Product details
Overview
LTP5900-WHM from Analog Devices (acquired Linear Technology) is a SmartMesh WirelessHART mote module integrating IEEE 802.15.4 radio, ARM Cortex-M3 microprocessor, and embedded WirelessHART networking stack. It operates in 2.400–2.4835 GHz band, delivers >99.999% network reliability, achieves sub-50 µA routing node current, and supports NIST-certified 128-bit AES encryption for industrial wireless sensor networks.
For engineers reviewing the LTP5900-WHM datasheet, LTP5900-WHM pinout, LTP5900-WHM application, or LTP5900-WHM equivalent, key selection criteria include time-synchronized mesh topology support, dual UART/serial interface modes (9600 bps Mode 1 or 115.2 kbps Mode 3), MMCX antenna interface, 22-pin PCB package, and compliance with IEC 62591 WirelessHART standard.
Technical Context
The LTP5900-WHM implements a time-synchronized, frequency-hopping mesh network using IEEE 802.15.4e MAC and PHY layers, with per-transmission channel hopping across 15 channels at 250 kbps raw data rate. Its embedded SmartMesh software handles network formation, self-healing, and spatially diverse redundant routing without external host intervention.
It integrates a voltage supervisor (1.5 V trip point), on-board temperature sensor (±7°C accuracy), and dual-mode serial interface controlled by MODE_PIN_B. Power management enables deep sleep with wake-on-RST and low-power operation down to 4.5 mA receive current and 5.4 mA transmit current (PA disabled).

Pinout & Package
22-pin PCB assembly (39 mm × 24.4 mm) with MMCX antenna connector, designed for surface-mount integration into industrial sensor enclosures. Pin functions are defined per IEEE 802.15.4E-compliant serial interface and power management logic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS (Pin 1) | Ground reference | Primary power return path; must be low-impedance connection to system GND plane. |
| VDD (Pin 2) | Power supply input | Accepts 2.75–3.76 V; requires 6 µF total capacitance and 4.9 µH inductance for stable RF operation. |
| RX (Pin 4) | UART receive input | Asynchronous serial data from host MCU; TTL-level, 9600/115.2 kbps configurable. |
| TX (Pin 5) | UART transmit output | Drives host MCU RX; active-high logic; supports HDLC framing with 0x7E delimiters. |
| MT_RTS (Pin 7) | Mote-ready-to-send signal | Active-low wake-up signal to host MCU before packet transmission; essential for low-power host sleep coordination. |
| MT_CTS (Pin 8) | Host-clear-to-send output | Indicates mote readiness to accept host packets; de-asserted when network disconnected or buffer full. |
| SP_CTS (Pin 9) | Serial-peripheral clear-to-send input | Enables packet-level (Mode 1) or byte-level (Mode 3) flow control from host to prevent UART overrun. |
| TIME (Pin 10) | Timestamp trigger input | Falling-edge-activated; captures synchronized network time within ~1 ms; optional but improves timestamp accuracy vs. HDLC request. |
| MODE_PIN_B (Pin 11) | Interface mode select | Low = Mode 1 (9600 bps, 3–5 signal); High = Mode 3 (115.2 kbps, 5-signal with byte-level flow control). |
| RST (Pin 22) | Active-low hardware reset | Internally pulled up; assertion forces full boot sequence; recommended only after graceful disconnect command (0x07). |

FAQ
What is the primary function of the LTP5900-WHM in an industrial wireless sensor network?
The LTP5900-WHM serves as a fully integrated WirelessHART mote node, combining radio transceiver, ARM Cortex-M3 processor, and certified SmartMesh networking software. It forms self-healing, time-synchronized mesh networks for reliable sensor data collection in harsh environments. The LTP5900-WHM handles routing, timing synchronization, security, and protocol compliance without external host intervention - making it a turnkey solution for industrial IoT deployments.
Does the LTP5900-WHM require external programming before use?
Yes, the LTP5900-WHM ships with flash memory erased and requires firmware programming during manufacturing. Analog Devices provides the DC9010 in-circuit programmer and SmartMesh software images via MyLinear portal after registration. The LTP5900-WHM cannot operate without loaded WirelessHART stack and application firmware; no factory-default operational mode exists.
How does the LTP5900-WHM achieve >99.999% network reliability?
The LTP5900-WHM achieves ultra-high reliability through three coordinated mechanisms: time-synchronized network-wide scheduling eliminates collisions; per-packet frequency hopping across 15 channels mitigates narrowband interference; and spatially diverse redundant topologies automatically reroute around failed links. These features are implemented in the embedded SmartMesh software and validated per IEC 62591. The LTP5900-WHM demonstrates this reliability in live refinery and power plant deployments.
Can the LTP5900-WHM operate without an external antenna?
No - the LTP5900-WHM requires an external 50 Ω antenna connected via its onboard MMCX female connector. The module has no integrated antenna; RF performance depends entirely on antenna selection and placement. The datasheet specifies maximum VSWR of 3:1 and mandates vertical orientation with radiating element protruding from metal enclosures. Operating without an antenna violates absolute maximum ratings and risks permanent damage to the RF front-end.
What are the key differences between Mode 1 and Mode 3 serial interfaces on the LTP5900-WHM?
Mode 1 uses 9600 bps with optional 3–5 signal UART (RX/TX/MT_RTS/MT_CTS/SP_CTS) and packet-level flow control - ideal for low-pin-count, ultra-low-power hosts. Mode 3 uses 115.2 kbps with mandatory 5-signal UART and adds byte-level SP_CTS flow control for high-throughput diagnostics. Selection is controlled by MODE_PIN_B (low = Mode 1, high = Mode 3). Both modes support TIME-triggered timestamps and HDLC framing, but only Mode 3 enables real-time firmware updates over serial.
