Analog Devices Inc. DC2274A-A

Overview

DC2274A-A from Analog Devices (formerly Linear Technology) is a SmartMesh® IP Network Manager evaluation board for the LTP5901-IPR and LTP5902-IPR wireless sensor network modules. It integrates an ARM Cortex-M3 microprocessor, IEEE 802.15.4e radio transceiver, and preloaded SmartMesh IP networking software to enable time-synchronized, self-healing mesh networks with >99.999% reliability, sub-50µA routing node current, and NIST-certified security. It serves as a UART-connected ingress/egress point for industrial wireless sensor networks.

For engineers reviewing the DC2274A-A datasheet, DC2274A-A pinout, DC2274A-A application, or DC2274A-A equivalent, this page delivers verified technical context, real-world timing and power specifications, validated alternative evaluation platforms, and supply-chain-ready availability details - all grounded in official Analog Devices documentation and hardware design files.

Technical Context

The DC2274A-A implements the LTP5901-IPR/LTP5902-IPR module in a fully assembled, tested PCB form factor with onboard USB-to-UART bridge, debug interface, and chip antenna (LTP5901-IPR variant) or MMCX connector (LTP5902-IPR variant). It supports TSCH (Time-Slotted Channel Hopping) link-layer operation per IEEE 802.15.4e, enabling millisecond-level network-wide time synchronization and per-transmission frequency hopping.

It exposes dual UART interfaces (API and CLI), RADIO_INHIBIT control, TIMEn time-stamping signal, and external bus signals (EB_DATA, EB_ADDR, EB_IO_LEx) for host integration. The board operates across –40°C to +85°C and supports flash programming via SPI slave interface with guaranteed 100-year data retention at 25°C.

FAQ

What is the primary function of the DC2274A-A evaluation board?

The DC2274A-A evaluation board serves as a ready-to-use SmartMesh IP Network Manager platform for the LTP5901-IPR and LTP5902-IPR modules. It enables rapid prototyping and validation of time-synchronized, self-healing 2.4GHz mesh networks. The DC2274A-A provides UART-based host connectivity, on-board debugging, and pre-flashed SmartMesh IP firmware - allowing engineers to immediately configure, monitor, and manage up to 100-node networks without custom hardware design.

Does the DC2274A-A support both LTP5901-IPR and LTP5902-IPR modules?

Yes, the DC2274A-A is designed to accommodate both the LTP5901-IPR (with integrated chip antenna) and LTP5902-IPR (with MMCX RF connector) modules. Its mechanical layout and signal routing are compatible with either variant's 66-pin footprint and pinout. Users select the appropriate module based on antenna requirements - chip antenna for compact sealed deployments or MMCX for external high-gain or directional antennas - while retaining identical software, timing, and power behavior on the DC2274A-A.

What communication interfaces does the DC2274A-A expose for host integration?

The DC2274A-A exposes two UART interfaces (API UART and CLI UART), a dedicated TIMEn time-stamping signal, RADIO_INHIBIT control line, and full external bus signals (EB_DATA[7:0], EB_ADDR[1:0], EB_IO_LE0–LE2, EB_IO_CS0n, EB_IO_OEn, EB_IO_WEn). These allow direct connection to host microcontrollers or FPGAs for embedded integration beyond USB-UART. The API UART supports structured command/response protocols for network configuration and data exchange, while the CLI UART enables interactive diagnostics and firmware updates.

How does the DC2274A-A achieve >99.999% network reliability?

The DC2274A-A achieves >99.999% network reliability by hosting the LTP5901-IPR/LTP5902-IPR module running Dust Networks' SmartMesh IP software stack, which implements Time-Slotted Channel Hopping (TSCH) per IEEE 802.15.4e. This includes millisecond-level time synchronization across all nodes, per-packet frequency hopping, redundant spatially diverse routing paths, and autonomous MAC-layer retransmission. The DC2274A-A itself acts as the central manager that continuously optimizes schedules and routes using health report telemetry - ensuring resilience against interference, obstruction, and fading without manual intervention.

Is the DC2274A-A suitable for battery-powered operation?

Yes, the DC2274A-A supports battery-powered operation when used with the LTP5901-IPR or LTP5902-IPR modules, which draw only sub-1mA average current during active network management and as little as 0.8µA in deep sleep mode with full RAM and state retention. While the evaluation board includes USB power options, its underlying module architecture is explicitly designed for multi-year battery life - demonstrated by sub-50µA routing node current and <1% duty cycle operation enabled by TSCH scheduling. Engineers can validate true battery longevity using the DC2274A-A's low-power modes and current measurement test points.
