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 LPCXpresso54S018M
development board has been developed by NXP to enable development with the
LPC54S018JxM and LPC54018JxM family devices. It is very similar to the
LPCXpresso54S018 design, with only a few minor modifications to accommodate the
differences between these two series of devices. The board uses an LPC54S018J4M in
a BGA180 package.
The LPCXpresso54S018M can provide CAN-FD support when combined with the
OM13099 CAN-FD shield or using external transceivers connected via the available
expansion site connectors.

3. Getting Started
The LPCXpresso54S018M board is pre-programmed with a spirit level demonstration
and self-test diagnostic program. The spirit level demonstration uses the User LEDs and
on-board accelerometer. Connect a micro USB cable from connector J1 to a power
source (computer or power supply), place the board on a flat surface, and the 3 User
LEDs will all light; tilting the board (rotating about the axis of the horizontal center of the
board) will cause the LED pattern to change to illustrate the angle of tilt.
The pre-programmed application also includes a suite of self-test functions. Please see
Section 4 for full details of that application.
3.1 Starting a debug session using the on-board (Link2) Debug Probe
By default, the LPCXpresso54S018M is configured to use the on-board Debug Probe
(Link2) to debug the on-board target (LPC54S018J4M), using the CMSIS-DAP debug
protocol pre-programmed into the Link2 Flash memory. The MCUXpresso IDE or other
development tools that support the CMSIS-DAP protocol can be used in the default
configuration.
Note that when using the MCUXpresso IDE, the on-board Link2 can also be booted in
DFU mode by installing a jumper on JP5; if this is done then the IDE will download
CMSIS-DAP to the probe as needed. Using DFU boot mode will ensure that the most upto-date / compatible firmware image is used with the MCUXpresso IDE. Note that spare
jumpers are provided in the board packaging.
NOTE: if the Debug Probe is set up to boot in DFU mode, the USB bridge functions
(virtual comm port) and Debug Probe features will not be available if the board is not first
initialized by the MCUXpresso IDE.
For further information and tutorial videos please visit the Getting Started tab on the
https://www.nxp.com/demoboard/LPC54S018M-EVK board page.
3.1.1 Installation steps for use with MCUXpresso IDE
1. Download and install the MCUXpresso IDE.
2. Configure and download an SDK package (with the MCUXpresso IDE tool chain
option selected) from the MCUXpresso SDK Builder utility
(http://mcuxpresso.nxp.com), or use the pre-built example available in the online
Getting Started Guide tutorial.
3. Start the IDE, using a new or already created workspace. Drag and drop the SDK
package zip file into the Installed SDK panel at the bottom right of the IDE.
4. In the Quickstart panel at the bottom right of the IDE, select “Import SDK
example(s)…”. Select the board you are using in the dialog that appears, click Next
then select example(s) from the demo_apps or driver_examples, then click Finish.
5. Click on the project you imported in the Project Explorer at the left panel in the IDE,
the click “Build” in the Quickstart panel. Monitor the Console window at the bottom
right panel of the IDE to see the build process complete.
6. Recommended: Install JP5 to force the Link2 Debug Probe to boot in DFU mode
before powering the board (see notes above).

