Additional I/O Model Support
The 5000 Series chips include hardware support for the Serial Peripheral Interface (SPI) and Serial
Communication Interface (SCI) serial I/O models, which provide increased performance for devices
that use these interfaces. The UART on the 5000 Series chips includes an increased FIFO (16 bytes),
and supports software-configurable parity generation and validation (odd, even, none).
Overall, the 5000 Series chips support 35 I/O models, including all of the I/O models that were
previously only supported by the PL 3120, PL 3150, and PL 3170 Smart Transceivers. These I/O
models include the Infrared Pattern model, Magcard Bitstream model, SCI model, and SPI model.
In addition, the 5000 Series chips support the Stretched Triac model, which is a new I/O model that
improves performance for triac devices used with inductive loads.
FT 5000 EVB Evaluation Board
The FT 5000 EVB is a complete 5000 Series L ON W ORKS device that you can use to evaluate the
L ON W ORKS 2.0 platform and create L ON W ORKS devices. The FT 5000 EVB includes a FT 5000
Smart Transceiver with an external 10 MHz crystal (you can adjust the system’s internal clock speed
from 5MHz to 80MHz), an FT-X3 communication transformer, 64KB external serial EEPROM and
flash memory devices, and a 3.3V power source. The FT 5000 EVB features a compact design that
includes the following I/O devices that you can use to develop prototype and production devices and
test the FT 5000 EVB example applications:
• 4 x 20 character LCD
• 4-way joystick with center push button
• 2 push-button inputs
• 2 LED outputs
• Light-level sensor
• Temperature sensor
The FT 5000 EVB Evaluation Board also includes EIA-232/TIA-232 (formerly RS-232) and USB
interfaces that you can use to connect the board to your development computer and perform
application-level debugging. You can also use the EIA-232 interface for development with the
ShortStack
®
Developer’s Kit. Note that only one interface can be used at a time.
Note: You cannot run ShortStack 2.1 Micro Servers on the FT 5000 EVB.
Each FT 5000 EVB also features a flash in-circuit emulator (ICE) header that supports the SPI and I 2 C
interfaces for fast downloads when programming the external non-volatile memory of the FT 5000
Smart Transceiver on the board.
For more information on the FT 5000 EVB hardware, including detailed descriptions of its Neuron
core, I/O devices, service pin and reset buttons and LEDs, and jumper settings, see the FT 50000 EVB
Hardware Guide.
Increased Network Variable Support
Neuron chips that use version 16 firmware or greater can support up to 254 static network variables
and 127 network variable aliases for Neuron-hosted devices, subject to available system resources (for
example, RAM and EEPROM) and application requirements. The 5000 Series chips use the new
version 18 Neuron firmware and therefore support these increased network variable limits, subject to
resources.
You must build the device application with the NodeBuilder FX tool to take advantage of these
increased network variable limits. If you use a previous release of the NodeBuilder tool, your device
application is limited to 62 network variables.
