14305R-500

Overview

The Neuron 5000 Processor (14305R-500) is a system-on-chip designed for LonWorks control networks, integrating communication and control functions. It features a high-performance Neuron Core with an internal clock scaling up to 80 MHz, supporting up to 254 network variables. The device includes 64KB RAM (44KB user-accessible), 16KB ROM, and 12 bidirectional I/O pins. It operates at 3.3V with 5V-tolerant inputs and supports external serial EEPROM and flash memory via SPI or I2C interfaces.

Feature Summary

• Neuron Core with hardware multiplier/divider and internal clock up to 80 MHz
• Supports up to 254 Network Variables and 127 aliases
• Integrated 5-pin communications port compatible with various transceivers
• On-chip memories: 64KB RAM and 16KB ROM

Applications

• LonWorks control network devices
• Industrial automation systems
• Building management systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range. Ensure compatibility with required external memory configurations and transceiver types before procurement.

Selection Notes

Select this processor for applications requiring backward compatibility with Series 3100 Neuron Core software while needing higher performance. Consider the need for external non-volatile memory for application code storage, as the chip lacks on-chip user-accessible NVM.

Part Context

The 14305R-500 is part of the Neuron 5000 Processor series, succeeding the Neuron 3120 and 3150 chips. It provides enhanced performance through a faster clock speed and additional instructions while maintaining source code compatibility with previous generations using NodeBuilder FX tools.

Replacement Considerations

Direct replacement for Neuron 3120/3150 requires hardware redesign due to voltage and memory architecture differences. Use FT 5000 Smart Transceiver for TP/FT-10 channels or appropriate transceivers for other media types.
