主な機能

  • Combines an ANSI/CEA 709.3-1999 compliant free topology twisted pair transceiver with a Neuron 3120 or Neuron 3150 network processor core
  • Supports polarity insensitive free topology star, daisy chain, bus, loop, or mixed topology wiring
  • 78 kilobits per second bit rate for distances up to 500 meters in free topology or 2700 meters in bus topology with double terminations
  • High performance Neuron network processor core enables concurrent processing of application code and network packets (40MHz maximum for FT 3120 smart transceiver, 20MHz maximum for FT 3150 smart transceiver)
  • 4Kbytes of embedded EEPROM for application code and configuration data on the FT 3120 smart transceiver and 0.5Kbytes of embedded EEPROM for configuration data on the FT 3150 smart transceiver
  • Interface for external memory for devices with larger memory requirements (FT 3150 smart transceiver only)
  • 2Kbytes of embedded RAM for buffering network data and network variables
  • 11 I/O pins with 34 programmable standard I/O modes minimizing external interface circuitry
  • Unique 48-bit Neuron ID in every device for network installation
