Product details
Overview
LTP5903CEN-WHRC4B3#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 form self-healing industrial wireless sensor networks supporting up to 500 nodes. It delivers >99.999% network reliability in dynamic RF environments and integrates Ethernet and dual UART interfaces for data ingress/egress.
For engineers reviewing the LTP5903CEN-WHRC4B3#PBF datasheet, LTP5903CEN-WHRC4B3#PBF pinout, LTP5903CEN-WHRC4B3#PBF application, or LTP5903CEN-WHRC4B3#PBF equivalent, this page provides verified technical context, interface specifications, real-time clock behavior, radio performance metrics, and integration-ready hardware/software interface details aligned with IEC62591 compliance requirements.
Technical Context
The LTP5903CEN-WHRC4B3#PBF executes Dust Networks' SmartMesh WirelessHART software stack on an embedded processor, enabling time-synchronized scheduling, per-transmission frequency hopping across 15 channels in the 2.4–2.4835 GHz ISM band, and spatially diverse redundant topologies. Its deterministic power management dynamically balances 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 at 115200 bps, Serial 2 with RTS/CTS), SD card support, LED status indicators, and a battery-backed RTC with ±1 min/month accuracy at 25°C. The module uses MMCX antenna connector with +2 dBi omni-directional gain and 3:1 VSWR max.