7. Ensure jumper JP2 is fitted in position 1-2 (local target powered), and JP1 is not
installed (target SWD enabled). These are the default positions set during board
manufacture.
8. Connect the LPCXpresso54S018M board to the USB port of your host computer by
connecting a micro USB cable to connector J8 (“USB Debug-Link”). The board will
boot and run the pre-installed demo.
9. Allow about 10 seconds for the LPCXpresso54S018M devices to enumerate for the
first time; the device will appear as “LPC Device” in the host computer system (if
booted in DFU mode).
10. In the Quickstart panel of the IDE, click “Debug”. The IDE will search for the board;
once a dialog appears showing the board has been found, click OK to connect and
start the debug session.
11. If the first attempt to debug a project fails in the IDE, cancel the debug session and
repower the board. On some machines the drivers take longer to enumerate for the
first time, so these steps should correct this issue.
The board is now ready to be used with the MCUXpresso SDK examples in the package
you have loaded. For more information on the MCUXpresso tool suite, including video
tutorials, please visit https://www.nxp.com/mcuxpresso.
When the board has been running applications that use the EMC port, it is recommended
to force the LPC54S018J4M target into a known state by performing an ISP boot before
attempting to run your first example code. This can be achieved by pressing and holding
down the ISP0 button while applying power to the board.
3.1.2 Installation steps to use Keil and IAR tools
1. Download and install LPCScrypt or the Windows drivers for LPCXpresso boards
(http://www.nxp.com/lpcutilities). This will install required drivers for the board.
2. Ensure JP5 is open to force the Link2 Debug Probe to boot from internal flash.
3. Ensure jumper JP2 is fitted in position 1-2 (local target powered), and JP1 is not
installed (target SWD enabled). These are the default positions set during board
manufacture.
4. Connect the LPCXpresso54S018M board to the USB port of your host computer,
connecting a micro USB cable to connector J8 (“USB Debug-Link”). The board will
boot and run the pre-installed demo.
5. Allow about 10 seconds for the LPCXpresso54S018M devices to enumerate for the
first time. It is not necessary to check the Hardware Manager, however if this is done
there will be five devices; four under Human Interface Devices (CMSIS-DAP, LPCSIO, two HID Compliant Devices, and a USB Input Device) and one under Ports
(LPC-LinkII Ucom.)
6. Your board is now ready to use with your 3rd party tool. Follow the instructions for
those tools for using a CMSIS-DAP probe.
When the board has been running applications that use the EMC port, it is recommended
to force the LPC54S018J4M target into a known state by performing an ISP boot before
attempting to run your first example code. This can be achieved by pressing and holding
down the ISP0 button while applying power to the board.

3.2 Starting a debug session using an external Debug Probe
Code running on the LPC54S018J4M target can be debugged using an external Debug
Probe that conforms to the standard ARM debug connector. To use an external Debug
Probe connect the probe to the SWD connector (P1) and connect power via the micro
USB connector J1.
Note: The Debug link connector J8 must be left unconnected so that the Link2 Debug
Probe is left unpowered and does not contend with the SWD interface signals from the
external Debug Probe.
4. Self-test demo application
The LPCXpresso54S018M board is pre-programmed with a spirit level demonstration
and self-test diagnostic program. The spirit level demonstration uses the User LEDs and
on-board accelerometer (as described earlier in this manual). The self-test application is
available for download from the LPCXpresso54S018M board page under the software
and tools tab.
4.1 Self-test application and VCOM driver installation
The self-test application uses the VCOM port for control and to report self-test results.
For Windows 7 or 8 host platforms, the LPC-Link2 serial port driver must be installed
before attempting to use this feature (unless previously installed). If MCUXpresso IDE or
LPCScrypt has been used on the Host system being employed then this driver will
already have been installed; if not then please download and install LPCScrypt from
https://www.nxp.com/LPCScrypt. Note that it is not necessary to install these drivers
when using Window 10, MacOS or Linux.
4.1.1 Serial terminal setup
The self-test application is controlled via a serial link to a host computer. You may either
use the VCOM port or attach a serial to USB cable to header P4 and installing a jumper
on JP6.
When using the VCOM option, after completing any necessary VCOM driver installation,
connect the board to a host computer over USB using connector J8 on the Board. The
Board should enumerate on the host computer as several devices, including a VCOM
device called LPC-LinkII VCOM. Note the port number of this device using your host
computer device manager (see Section 5.3 for more details).
Use a serial terminal emulation program (such as PuTTY or TeraTerm), open a
connection to the VCOM port or USB serial cable and set the baud rate to 115200, 8 bits,
not parity and no flow control.
4.1.2 Running self-tests
When the board powers up or reset, the spirit level demo will run. To enter self test
mode, press the User button (SW5). The spirit level demo will stop running, the test
menu will be displayed on the serial terminal and a prompt to enter the test name will be
displayed, as shown in Fig 4. Type the name of the test you wish to run, then press
enter. Tests will return to the prompt after running in most cases, but some tests require
the User button to be pressed to be terminated. Reset can also be pressed to exit test
mode.

