Product details
Overview
LTP5903CEN-WHRC4B1#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 to manage up to 500 nodes. It delivers >99.999% network reliability in industrial RF environments and supports Ethernet and dual UART interfaces for data ingress/egress.
For engineers reviewing the LTP5903CEN-WHRC4B1#PBF datasheet, LTP5903CEN-WHRC4B1#PBF pinout, LTP5903CEN-WHRC4B1#PBF application, or LTP5903CEN-WHRC4B1#PBF equivalent, key selection considerations include WirelessHART (IEC62591) compliance, dual UART interface timing (115.2 kbps, 8N1), Ethernet PHY integration requirements, +5V_IN supply range (4.0–5.5 V), and MMCX antenna interface with +2 dBi gain limit.
Technical Context
The LTP5903CEN-WHRC4B1#PBF executes Dust's validated SmartMesh WirelessHART software stack on an embedded processor, enabling time-synchronized scheduling, per-transmission frequency hopping across 15 channels in 2.400–2.4835 GHz band, and spatially diverse redundant topologies. Its NIST-certified security framework enforces end-to-end encryption and secure join procedures.
It integrates a battery-backed RTC (5–7 yr typical lifetime), dual LVTTL UARTs (Serial 1: 5-pin, Serial 2: 9-pin), 10/100Base-T Ethernet physical layer interface, SD card interface for datalogging, and LED status indicators-all accessible via two 40-pin FCI/Berg board-to-board connectors (J10 and J6).

Equivalent & Alternatives
The following parts are listed as comparable options for similar WirelessHART network management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Emerson 1420 Wireless Gateway | Pre-integrated enclosure, HART-IP/Ethernet/IP native support; no direct UART access to embedded stack | Deployed as turnkey field device; not intended for OEM board-level integration | Select when requiring UL/ATEX certification out-of-box and minimal firmware development effort |
| Honeywell ST9000 Wireless Gateway | Supports both WirelessHART and ISA100.11a; dual-band radio (2.4 GHz + 900 MHz); larger form factor | Used in hybrid networks where coexistence with legacy ISA100.11a infrastructure is required | Select when migrating mixed-protocol plants or needing sub-GHz fallback for long-range outdoor coverage |
Compared with LTP5903CEN-WHRC4B1#PBF, the Emerson 1420 offers faster deployment but less hardware design flexibility, while the Honeywell ST9000 adds protocol versatility at the cost of increased BOM complexity and footprint-making LTP5903CEN-WHRC4B1#PBF optimal for custom gateway designs prioritizing compactness, UART-level control, and deterministic power optimization.

FAQ
What is the maximum number of motes supported by the LTP5903CEN-WHRC4B1#PBF?
The LTP5903CEN-WHRC4B1#PBF supports up to 500 WirelessHART motes, as confirmed by the WHRC variant designation in its part number and documented in the SmartMesh WirelessHART User Guide. This capacity enables large-scale deployments such as refinery-wide instrumentation or multi-wellpad oilfield monitoring without requiring multiple gateways or complex network segmentation.
Does the LTP5903CEN-WHRC4B1#PBF include an integrated antenna or require an external one?
The LTP5903CEN-WHRC4B1#PBF does not include an integrated antenna; it provides an MMCX-compatible jack receptacle for external antenna connection. Per datasheet Section 5.2, the antenna must operate in 2.4–2.4835 GHz, exhibit ≤3:1 VSWR, and deliver ≤+2 dBi gain-requirements met by pre-approved models like Johanson 2450AT18A100E.
What power supply specifications are required for reliable operation of the LTP5903CEN-WHRC4B1#PBF?
The LTP5903CEN-WHRC4B1#PBF requires a regulated +5V_IN supply between 4.0 V and 5.5 V DC, with peak current capability of 350 mA and average current of 150–225 mA depending on +3V3 load. Voltage ripple must remain below 100 mVp-p from 50 Hz to 50 MHz, as specified in Table 2 of the datasheet, to prevent radio performance degradation or reset instability.
Can the LTP5903CEN-WHRC4B1#PBF be configured remotely via Ethernet, and what protocols are supported?
Yes, the LTP5903CEN-WHRC4B1#PBF supports full remote configuration over Ethernet via its XML API and web-based Admin Toolset. The XML API uses XML-RPC over HTTP/HTTPS for programmatic control, while the Admin Toolset provides a browser interface for IP settings, NTP synchronization, log review, and mote firmware updates-both accessible on the default 192.168.1.100 address.
Is the LTP5903CEN-WHRC4B1#PBF compliant with global RF regulations, and which certifications apply?
Yes, the LTP5903CEN-WHRC4B1#PBF holds FCC (USA), IC (Canada), CE (EU), and Japan Radio Law certifications for its 2.4 GHz radio module, as detailed in Section 10 of the datasheet. These approvals cover conducted emissions, radiated emissions, and antenna interface compliance-enabling global deployment without additional regional testing when using approved antennas and enclosure practices.
