Product details
Overview
LTP5903IPC-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 WirelessHART (IEC 62591) protocol stack, supports up to 500-node networks, delivers >99.999% reliability in industrial RF environments, and provides Ethernet and dual UART interfaces for data ingress/egress.
For engineers reviewing the LTP5903IPC-WHRC4B1#PBF datasheet, LTP5903IPC-WHRC4B1#PBF pinout, LTP5903IPC-WHRC4B1#PBF application, or LTP5903IPC-WHRC4B1#PBF equivalent, key selection considerations include IEEE 802.15.4 radio compliance (2.4–2.4835 GHz), deterministic power management for battery-operated motes, NIST-certified security, and dual hardware interface support (10/100Base-T Ethernet + two UARTs).
Technical Context
The LTP5903IPC-WHRC4B1#PBF executes Dust Networks' SmartMesh WirelessHART software stack on an integrated processor, enabling time-synchronized, frequency-hopping mesh networking with spatially diverse redundant topologies. It performs dynamic network optimization using real-time link quality reports from motes to maintain >99.999% reliability under RF interference and physical obstructions.
Its hardware interfaces include a 10/100Base-T Ethernet port (RX_P/TX_P/RX_N/TX_N), two UARTs (Serial 1: 5-pin LVTTL @ 115.2 kbps; Serial 2: 9-pin LVTTL @ 115.2 kbps), SD card interface, and MMCX antenna connector. The board integrates a battery-backed RTC (5–7 yr typical life) and supports NTP synchronization for UTC time accuracy within ±1 min/month at 25°C.
