FT Router 5000

The Router 5000 chip is used to build high performance half-routers that increase the scalability and survivability of LONWORKS® control networks and lower installation costs by allowing mixed physical media to be used in a single installation.

Key Features

  • 3.3V operation
  • Higher-performance Neuron® Core; internal system clock scales upto 40 MHz; Larger buffer size to allow for extended-NV sandim proved throughput
  • Serial interface for inexpensive-external non-volatile EEPROM and flash memories
  • Compliant with TP/FT-10
  • Channels
  • Low-cost surface mount FT-X3
  • Communications Transformer
  • Compact 7 mm x 7 mm 48-pin
  • QFN package
  • Logical Isolation between two half routers improves system reliability by isolating failures between channels
  • 40°C to +85°C operating temperature range