5. Link2 debug features
This section describes the features provided by the on-board Link2 Debug Probe. See
the Getting Started section for more information on how to program the device.
The Link2 Debug Probe is implemented using an LPC432x MCU (circuit reference U21),
which provides a high speed USB port interface to the host computer that runs the
development tools. This device is not intended for developer use and should only be
used with approved firmware images from NXP. The Link2 on-chip flash memory is
factory programmed with a firmware image that supports CMSIS-DAP debug protocol,
but also includes several other USB end point functions:
• Virtual COM (VCOM) port: a serial device that can be used with any host computer
application design for serial port communication (e.g. Teraterm, puTTY, etc.) Set the
terminal program for baud rate to 115200, no parity, 8 bit data, 1 stop bit, no flow
control.
• SWO trace end point: this virtual device is used by MCUXpresso to retrieve SWO
trace data. See the MCUXpresso IDE documentation for more information.
• Power measurement probe: this virtual device is used by MCUXpresso to retrieve
power measurement data from boards that support this feature (e.g. LPCXpresso V3
boards, including the LPCXpresso546x8/540xx.) See Section 9 for more details on
this feature.
• I2S/SPI bridges: bridge device from I2C and SPI ports of the LPC54S018J4M target.
All of these devices are independent of each other and of the CMSIS-DAP debug device
that is enumerated when the board is connected to a host computer; for example, the
VCOM port can be used if the board is running an application when no debugger is
running.
In order to correctly install and use the Link2 device on the LPCXpresso54S018M
(required for any debugging purpose) for Windows host computers, install the drivers
first. These drivers will automatically be installed when MCUXpresso IDE has already
been installed. If these IDEs are not being used, it is recommended LPCScrypt be
installed as this also includes the required drivers. All these tools and utilities are
available for free download at https://ww.nxp.com.
The CMSIS-DAP firmware image installed at the factory (and by LPCScrypt) will uniquely
identify itself to the host computer so that more than one board can be connected to that
host computer at any time. Some toolchains cannot discern between multiple debug
devices; refer to your toolchain documentation for more information (note the
MCUXpresso does support multiple LPCXpresso board targets.) It is recommended that
LPCScrypt be used to update the Debug Probe firmware in order to ensure the latest
version is being used (see Section 5.2.)

Note: The Link2 only boots when the board is power cycled; the reset button on the
board does not reset the Link2.
When using MCUXpresso IDE, the Link2 can be automatically booted with the latest /
most appropriate firmware for that IDE version by installing JP5 before powering up the
board. This is the recommended approach for the MCUXpresso IDE. Note that if JP5 is
installed the VCOM port (and other devices mentioned above) device will not appear until
the IDE boots the Debug Probe. The Debug Probe is booted once a debug session is
started (that is, the IDE attempts to download code to the target).
5.1 What the Link2 boot LED indicates
LED D10 is the Link2 MCU BOOT0_LED indicator. This LED reflects the state of Link2
MCU pin P1_1. When the boot process fails, D1 will toggle at a 1 Hz rate for 60
seconds. After 60 seconds, the Link2 MCU is reset.
5.2 Programming the Link2 firmware
As mentioned earlier in this section, it is not normally necessary to program the Link2
firmware. However, this can easily be accomplished using the supporting utility,
LPCScrypt.
To program the Link2 Flash the Link2 device (LPC432x) must be in DFU mode. If the
Link2 already has a valid image in the flash, it will need to be forced into DFU mode by
placing a jumper on JP5, and power cycling (disconnecting then reconnecting power via
J8.) Link2 MCU programming is performed using the LPCScrypt utility (see
http://www.nxp.com/lpcutilities). After installing the utility, run either of the Program LPC-
Link2 with CMSIS-DAP or Program LPC-Link2 with Segger J-link utilities to program the
firmware, and follow the on-screen instructions. Further instructions for using the tool are
located on the utility web page.
5.3 VCOM port
The identifier of the VCOM port will vary between boards and hosts. To determine the
COM port, open the Windows operating system Device Manager. This can be achieved
by going to the Windows operating system Start menu and typing “Device Manager” in
the search bar. In the device manager look under “Ports”; the LPC-LinkII UCom Port
device and its name should be visible. NOTE: this VCOM port will only appear if (a) the
Debug Probe has been programmed with the CMSIS-DAP firmware and the Debug
Probe DFU link is removed at power up, or (b) if the Debug Probe has been configured
for DFU boot (JP5 installed) at power up and MCUXpresso IDE has booted it (by starting
a debug session.)

