1. Introduction
The LPCXpresso™ family of boards provides a powerful and flexible development
system for NXP's LPC Cortex®-M family of MCUs. They can be used with a wide range
of development tools, including NXP’s MCUXpresso IDE. The LPCXpresso54608
(OM13092) / LPCXpresso54618 (OM13094) / LPCXpresso54S618 (OM13095) share the
same design and have been developed by NXP to enable evaluation of and prototyping
with the LPC546xx family of MCUs. There is no functional difference between these
boards except the (1) functionality of the LPC546xx device installed, and (2) that the
LPC54618 board does not include the LCD panel. All boards use a BGA180 package.
The schematics show that the board was designed for either 1.8 V or 3.3 V build
configurations, but all production boards are built in the 3.3 V configuration.

(1) Red is used to highlight key components, brown for buttons and LEDs, green for connectors and blue for expansion
connectors.
Fig 2. LPCXpresso546xx main feature layout
The LCD panel is mounted on the reverse side of the board, connected to the circuitry
via two flex cable connectors. It should not normally be necessary to remove the LCD or
access these connectors; the LCD is held in place by 4 double-sided adhesive pads.

JP1
Target processor selection for the on-board debug probe.
Jumper open (default) the LPC546xx Target SWD interface
enabled. Normal operating mode where the Target SWD is
connected to either the on-board Link2 debug probe or an external
debug probe.
Jumper shunted, the LPC546xx Target SWD interface is disabled.
Use this setting only when the on-board Link2 debug probe is used
to debug an off-board target MCU.

For On-board Target place in position 1-2 (default)
For Off-board Target place in position 2-3
3, 4
JP3
This header (not installed by default) provides a convenient
connection point to provide external ADC positive and negative
voltages. To inject these voltages at this header SJ22 (for VREFN)
and/or SJ23 (for VREFP) need to be moved from the default 1-2
position to the 2-3 position.
See
Schematic
JP4
This set of 3 jumpers control various selections for power
measurement:
Position 1-2 and 3-4 are in parallel with 1 ohm resistors. Current
can be measured across these jumper headers to determine
current flow into the LPC546xx target.
Position 5-6 (installed by default) can be left open and a current
meter connected between these pins to directly measure current
flow into the LPC546xx target.
JP5
Link2 (LPC43xx) force DFU boot –2 position jumper pins.
1) Jumper open (default) for Link2 to follow the normal boot
sequence. The Link2 will boot from internal flash if image is found
there. With the internal flash erased the Link2 normal boot
sequence will fall through to DFU boot.
Jumper shunted to force the Link2 to DFU boot mode. Use this
setting to reprogram the Link2 internal flash with a new image
(using the LPCScrypt utility) or to use the MCUXpresso IDE with
CMSIS-DAP protocol.
Note that the LPCXpresso546xx Link2 flash is pre-programmed
with a version of CMSIS-DAP firmware by default.
JP6
Bridge / Host Expansion Header selector.
Revision B boards:
When open (default), the SPI connections from Flexcomm3 the
LPC546xx are driven to the Link2 debug probe.
Install JP6 when using the SPI interface at connector J14. Note
that this disables the Link2 SPI (bridge) probe connection.
Revision C boards:
When open (default), the “Bridge” UART and SPI connections from
the Link2 probe are driven to the LPC546xx target.
Install JP6 when using the SPI interface at connector J14 and/or
FC0 UART at P4 (FTDI). Note that this disables the Link2 SPI and
UART (bridge) probe connections.
JP7
(not
installed by
default)
JP7 may be fitted to provide a convenient way to enable/disable
the reset signal to/from the expansion connectors. Solder jumper
JS28 should be removed if JP7 is to be used.

Description
Section
JP8
This set of jumpers is used to configure 3.3V vs 1.8V board
configurations. OM13092 boards are all 3.3V, so these jumpers
should not be changed from the default.
JP8 is not present on Revision C boards (functionality has been
replaced by zero ohm links).
See
schematic
JP9
USB host Vbus selection
Note that only one of USB0 or USB1 can be configured as a USB
host port at any given time (this is a board restriction, not a
limitation of the LPC546xx.)
Install jumper in position 1-2 for USB1 (High Speed) to provide
Vbus (i.e. enable USB host capability) (Default)
Install jumper in position 2-3 for USB0 (Full Speed) to provide Vbus
(i.e. enable USB host capability)
JP10
USB host power control selection
This jumper selects routing of USB port power and overcurrent
detect from either the USB0 or USB1 ports of the LPC546xx. Note
that only one of USB0 or USB1 can be configured as a USB host
port at any given time (this is a board restriction, not a limitation of
the LPC546xx.)
Leave open when using USB1 (High Speed) as a USB host
(Default)
Install jumper for USB0 (Full Speed) to provide Vbus (i.e. enable
USB host capability)
JP11 &
JP12
USB0 host / Ethernet TXD/RXD selection
Due to sharing of pin functionality on this development board, it is
not possible to support the Ethernet port and USB0 overcurrent
feature simultaneously. For both JP11 and JP12:
Install jumper in position 1-2 to enable Ethernet (Default)
Install jumper in position 2-3 for USB0 (Full Speed) (i.e. enable
USB host capability)
JP13
USB0 host / Ethernet selection
Due to sharing of pin functionality on this development board, the
P4-7 port pin is used for either the USB0 port or as a general
purpose signal on the expansion connector.
Install jumper in position 1-2 to route P4-7 to the expansion
connector.
Install jumper in position 2-3 for USB0 (Full Speed) (i.e. enable
USB host capability)
Table 2 describes the board LED and button functions, and connectors.
