Echelon LonWorks Twisted Pair Control Module - Manual (Page 3)

LonWorks Twisted Pair Control Module User's Guide iii
Welcome
Echelon’s L ON W ORKS ® Twisted Pair Control Modules contain the core elements
for device designs using L ON W ORKS technology. The core elements of a control
module are an FT 5000 Smart Transceiver or Neuron ® 3150 ® Chip, crystal clock
circuit, I 2 C EEPROM or JEDEC MO-052 AE PLCC memory socket (32-pin
rectangular), Communications Transformer or twisted pair transceiver, and
unbuffered access to the I/O, SERVICE~, and RESET~ signals.
All of the Neuron 3150 L
ON W ORKS Twisted Pair Control Modules share a
common footprint and I/O interface to allow systems with different media
requirements to share common application electronics board designs. The FT
5000 Control Module has a similar I/O interface so that you can easily modify
designs that use a Neuron 3150 Control Module to use the FT 5000 Control
Module.
Table 1 lists the available modules.
