FT3120 Datasheet, PDF (1/16 Pages) List of Unclassifed Manufacturers – Topology Smart Transceivers

FT 3120® and FT 3150® Free
Topology Smart Transceivers
FT 3120 transceiver in a 44-pin TQFP
package[1]
Features
• 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 pro-
cessing 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 in-
terface circuitry
• Unique 48-bit Neuron ID in every device for network installation and manage-
ment
• Compact external transformer with patent pending
architecture providing exceptional immunity from magnetic interference and
high frequency common mode noise
• Compatible with TP/FT-10 channels using FTT-10 and/or FTT-10A Free Topol-
ogy Transceivers and, with suitable DC blocking capacitors, LPT-10 Link
Power Transceivers
• Communications parameters preprogrammed for the TP/FT-10 channel at
10MHz
• 5V operation with low power consumption
• -40 to +85°C operating temperature range[3, 4
