Product details
Overview
LTP5903IPC-WHRB4B1#PBF 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 IEEE 802.15.4-compliant radio transceiver, time-synchronized mesh networking stack, and deterministic power management - enabling self-healing networks of up to 250 nodes with >99.999% reliability in industrial RF environments. It serves as the central data ingress/egress point via Ethernet and dual UART interfaces.
For engineers reviewing the LTP5903IPC-WHRB4B1#PBF datasheet, LTP5903IPC-WHRB4B1#PBF pinout, LTP5903IPC-WHRB4B1#PBF application, or LTP5903IPC-WHRB4B1#PBF equivalent, this page provides verified hardware interface definitions, real-time clock behavior, radio performance metrics, regulatory certifications (FCC/IC/CE/Japan Radio Law), and integration guidance for industrial wireless sensor network gateways.
Technical Context
The LTP5903IPC-WHRB4B1#PBF executes Dust Networks' SmartMesh WirelessHART software stack on an integrated embedded processor, enforcing IEC62591 compliance through time-synchronized TDMA scheduling, per-packet frequency hopping across 15 channels in 2.4–2.4835 GHz band, and spatially diverse redundant topologies. Its deterministic power management dynamically reroutes traffic to extend mote battery life beyond 10 years.
Hardware interfaces include 10/100Base-T Ethernet (RX_P/TX_P/RX_N/TX_N), two LVTTL UARTs (Serial 1: 115.2 kbps, 5-pin; Serial 2: 115.2 kbps, 9-pin with RTS/CTS), SD card interface, LED status indicators, and restore/reset control logic with debounced input. All digital I/O conforms to LVTTL voltage levels with defined VIH/VIL/VOH/VOL thresholds and ±5 µA leakage.

FAQ
What is the maximum number of motes supported by the LTP5903IPC-WHRB4B1#PBF?
The LTP5903IPC-WHRB4B1#PBF is the LTP5903-WHRB variant and supports networks of up to 250 WirelessHART motes. This capacity is fixed by firmware and memory allocation; it does not scale to the 500-mote capability of the WHRC variant. Network scalability is maintained through intelligent routing and dynamic topology optimization without requiring gateway hardware upgrades.
Does the LTP5903IPC-WHRB4B1#PBF include an integrated antenna or require an external one?
The LTP5903IPC-WHRB4B1#PBF does not include an integrated antenna. It features an MMCX-compatible jack receptacle for connection to an external 2.4–2.4835 GHz antenna with 50 Ω impedance and ≤+2 dBi gain. Pre-approved antennas are listed in Section 10.1.2 of the datasheet, and optimal placement requires vertical orientation with radiating element outside any enclosure.
What interfaces does the LTP5903IPC-WHRB4B1#PBF provide for host processor communication?
The LTP5903IPC-WHRB4B1#PBF provides three primary host interfaces: 10/100Base-T Ethernet (via J10 pins RX_P/TX_P/RX_N/TX_N), Serial 1 UART (5-pin LVTTL at 115.2 kbps, J10 pins S1_TX/S1_RX), and Serial 2 UART (9-pin LVTTL with RTS/CTS, J6 pins S2_TX/S2_RX/S2_RTS/S2_CTS). All digital I/O adheres to defined LVTTL voltage thresholds and timing specifications.
How is factory reset performed on the LTP5903IPC-WHRB4B1#PBF?
Factory reset on the LTP5903IPC-WHRB4B1#PBF is triggered by asserting the Restore Switch input (J10 Pin 20) low within 3 seconds after releasing nRESET_IN (J6 Pin 28). The internal debounce circuit allows direct connection to a mechanical push button. This action restores IP settings, serial port configuration, wireless network ID, join key, ACL, logs, and mote list to Dust factory defaults - erasing all custom configurations.
Is the LTP5903IPC-WHRB4B1#PBF RoHS compliant and what certifications does it hold?
Yes, the LTP5903IPC-WHRB4B1#PBF is RoHS compliant (per Section 10.5) and carries full regulatory certifications: FCC Part 15 (USA), IC RSS-247 (Canada), CE RED Directive (EU), and Japan Radio Law (Article 2, Section 2). These certifications cover conducted/radiated emissions, immunity, and antenna interface compliance - enabling global deployment without retesting.
