Product details
Overview
14450R-500 from Echelon is a Smart Transceiver SoC integrating a Neuron® core, Free Topology twisted-pair transceiver, and three independent 8-bit processors (MAC, NET, APP) for LONWORKS®, IzoT™, BACnet/IP, and Any IP-over-FT operation. It operates at 3.3 V, supports 80 MHz system clock, 64 KB RAM, 16 KB ROM, and 12 programmable I/O pins - deployed in building automation, industrial control, and smart infrastructure networks.
For engineers reviewing the 14450R-500 datasheet, 14450R-500 pinout, 14450R-500 application, or 14450R-500 equivalent, key selection criteria include native IP addressing capability, four-mode protocol support (LonTalk Stack/BACnet/IP/Any IP over FT), polarity-insensitive free topology wiring, IEEE MAC ID uniqueness, and compatibility with FT-X3 transformer-based noise-immune physical layer design.
Technical Context
The 14450R-500 implements a tri-processor architecture: dedicated MAC CPU handles physical-layer framing and 1280-byte frame support; NET CPU manages LonTalk/BACnet/IP protocol stacks and address translation; APP CPU executes user Neuron C code. An optional IRQ CPU handles interrupts at higher clock rates.
It supports all four operational modes - LonTalk Stack over FT, LonTalk/IP Stack over FT, BACnet/IP over FT, and Any IP over FT - with full TP/FT-10 channel compliance and backward compatibility to FTT-10A, FT 3120/3150, and LPT-10/11 devices. Firmware version 21+ is required and loaded from external SPI flash.

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 14410R-500 (FT 6010) | Omits LonTalk Stack over FT mode; supports only LonTalk/IP, BACnet/IP, and Any IP over FT. | Cannot replace legacy LONWORKS-only nodes requiring full LonTalk stack execution. | Select when IP-native operation is mandatory and backward compatibility with pure LonTalk devices is not required. |
| FT 3150-1000 | 10 MHz clock, 2 KB RAM, no IP stack, no IRQ CPU, requires external EEPROM, 44-pin PLCC package. | Limited to LonTalk-only operation; lacks native IP addressing and modern memory architecture. | Choose only for cost-sensitive brownfield upgrades where existing firmware and toolchain must be retained without recompilation. |
Compared with 14410R-500 and FT 3150-1000, the 14450R-500 uniquely delivers full four-mode protocol flexibility, 80 MHz deterministic performance, and scalable flash-based storage - making it the only option for greenfield IIoT deployments requiring both legacy interoperability and future-proof IP convergence.

FAQ
What communication protocols does the 14450R-500 support?
The 14450R-500 supports four distinct operational modes: LonTalk Stack over FT (full LONWORKS® compatibility), LonTalk/IP Stack over FT (native IP addressing with LonTalk services), BACnet/IP over FT (LONMARK®-to-BACnet object mapping), and Any IP over FT (custom protocol transport). All modes operate over the same Free Topology twisted-pair physical layer and share identical hardware resources.
Does the 14450R-500 require an external communications transformer?
Yes - the 14450R-500 must be used with the FT-X3 Communications Transformer (e.g., 14255R-100) or legacy FT-X1/FT-X2 transformers. The FT-X3 is polarity-insensitive and provides EN 61000-4-6 Level 3 common-mode noise immunity. Using any other transformer voids the smart transceiver warranty and compromises noise performance.
What firmware version is required for the 14450R-500?
The 14450R-500 requires Neuron firmware version 21 or later. Firmware versions prior to 21 are incompatible and will not boot. The firmware is loaded from external SPI flash memory at reset and can be upgraded over the network or via in-circuit programming - no on-chip NVM is used for firmware storage.
How many I/O pins does the 14450R-500 provide, and what are their capabilities?
The 14450R-500 provides 12 bidirectional, 5V-tolerant I/O pins configurable in 35 predefined models including edge-triggered interrupts, PWM outputs, pulse counting, analog input emulation, and open-drain drive. Each pin supports user-defined interrupt conditions, enabling responsive event-driven control without polling overhead.
Is the 14450R-500 pin-compatible with earlier FT-series transceivers?
No - the 14450R-500 uses a 48-pin QFN package, whereas FT 3120/3150 use 44-pin PLCC and FT 5000 uses 48-pin LQFP. Pin assignments, power sequencing, and JTAG interface behavior differ. Migration requires PCB redesign and firmware recompilation using IzoT NodeBuilder Software, though Neuron C source code remains compatible.
