3.4.1
Evaluation Kit Part Number
This displays the evaluation kit part number, EV20F92A.
3.4.2
Firmware Version
This is the version of the firmware programmed in the USB Base Board.
3.4.3
Evaluation Kit Protocol
Identifies the communication protocol used by the evaluation kit’s socket board.
3.4.4
Serial Number
The SPI Socket Board serial number is retrieved from the AT24CS02 serialized Serial
EEPROM located on the SPI Socket Board. Every SPI Socket Board will have its own
unique serial number.
3.5
DEVICE CONDITIONS
The Device Conditions pane (
) allows the user to set the supply voltage to
the SPI Socket Board and the communication speed or frequency of the SPI protocol.

3.5.1
Supply Voltage Slider
The voltage slider provides the ability to change the supply voltage, in 100 mV
increments, to the SPI Socket Board, including the installed device V
CC
voltage. The
user can change the V
CC
by either clicking along the slider or dragging the indicator to
the desired V
CC
. The upper and lower limits of the V
CC
are determined by the installed
device specification. Because the supply voltage is common between every device on
the SPI Socket Board, a test point is included to measure V
CC
. Whenever the GUI is
initially started or a Device Query is performed, the voltage slider will default to the
lowest supported V
CC
of the installed device.
3.5.2
Frequency Slider
The frequency slider provides the ability to change the frequency communication
speed between the host controller (USB Base Board) and the installed device. The
user can change the speed by either clicking along the slider or dragging the indicator
to the desired frequency. The upper frequency limit of the communication speed slider
is determined by the installed device specification. Whenever the GUI is initially started
or a Device Query is performed, the frequency slider will default to 1 MHz to ensure the
installed supported device is able to communicate with the host controller.
