6 FT 5000 EVB Hardware Details
Introduction to FT 5000 EVB Hardware Details
The following sections provide additional details on the FT 5000 EVB hardware, including
descriptions of the core circuit, I/O devices, service and reset buttons and LEDs, and jumper settings.
You can view schematics for the peripheral circuitry of the FT 5000 EVB. The peripheral circuitry is
the section of the evaluation board external to the core circuit that is labeled CORE. To view the FT
5000 EVB schematics, click Start, point to Programs, point to Echelon NodeBuilder or Echelon
Mini, point to Documentation, and then click FT 5000 EVB Schematics.
Neuron Core
The Neuron core of 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, and a 64KB external serial EEPROM non-volatile memory device. For
details on the FT 5000 core, see the Series 5000 Chip Data Book.
In addition to the 64KB external serial EEPROM device in the Neuron core, the FT 5000 EVB
includes a 64KB external serial flash device. These serial EEPROM and flash memory devices are
used to store your application code, configuration data, and an upgradable system firmware image (the
Series 5000 chips have no user-accessible on-chip non-volatile memory). The external serial
EEPROM and flash memory devices communicate with the FT 5000 Smart Transceiver via the SPI or
I
2 C interfaces. The EEPROM device on the FT 5000 EVB uses the I 2 C interface; the flash device uses
the SPI interface. When a device is reset, the application code and configuration data are copied from
the external non-volatile memory into the 64 KB internal on-chip RAM, and the device application is
then executed.
