BOARD FEATURES
Power Supply
The ADZS-U4050LF-EZKIT evaluation board can be powered
by numerous sources to evaluate the capability of the
ADuCM4050
microcontroller.
The following sources are the options for powering the board:
External power supply. The ADZS-U4050LF-EZKIT board
package has a 5 V dc regulated power adapter included. To
use the adapter to supply the microcontroller, Pin 3 and
Pin 5 of JP12, and Pin 1 and Pin 3 of JP14 must be shorted;
then, connect the adapter to the P8 power jack.
J-Link LITE emulator. The J-Link LITE emulator can power
the evaluation board while debugging and programming
the microcontroller. Pin 1 and Pin 3 of JP12 and Pin 1 and
Pin 3 of JP14 must be shorted to use this option. To power
the board by this option, the user must also command the
J-Link LITE to power on the board. Run the J-Link LITE
commander, and then execute the
power on perm
command.
USB power supply. The ADZS-U4050LF-EZKIT board can
draw power from the USB to the UART port on the lower
right side of the board. The configuration for this setup is
shorting Pin 3 and Pin 4 of JP12 and Pin 1 and Pin 3 of JP14.
USB mbed. The ADZS-U4050LF-EZKIT board can draw
power from the USB to the mbed interface on the lower
side of the board. The jumper configuration is the same as
the previous one.
Coin cell battery. The ADZS-U4050LF-EZKIT board can be
powered by a 3 V coin cell battery (included in the kit). To
use the coin cell battery, Pin 1 and Pin 2 of JP16 and Pin 3
and Pin 4 of JP14 must be shorted.
AA battery. To use an AA battery, Pin 2 and Pin 3 of JP16
and Pin 3 and Pin 4 of JP14 must be shorted.
Photovoltaic (PV) cell. The ADZS-U4050LF-EZKIT board
can be also be powered by energy harvesting kits provided
by Analog Devices, Inc. To use this option, Pin 3 and Pin 5
of JP14 must be shorted.
The configurations for the power options are listed in Table 2.
The pin numbers indicate the pins to be shorted.
