JP15
‘GND’
Jumper: security fuse
control
This jumper should be removed at all times.
Connecting the jumper will allow the security fuses
to be blown under firmware control. Refer to the
73S1215F Data Sheet for further information
about the security fuse.

J1, J4
SIM / SAM and Smart
Card connectors –
internal interface (#1)
Allows the evaluation board to communicate with a
smart card using either the standard (credit card
size) or SIM/SAM format: This slot is connected to
the 73S1215F built-in card interface # 1.
J1 is wired in parallel to the smart card connector
J4 (underneath the PCB). Both connectors cannot
be used at the same time.

R24 - R33
Jumper resistors
These jumper resistors will configure the board for
a 73S1215F device. U3 should not be populated.

JP1
‘VOUT’
Jumper:
power supply selection
(#2)
This jumper selects the 5.0 V power supply. It
selects either the power supply connected to the
on-board 5.0 V regulator (U1) or the 5.0 V from the
external regulated supply/USB VBUS (see item
39):
•
In position “VOUT”, the evaluation board 5.0 V
is powered from the on-board +5 V regulator.
•
In position “5V”, the evaluation board, is
powered from the voltage applied on the plug
J2.

JP5
‘VBUS’
Jumper:
power supply selection
(#3)
This jumper selects the 5.0V power supply. It
selects either the power supply connected to plug
J2 or the USB VBUS 5.0V:
•
In position “VBUS”, the evaluation board +5 V
going to JP1 is connected to the +5 V coming
from the USB.
•
In position “5VEXT”, the evaluation board is
powered from the voltage applied on the plug
J2.
