Product Details

SmartMesh IP wireless sensor networks are self managing, low power internet protocol (IP) networks built from wireless nodes called motes.The LTP5902-IPM is printed circuit board assembly (PCBA) product with on-board chip antenna in the Eterna® family of IEEE 802.15.4e solutions, featuring a highly integrated, low power radio design as well as an ARM Cortex-M3 32-bit microprocessor running SmartMesh IP embedded networking software. The LTP5902-IPM, at 37mm × 24mm, is built for surface-mount assembly.

With SmartMesh IP time-synchronized networks, all motes in the network may route, source or terminate data, while providing many years of battery powered operation. SmartMesh IP is a highly flexible network with proven reliability and low power performance in an easy-to-integrate platform.

The LTP5902-IPM’s behavior in a SmartMesh IP network is determined by the choice of SmartMesh IP network software loaded: Wireless Mote, EManager, Access Point Mote in a SmartMesh IP network. The SmartMesh IP software provided with the LTP5902-IPM is fully tested and validated, and is readily configured via a software Application Programming Interface. Once you have purchased SmartMesh IP products, the SmartMesh IP stack binaries may be downloaded via your myAnalog account.

The pin signaling behavior of the LTP5902IPC-IPMA hardware is determined by the software loaded and is described in detail in the following product datasheets:

Network Features



>99.999% Network Reliability

Avoids communications dropouts common with other wireless networks

NIST-certified AES-128 bit Encryption

Data protected by end-to-end encryption, message integrity checking and device authentication


Uses time-slotted channel-hopping protocol to avoid in-network collisions to maximize scale while minimizing power and latency-hungry transmission retries due to congestion

Bidirectional Communications

Ideal for both monitoring and control applications

Up to 10 messages/second/node

Time-slotted communications avoids contention. This data rate includes built-in margin for packet retries.

Device Features



Industry-Leading Low Power Radio Technology

• 4.5mA to Receive a Packet
• 5.4mA to Transmit at 0dBm
• 9.7mA to Transmit at 8dBm

Pre-engineered RF

RF elements include an on-chip power amplifier and are pre-tuned for optimized performance, including temperature compensation, saving development time.

RF Modular Certifications

Pre-certified in USA, Canada, EU, Australia/New Zealand, India, Japan, Korea, Taiwan

Energy Harvesting Support

Very low power design enables motes to be powered by a wide variety of energy harvesters. Click here to see a demonstration circuit of a SmartMesh IP mote powered by indoor light.

Integrated Temperature Sensor

Precise temperature sensor is integrated directly into the mote.
