For Series 5000 chips, the default internal system clock speed

is 80.00 MHz (the crystal’s speed external clock speed of
10MHz multiplied by the default clock multiplier of 8), and it

may be as low as 5 MHz (10MHz * ½).

Note: The 5.00 MHz system clock setting is intended only to

facilitate backward compatibility with older designs that

cannot scale to higher clock rates. There is no power
consumption advantage to using 5.00 MHz over 10.00 MHz.
For Series 3100 chips, this is the same value as the External
Clock Speed
multiplied by ½.

Version

Select the Neuron firmware version for the selected Neuron

Chip or Smart Transceiver model. See your Neuron Chip or
Smart Transceiver data book for more information.
Select <Default> to use the default system image for the
chosen chip. The default system image is the most current

system image version included with this version of the Mini

kit and any applied service packs. If you are prototyping
devices, you typically select <Default>.
Select <Custom> to specify your own custom system image in

the Image Name property. See the Neuron C Programmer’s
Guide
for information on creating custom system images.
Select VerXX, where XX is the desired version number, to use
a specific system firmware version. After you have completed

the initial prototyping phase of your device's development and

you are beginning the testing or production phases, you should
select a specific system firmware version. This ensures that

further development and maintenance of your device is subject
to controlled conditions even when newer versions of the

system firmware become available.

Image Name

Displays the file name of the system image containing the
Neuron Firmware. If <Custom> is selected in the System

Image Version property, you can enter a system image file
name or click the button to the right and browse to a system

image symbol file (.sym extension).
For Series 5000 chips, the name of the default system image is
BFT5000.

Firmware Version Displays the Neuron Firmware version used by the selected

system image if the System Image Version property is set
to <Default>; otherwise N/A is displayed. This field is

read-only.

Setting Memory Properties

You can view and set the on-chip and off-chip memory properties for a hardware

template on the Memory tab of the Hardware Template Editor dialog. Figure B-3
displays the default memory properties for the FT 5000 Evaluation Board standard
