Product details
Overview
LTP5903CEN-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 routing, NIST-certified security, and dynamic network optimization to manage up to 250 nodes with >99.999% reliability in industrial RF environments.
For engineers reviewing the LTP5903CEN-WHRB4B1#PBF datasheet, LTP5903CEN-WHRB4B1#PBF pinout, LTP5903CEN-WHRB4B1#PBF application, or LTP5903CEN-WHRB4B1#PBF equivalent, this module serves as the certified, production-ready hardware platform for deploying WirelessHART (IEC 62591) networks-supporting Ethernet and dual UART interfaces, deterministic power management, and factory-validated SmartMesh networking software.
Technical Context
The LTP5903CEN-WHRB4B1#PBF executes Dust Networks' SmartMesh WirelessHART stack on an integrated processor, enabling time-synchronized TDMA scheduling, per-packet frequency hopping across 15 channels in 2.4–2.4835 GHz, 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/TX differential pairs), two LVTTL UARTs (Serial 1 at 115.2 kbps, Serial 2 with RTS/CTS), SD card interface, LED status indicators, and MMCX antenna connector. The board integrates a battery-backed RTC (5–7 yr typical backup life) and supports NTP synchronization for UTC time accuracy within ±1 min/month at 25°C.

FAQ
What is the maximum number of wireless sensor nodes supported by the LTP5903CEN-WHRB4B1#PBF?
The LTP5903CEN-WHRB4B1#PBF is the WHRB variant and supports up to 250 WirelessHART motes. This capacity is enforced by firmware licensing and memory allocation-distinct from the WHRC variant (500-node limit). Network scalability is maintained through time-synchronized TDMA scheduling and dynamic route optimization, ensuring consistent latency and reliability even at full capacity.
Does the LTP5903CEN-WHRB4B1#PBF include pre-installed WirelessHART networking software?
Yes, the LTP5903CEN-WHRB4B1#PBF ships with fully tested and validated SmartMesh WirelessHART network management software pre-loaded. This includes the complete stack-time synchronization, frequency hopping, security, routing, and network health monitoring-requiring no additional firmware development or stack porting by the customer.
What interfaces does the LTP5903CEN-WHRB4B1#PBF provide for host system integration?
The LTP5903CEN-WHRB4B1#PBF provides three primary hardware interfaces: 10/100Base-T Ethernet (via J10 pins RX_P/TX_P/RX_N/TX_N), Serial 1 (5-pin LVTTL UART at 115.2 kbps), and Serial 2 (9-pin LVTTL UART with RTS/CTS). All interfaces are accessible through standardized board-to-board connectors and supported by XML API, Admin Toolset Web UI, and CLI software layers.
Is the LTP5903CEN-WHRB4B1#PBF certified for global RF regulatory compliance?
Yes, the LTP5903CEN-WHRB4B1#PBF holds pre-approved RF certifications for FCC (USA), IC (Canada), CE (EU), and Japan Radio Law. These cover conducted emissions, radiated emissions, and antenna performance using approved MMCX-mounted +2 dBi omni-directional antennas-eliminating need for customer-level RF retesting.
What power supply requirements does the LTP5903CEN-WHRB4B1#PBF have?
The LTP5903CEN-WHRB4B1#PBF requires a +5V_IN supply between 4.0 V and 5.5 VDC, with typical average current draw of 150 mA at 5.0 V and 25°C. It also provides a regulated +3V3 output (3.13–3.47 V, up to 100 mA) for powering external circuitry-drawn from the same +5V_IN rail with proportional increase in input current.