Fig 5. Identifying the VCOM port
If the J-Link firmware image has been programmed into the Debug Probe and DFU boot
mode is not being used, then a VCOM device called Jlink CDC UART port will appear
instead of the LPC-LinkII UCom port.
5.4 Configuring the LPCXpresso54S018M to debug an external target
The LPCXpresso54S018M board’s Link2 Debug Probe may be used to debug an offboard target MCU. The on-board Link2 Debug Probe is capable of debugging target
MCU’s with a VDDIO range of 1.6V to 3.6V. To keep the on-board target
LPC54S018J4M MCU from interfering with the SWD interface, JP1 must be fitted. The
Link2 Debug Probe SWD should be connected by a ribbon cable between the P1
connector to the off-board target MCU SWD interface. Power the LPCXpresso54S018M
board from the Link USB connector J8, and fit jumper JP2 across pins 2 - 3 (External
Target).
6. Troubleshooting debug sessions
In some cases, the ability to make a debug connection can be lost due to the LPC54xxx
target running code that does not allow the host debugger system to gain control of it.
Some reasons for this can be:
• Application code causing a hard fault
• Application code disabling the SWD debug port pins
• The boot image has an invalid header
In many cases, the board can be put back in a state where the debugger can gain control
by using the ISP buttons and pressing and releasing the reset button (for example,
holding down ISP0 to force the device into the serial ISP boot mode). If problems persist
with ISP mode entry being required, try mass erasing the flash; this can be done using
the MCUXpresso IDE device programming utility.
LPC54S018JxM devices do not have any pull-ups enabled at reset, and in cases where
an application is using the SDRAM this could cause the EMC_D2 through EMC_D4
signals to be driven by that device (since the P1_12 port of the target could be floating).
Since these signals are shared with the ISP0-2 pins, an undesired ISP boot mode could

be inadvertently selected. In these situations, try removing power for several second,
then hold down ISP0 reconnecting power to the board.
7. Board power connections & measurement
The LPCXpresso54S018M board requires +5V input to power the on-board voltage
regulators which in turn power the Link2 Debug Probe and other +3.3V circuits, the
LPC54S018J4M target and other +1.8V circuits, and the Arduino +5V and +3.3V power
rails. When the main external power source is from the Link2 side USB micro B-type
connector (J8), both the Link side and LPC54S018J4M Target sections of the board are
powered. When the main external power is from the power only USB micro B-type
connector (J1), or one of more of the USB device ports (USB0 at J3 or USB1 at J2), only
the LPC54S018J4M target and supporting devices and peripherals are powered.
7.1 LPCXpresso54S018M current measurement
The LPC54S018J4M current can be measured by measuring the voltage across a sense
resistor in series with the supply, a current meter or using the on board current
measurement circuit. Each of these methods will be described in subsections below.
There is no current monitoring of the Link2 section circuits on the board. The Target side
power going to LEDs and support ICs is not monitored by the current measurement
circuit. The LPC54S018J4M BGA package has the core and IO power both sourced
from the same VDD pins.
When a shield board is attached, attempting to measure the lowest possible power the
LPC54S018J4M IO pins must be configured according to how the software has
configured the shield board to ensure there is no extra current from the LPC54S018J4M
IO ports that have external pull-up or pull-down resistors enabled.
There are several leakage paths through the various devices on the
LPCXpresso54S018M board, so this board may not be suitable for accurately measuring
the lowest possible leakage current achievable in a target application.
7.1.1 LPC54S018J4M Vsense resistor current measurement
The voltage across a pair of 1Ω resistors in series with the target LPC54S018J4M VDD
can be manually measured at JP4 across pins 1 and 4 on the PCB. For a higher range of
current a jumper should be installed between pins 3 and 4 of JP4 to short out on of these
resistors. The voltmeter positive probe is applied to JP4 pin 1 (see silkscreen labelling)
and pin 4. Use Ohm’s law to calculate the current (LPC54S018J4M current = measured
voltage / 2 Ω). As an example, if the measured voltage is 20 mV, then 20e-3 / 2 Ω = 10
mA.
Note: The input current to the MAX9634 used in the on-board current measurement will
be included in the voltage measured across this resistor.
7.1.2 LPC54S018J4M VDD current measurement using a current meter
A current meter may be inserted at JP4 between pins 5 and 6 to measure the
LPC54S018J4M VDD input current. Note that a jumper needs to be installed in the 5-6
position when an ammeter is not present so power can reach the LPC54S018J4M target.

