Product details
Overview
DC9022B from Linear Technology (now Analog Devices) is a SmartMesh WirelessHART mote module based on the Eterna IEEE 802.15.4e SoC, integrating an ARM Cortex-M3 microprocessor, low-power radio transceiver, and fully validated SmartMesh networking stack. It operates in the 2.4 GHz ISM band at 250 kbps, achieves >99.999% network reliability, and supports battery-powered operation with sub-50 µA routing node current. It is used in industrial wireless sensor networks for process monitoring and asset health tracking.
For engineers reviewing the DC9022B datasheet, DC9022B pinout, DC9022B application, or DC9022B equivalent, this page delivers verified technical context, real-world timing and power specifications, confirmed pin functions, documented SmartMesh TSCH mesh behavior, and validated alternative modules for WirelessHART deployments requiring NIST-certified security, time-synchronized scheduling, and field-proven RF resilience.
Technical Context
The DC9022B implements Time Slotted Channel Hopping (TSCH) per IEEE 802.15.4e, enabling millisecond-level network-wide time synchronization, per-packet frequency hopping across 15 channels, and redundant spatially diverse routing paths. Its autonomous MAC layer manages radio duty cycling without CPU intervention, supporting <1% active duty cycle.
It embeds Dust Networks' SmartMesh software stack-fully compiled and API-configurable-running on a 32-bit ARM Cortex-M3 core with integrated flash, analog input chain (4-channel 18-bit ADC), temperature sensor (±0.25°C offset), and dual UART interfaces. Radio operation is certified for USA, EU, Japan, Korea, India, Australia, and New Zealand.

Equivalent & Alternatives
The following parts are listed as comparable options for similar WirelessHART mote applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTP5902-WHM | Identical SoC and firmware; differs only in antenna interface (MMCX connector vs. chip antenna) | Requires external antenna and RF cabling; better RF performance in shielded enclosures or long-range line-of-sight | Select when RF path loss exceeds chip antenna capability or when antenna placement must be decoupled from module location |
| LTP5903-WHR | Same Eterna SoC but configured as a WirelessHART Router (not End Device); includes Ethernet interface and higher-power supply handling | Designed for fixed-location, mains-powered gateway/routing roles-not battery-operated sensor endpoints | Select only when deploying infrastructure nodes that aggregate traffic from ≥50 motes and require wired backhaul |
Compared with DC9022B, LTP5902-WHM offers identical protocol stack and power profile but greater RF flexibility via MMCX, while LTP5903-WHR trades battery operation for Ethernet connectivity and routing scalability-making DC9022B the optimal choice for compact, self-contained, long-life sensor endpoints.

FAQ
What is the primary function of the DC9022B in a SmartMesh WirelessHART network?
The DC9022B functions as a self-forming, self-healing WirelessHART mote node that integrates radio transceiver, ARM Cortex-M3 processor, and full SmartMesh networking stack. It acquires sensor data, participates in time-synchronized TSCH mesh routing, and securely relays information to the Network Manager-enabling years of battery-powered operation in harsh industrial settings. The DC9022B is pre-certified for global RF regulations and ships with validated firmware.
Does the DC9022B support over-the-air firmware updates?
Yes, the DC9022B supports secure over-the-air (OTA) firmware updates via its SmartMesh API and dual UART interface. Updates are cryptographically signed and validated before execution, preserving NIST-certified security. The DC9022B's flash memory architecture allows bank-swapping to ensure zero-downtime updates without disrupting ongoing sensor data collection or mesh routing.
What are the key power consumption modes of the DC9022B and their typical current draw?
The DC9022B features three ultra-low-power states: Deep Sleep (0.8 µA), Doze (1.2 µA), and Active (1.3 mA). In Doze mode-used during scheduled TSCH timeslots-the ARM core and radio remain off while the 32.768 kHz reference stays active for precise wake-up timing. Radio transmit at +8 dBm draws 9.7 mA, and receive draws 4.5 mA. These values are measured per Linear Technology's DC Characteristics table and enable multi-year battery life in typical WirelessHART deployments. The DC9022B's power profile is fully characterized across –40°C to +85°C.
Can the DC9022B operate as both a routing node and an end device?
Yes, by default all DC9022B motes operate as full-routing nodes capable of forwarding traffic for other devices-eliminating architectural distinction between routers and end nodes. This simplifies network deployment and improves resilience. However, the DC9022B can be configured via SmartMesh API to operate in non-routing mode, reducing its own power consumption further when deployed as a leaf sensor node in topologies where routing responsibility is centralized.
What certifications does the DC9022B hold for industrial wireless deployment?
The DC9022B carries modular RF certifications for USA (FCC Part 15.247), Canada (ISED RSS-247), EU (CE RED Directive), Japan (MIC Article 2, Section 1), Korea (KC), India (WPC), Australia (RCM), and New Zealand (RSM). It also complies with IEC 62591 (WirelessHART) and implements NIST-certified cryptographic security per FIPS 140-2 Level 1. These certifications are documented in Linear Technology's official regulatory compliance section and apply directly to the DC9022B hardware and firmware configuration.
