14230R-450

Overview

The Renesas Electronics Corporation model 14230R-450 is the RoHS-compliant variant of the FT 3150 Free Topology Smart Transceiver. It integrates a Neuron 3150 network processor core with a twisted pair transceiver in a 64-lead TQFP package. The device supports a maximum input clock frequency of 20MHz and includes 0.5Kbytes of embedded EEPROM for configuration data, alongside 2Kbytes of embedded RAM for network variable buffering. It features an external memory interface capable of addressing up to 58Kbytes of additional memory. The component operates within a temperature range of -40°C to +85°C and complies with European Directive 2002/95/EC regarding hazardous substances.

Feature Summary

• Integrates a Neuron 3150 processor core with a free topology twisted pair transceiver for system-on-a-chip functionality
• Supports polarity insensitive wiring topologies including star, daisy chain, bus, loop, and mixed configurations
• Provides an external memory interface to address up to 58Kbytes of additional nonvolatile memory
• Features 11 I/O pins with 34 programmable standard modes to minimize external logic requirements

Applications

• Building automation systems
• Industrial control networks
• Transportation monitoring applications
• Utility metering infrastructure

Procurement Notes

Verify that the specific ordering suffix R-450 corresponds to the RoHS compliant version as documented in the official datasheet. Confirm that the required communication transformer (FT-X1 or FT-X2) is sourced separately, as the IC must be implemented together with these components to maintain warranty validity and ensure proper noise immunity performance.

Selection Notes

Select this model when application code size exceeds the 4Kbyte limit of the FT 3120 series but does not require the higher processing speed of newer cores. The FT 3150 architecture is specifically designed for cost-sensitive designs requiring external memory expansion via its dedicated bus interface. Ensure the design accommodates the 64-lead TQFP package dimensions and thermal dissipation requirements specified for the operating temperature range.

Part Context

This component belongs to the FT 3120 and FT 3150 Free Topology Smart Transceiver family developed by Echelon Corporation and distributed by Renesas Electronics. These devices are engineered to create low-cost smart transceivers on a chip for LonWorks compatible networks. The FT 3150 variant specifically targets applications needing larger memory capacity than the integrated EEPROM of the FT 3120 can provide.

Replacement Considerations

The RoHS compliant equivalent part number is 14230R-450. Non-RoHS versions include 14230-450. Direct functional replacements within the same family include the FT 3120 variants (e.g., 14210-500), though these lack the external memory interface and have different clock speeds.