7.1.3 LPC54S018J4M VDD current measurement
The LPCXpresso54S018M board has an on-board current measurement circuit
consisting of a MAX9634T (U18) current monitor chip and a 12-bit ADC (ADC122S021,
U23) with a 12-bit sample at 50k to 200ksps. The on-board MAX9634T current monitor
measures the voltage across the LPC54S018J4M VDD Vsense resistors; either 2 Ω or 1
Ω if JP4 jumper 3-4 is installed. The MAX9634 multiplies the sense voltage by 25 to
provide a voltage range suitable for the ADC to measure. A 2-input analog mux selects
between the LPC54S018J4M current monitor and the output off a MAX9634T current
monitor chip on an expansion board (with compatible current measurement circuit onboard). The current measurement circuit is controlled by the Link2 processor and is not
user programmable. Power measurement utilities to use this feature are available in the
MCUXpresso IDE.
Due to input offset voltage variations in the MAX9634, the current measurement circuit is
not recommended for measuring current below 150 uA. See Fig 6 as a guideline for
measurement error versus measured current.

7.1.4 Shield board current measurement
To use the on-board current measurement circuitry, any expansion board must match the
functionality of the LPCXpresso54S018M. Refer to the board schematics for more
information.
8. Board peripheral connections
8.1 LPC54S018J4M USART ports and VCOM support
The LPCXpresso54S018M board provides access to USART connections from
Flexcomm4 at the expansion connector J13.
On LPCXpresso54S018M boards the USART from Flexcomm0 supports ISP UART
mode booting and is used by default for semi-hosting debug messages. This USART is
connected to a serial port on the Link2 Debug Probe, which provides a bridging function
to USB to a virtual com port (or “VCOM” port) on a host computer connected to the
debug link connector, J8. On revision C boards TXD and RXD from this USART are also
available at header P4, for an external serial connection to be made. When using the P4
connector, JP6 must be installed; note that when JP6 is installed the VCOM port
functionality is disabled.
The factory default CMSIS-DAP Link2 image includes UART bridge functionality (VCOM
support), and this firmware is also available with the LPCScrypt utility, available at
http://www.nxp.com/lpcutilities. The J-Link firmware image available from LPCScrypt
(version 1.9 onwards) or directly from SEGGER also has this feature (also see Section
5.3.)
8.1.1 P3 USART header
The P4 header is designed to be used with an external serial to USB or other 3.3V serial
device. P4 is only present on Revision C (and later) boards. Table 3 shows the pin out
information. below. Note that the connections at P4 are made directly to the
LPC54S018J4M device, so care should be taken to avoid ESD discharge and voltages
outside the ratings of the device I/O pins.

8.2 USB ports
The LPCXpresso54S018M incorporates connectors for the two USB ports of the
LPC54S018J4M device – a full speed (USB0) and a high speed port (USB1). Both of
these USB ports support device and host functionality, but only one can be used as a
host port at any given time. Jumper settings must be set appropriately for host mode
selection, as described in this section.

