentary push button without external filtering.
