Echelon Series 6000 Chip databook - Manual (Page 68)

Transceiver is a 3.3 V part and the FT 3120 or FT 3150 Smart Transceiver is a 5 V part); the
packages are different; and the pinouts are different. In addition, if your Series 3100 device
uses a COMM_ACTIVE circuit to drive network-activity LEDs, the requirements for that
circuit are very specific for FT 3120 or FT 3150 Smart Transceivers, whereas for FT 6000
Smart Transceivers, you can use a simple LED driver circuit for the two network activity
LEDs.
See the FT 3120 / FT 3150 Smart Transceiver Data Book for more information about the
interface for FT 3120 or FT 3150 Smart Transceivers.
Comparison with Series 5000 Devices
For details of new features of the Series 6000 parts, please see What’s New for Echelon’s
Smart Transceivers and Neuron Chips
The pinout and packaging of both Series 5000 and Series 6000 parts are identical, thus
enabling a simple transition.
Comparison with the FTT-10A Transceiver
The FTT-10A transceiver is designed to be used with Neuron Chips (Series 3100, Series
5000, and Series 6000). The migration path from a Series 3100 Neuron Chip to a Series 3100
Smart Transceiver is fairly straightforward:
• The Series 3100 Smart Transceiver has the same footprint as the corresponding
Series 3100 Neuron Chip
• The FT-X1 transformer has the same footprint as the FTT-10A transceiver
• The pinout of the FT-X1 transformer is compatible with the connections between the
Series 3100 Neuron Chip and the FTT-10A transformer
See the FT 3120 and FT 3150 Smart Transceiver datasheet for more detailed information on
these pinouts and footprints.
A device based on a Series 3100 Smart Transceiver with the FT-X1 or FT-X2 transformer can
run the same applications with the same functionality as a 3100 Neuron Chip with an FTT-
10A transceiver. In addition, Series 3100 Smart Transceiver with the FT-X1, FT-X2, or FT-
X3 transformer has the same levels of transient immunity, but has improved magnetic field
noise immunity, and improved common-mode network noise immunity (as tested per EN
61000-4-6). See the FT 3120 / FT 3150 Smart Transceiver Data Book for more information
migrating from a 3100 Neuron Chip with an FTT-10A transceiver to a Series 3100 Smart
Transceiver with the FT-X1 or FT-X2 transformer.
The migration path from a Series 3100 Neuron Chip to a Series 6000 Smart Transceiver
requires additional design work:
• The Series 6000 Smart Transceiver is a 3.3 V part and the Series 3100 Neuron Chip
is a 5 V part
• The Series 6000 Smart Transceiver has a different footprint compared to the
corresponding Series 3100 Neuron Chip
• The FT-X3 transformer has a different footprint compared to the FTT-10A
transceiver
• The pinout of the FT-X3 transformer is not entirely compatible with the connections
between the Series 3100 Neuron Chip and the FTT-10A transformer