The MCUXpresso SDK for LPC54S018J4M includes USB stacks for both host and
device, with several supporting application examples.
8.2.1 USB full-speed port (USB0)
The LPC54S018J4M Full Speed (FS) USB port is connected to micro AB USB connector
J3. This section describes functionality support by this board and associated jumper
settings for this board.
8.2.1.1 Device mode
The FS port supports USB device mode operation; no jumper settings are needed to
configure this mode. When using the port in device mode, a standard micro USB cable
can be used.
8.2.1.2 Host mode
The FS port supports USB device mode operation but, due to sharing of some signals
and power supply circuitry, requires the following settings:
• Connect external +5V power via USB connector J1. This is required for the FS USB
port to be able to power the devices connected to it.
• Install JP10
• For each of JP9, JP11, JP12, JP13 install a jumper in position 2-3.
• Use of a micro AB adaptor to connect an external USB device may be required, as
most USB device have either a type A or micro B connector.
Note: The Ethernet and HS USB Host functions are disabled when the board is
configured for FS USB Host operation. Also, note that Expansion connector port PIO4-7
is no longer available when using this mode.
8.2.2 USB High Speed port (USB1)
The LPC54S018J4M High Speed (HS) USB port is connected to micro AB USB
connector J2. This section describes functionality support by this board and associated
jumper settings for this board.
8.2.2.1 Host mode
The HS port supports USB device mode operation but, due to sharing of some signals
and power supply circuitry with the FS port, requires the following settings:
• Connect external +5V power via USB connector J1. This is required for the HS USB
port to be able to power the devices connected to it.
• Ensure JP10 is not installed (default).
• Install a jumper at JP9 in position 1-2 (default).
• Use of a micro AB adaptor to connect an external USB device may be required, as
most USB device have either a type A or micro B connector.
(Note: Although not required for the HS USB port operation, it is recommended to check
JP11, JP12 and JP13 have a jumper in position 1-2 to enable Ethernet operation and
availability of the I/O at the Expansion connector D8.)

functions may be used at once. By default jumper JP6 is open, connection the Flexcomm
3 SPI port to the Link2 device; install JP6 if using the SPI port on J14.
By default, solder jumpers JS15 and JS16 connect the LPC54S018J4M Flexcomm 1 I2C
port to the Link2 device; these may be removed if they will interfere with other devices
interfaced to J14. Note there are 2.2KΩ pull-up resistors to 3.3V for these SDA and SCL
connections.

8.5 Expansion connectors (including Arduino connectivity)
The LPCXpresso54S018M board includes four expansion connectors (J9, J10, J12 and
J13) incorporate an Arduino Uno revision 3 footprint in their inner rows. These
connectors provide access to the CAN interfaces, additional digital microphone support
signals, I2S, I2C, USART, SPI and GPIO/INT/PWM connections. Note that several of the
signals available at these connectors are shared with other connectors or board
functions, so may not be usable if those other functions are being used.

8.6 Ethernet port
The LPC54S018J4M incorporates an on-board 10/100 Mbps Ethernet MAC. The
LPCXpresso54S018M board includes an on-board LAN8720A-CP PHY and RJ45 jack
with integrated link status LEDs.
The MCUXpresso SDK for LPCXpresso54S018M includes drivers, LwIP stack and
several examples to show how the Ethernet function can be used.
Due to sharing of pin functionality on the 180 pin LPC54S018J4M package, on this board
port pins P1_16 and P1_23 must routed via jumpers JP14 and JP15 respectively to
either be used for Ethernet (MDC and MDIO signals) or to EMC address lines A10 and
A11. Place in location 1-2 (EN) when using Ethernet or position 2-3 (SD) when using
EMC.
8.7 Smart Card support
Smart Card 0 interface connections are routed to J10 pins 13 (P0_20) and 15 (P0_21)
via solder jumpers JS38 and JS37. Since these signals are also used for the EMC
(SDRAM) address lines A2 and A3, these solder jumpers are left open by default. If
these solder jumpers are closed, then care should be taken not to access the SDRAM
and thus cause bus contention.

The board includes a Winbond 128Mb SDRAM connected to the 16-bit external memory
interface available on the LPC54S018J4M BGA180 part. The MCUXpresso SDK
includes drivers that have optimized external memory settings for use of this memory.
Due to sharing of pin functionality on the 180 pin LPC54S018J4M package, on this board
port pins P1_16 and P1_23 must routed via jumpers JP14 and JP15 respectively to
either be used for Ethernet (MDC and MDIO signals) or to EMC address lines A10 and
A11. Place in location 1-2 (EN) when using Ethernet or position 2-3 (SD) when using
EMC.

10. Other board features
This section describes board functions not mentioned elsewhere in this document.
10.1 LCD with capacitive touch
The LPCXpresso54S018M has connectors and adhesive pads for a Rocktech LCD to be
added by the user. This LCD panel may be ordered from https://www.nxp.com (use part
number RK043FN02H-CT). When installing the panel it is recommended that an example
program that uses the LCD panel (such as the emWIN examples provided in the SDK) is
used to test the connections before securing the panel in place with the adhesive pads.
Note: The LCD data lines are shared with the PDM0 interface of the LPC54S018J4M
device (the LCD is enabled by default), and solder jumpers may need to be modified to
change between these configurations (see section 10.5 for more details.)
On-board voltage pump circuitry is provided to drive the LCD backlight using an
AP5724WG device. This is enabled using PIO3-31.
The MCUXpresso SDK includes drivers and example applications for the LCD and
capacitive touch controller.
10.2 Audio codec
The LPCXpresso54S018M board incorporates a Cirrus Logic (Wolfson) WM8904 audio
codec, powered via a dedicated regulator. This codec has both I2C (for control) and I2S
(for data) interfaces.
The I2C interface of the codec is routed to Flexcomm 2 of the LPC54S018J4M, the same
connection as used for the other I2C devices on the board; the Codec has an address of
0b0011010.
The Flexcomm 6 and Flexcomm 7 interfaces of the LPC54S018J4M are connected
respectively to the Codec for data sent to / received from the Codec. These I2S
connections from the LPC54S018J4M are also connected to the Expansion connectors
(see Section 8.5 for more information); solder jumpers may be removed to disconnect the
on-board codec if an external I2S device is to be used instead.
The line input to the codec is routed to a 3.5mm stereo jack socket (J5) through the
circuit shown in Fig 7.

via the circuit shown in Fig 8.
Fig 8. Headphone / line output circuitry
The MCUXpresso SDK includes drivers and example code for the audio codec.
10.3 SD card
The full size SD card (J7) includes in the LPCXpresso54S018M board provides a 4-bit
SDIO interface to support memory cards, plug-in WiFi modules, etc. Power enable to the
socket is provided via PIO2-5, with LED D7 providing a visual indication when power is
applied.
The MCUXpresso SDK includes drivers and examples of using this interface with SD
memory cards.

10.4 Accelerometer
The board includes an NXP MMA8652FCR1 accelerometer, interfaced to Flexcomm 2
(ports PIO3-23/PIO3-24) of the LPC54S018J4M. The accelerometer has an I2C address
of 0b0011101.
10.5 Digital Microphone
The LPC54S018J4M device incorporates dual digital microphone interfaces. A low power
Knowles SPH0641LM4H digital microphone is incorporated on the board, interfaced to
the PDM1 microphone interface. Note that the Knowles digital microphone is designed to
be mounted on the underside of a board, with audio passing through a hole in the board.
Note that the PDM0 interface of the LPC54S018J4M is also available for interfacing to an
external microphone via the Expansion connectors, but due to signal sharing with this
function and LCD data lines 14 and 15, solder jumpers JS33 and JS36 need to be moved
to the 2-3 position to enable this function (thus disabling correct LCD operation).
The MCUXpresso SDK includes drivers and demonstration code for capturing data from
the on-board digital microphone and an external microphone of the same type (the latter
requires board modification).
10.6 USER button
This button can be used to generate an interrupt by pulling down the PIO1-1 of the
LPC54S018J4M to ground.
11. Dual CAN transceiver Shield (OM13099)
The OM13099 shield board is a dual CAN/CAN-FD transceiver, available as a
standalone item from NXP and distributors, which has been designed to work with
LPC54xxx series evaluation boards. This board features the NXP TJA1059 dual
transceiver, plus an RS232C transceiver. This section provides a brief overview of the
board and how to use it with the LPC54S018M-EVK.
