1.0 INTRODUCTION
This document is the System Reference Manual for LPC4330-Xplorer; a cost effective evaluation
platform for NXP’s LPC43xx (dual core Cortex M4 and M0) MCUs. This document reflects its contents
which include system setup, debugging, and software components. This document provides detailed
information on the overall design and usage of the board from a systems perspective.
2.0 LPC4330-Xplorer Overview
2.1 Introduction
The NGX LPC4330-Xplorer is a compact and versatile evaluation platform for the NXP's Cortex-M4
based MCUS. NGX's evaluation platforms are generally not tied up to any particular debugger or
compiler/IDE. However it is not practical to test and ensure that the solution would work out of box with
all the available debuggers and compilers/IDE. As long as the compiler supports the particular MCU and
the debugger supports the standard debug interfaces like the SWD/JTAG you can use this platform with
any tool. For our development we use ULINK and KEIL as the debugger and compiler/IDE respectively.
The board is supported by extensive sample examples allowing you to focus on the application
development.

The board is shipped with two USB cables, one USB device cable and one USB host adapter cable
Unused I/Os brought to a header (pin compatible with Xpresso pinning*)
*The I/0s brought out to the header are not 100%pin compatible with Xpresso Pinning, unlike the Xpresso
boards, this evaluation platform has lot of connectors on board and also the controller has some other
special features like the SGPIO, which have been brought out to the header. We have put in our best
efforts to have maximum number of pins to be Xpresso pin compatible.

3.0 LPC4330-Xplorer verification
NGX's evaluation platforms ship with a factory-programmed test firmware that verifies all the on-board
peripherals. It is highly recommended that you verify the board, before you start programming. Also this
exercise helps you get acclimatized with the board quickly.
To run the tests you will need the following:
LPC4330-Xplorer
Power: USB cable (you can power it through either port, we recommend to use USB1 for the
verification) or external power supply (Alternatively the Xplorer has a 5V in pin available for
powering through external power source)
PC: With Windows7 or XP (32-bit)
One USB AM to Micro B cable in addition to the one provided with the KIT
Micro SD card
2-GB USB pen drive
Audio-in (Auxiliary) cable (3.5mm diameter connector)

3.2 Powering the Board
The LPC4330-Xplorer can be powered through USB; we can either power it from USB0 port or USB1
port. It is highly recommended that the user tests all the peripherals as soon as the board is received. A
regulated supply can be supplied to the 5V pin on the Xplorer-LPC4330 header.
Note: The USB power can source only up to 500 mA of current. For applications having higher current
requirements we recommend to use an external power supply. Please note that the external power supply
is not a part of standard delivery.
3.3 Verifying all the peripherals on LPC4330-Xplorer
The following section focuses on the verification of all the peripherals supported on the LPC4330Xplorer.
The order of the tests is mentioned in the same manner as the flow of the test firmware. We highly
recommend that you follow the order of the test. The test firmware is designed in a manner that the user
needs to spend as minimum time as possible to verify all the on-board peripherals. The test firmware
executable resides on the Quad Flash. The BOOT select switch is configured to execute from the Quad
Flash interface.
Note: The test firmware “Debug Messages” or flow might be changed in due course. Generally these are
only cosmetic changes so that the usage is easier. If you observe a different message than the one
mentioned in the Manual, do not worry and please proceed with the test
Note: To restore the Factory Default for LPC4330 Xplorer Board kindly refer to section 6.0
Important Note: The user needs to press the RESET switch twice to be able to reset the controller. This
is due to the issue with the silicon. Please note that if you power-up the board then it would have been
reset once (power-on reset) and in this case you need to press the RESET switch only once for the
controller to reset. In situations where the Xplorer is powered up and running a firmware and you wish
to reset the controller, one needs to press the RESET switch twice.
Power up the board over USB1 port and we are all set to verify the LPC4330-Xplorer peripherals.
Before we get to the verification we need to install the Virtual COM port drivers needed for the LPC4330-
Xplorer (USB1 port) to appear as a Virtual COM port (Used for viewing the debug messages on serial
emulation tool). Fortunately, this is a one-time setup and fairly simple. On a Windows machine the user
needs to point to the location of the INF file (the INF file can be found in the download folder provided
on product registration; the path for INF file is:
..\Xplorer_release\LPC4330_Xplorer_Examples_V1\LPC4330_Xplrer_UsbVcomLib).

Steps to install the VCOM drivers on Windows 7 machine:
Step 1: Connect USB1 to the computer, Open Device Manager, You can find “NXP LPC18xx VCOM”
new device listed under ‘Other devices’.
Fig.4
Step 2: Next, Right click on the NXP LPC18xx VCOM and then left click on Update Driver Software.

Step 7: The LPC18xx USB VCom driver is successfully installed. Click on close.
Fig.10
Step 8: Now LPC18xx USB VCom Port (COM12) is ready to use.
Fig.11
Note: The Virtual COM is listed under the device manager. Please note that the COM port list under the
Device Manager is automatically updated with the COM port number for the Virtual COM. On our test
machine we see two COM ports listed COM1 and COM12. COM1 is the actual COM port and COM12 is
the virtual COM port. The COM12 will appear only if the Xplorer board is connected (USB1) to the PC.
Every time the Xplorer is reset the user needs to close the Hyper Terminal application and restart it
again.

3.3.1 LEDs
Test setup and verification:
As soon as the Xplorer is turned ON or reset; the test LEDs go ON & OFF for a couple of times, this
simple test validates the LEDs. The Xplorer has one Green LED and one Blue LED. These LEDs are also
connected to the outputs of the SCT lines. Please refer to the schematics for more details.
3.3.2 USB1 (Virtual COM port)
Test setup and verification:
For the very first time the Windows machine will ask for the appropriate Virtual COM drivers to be
installed.
Steps to select USB1 VCOM port on HyperTerminal in Windows 7 machine:
Step 1: Open a HyperTerminal, Enter the name and then click on OK.

Step 2: Select USB1 Vcom Port (COM12) and then click on OK.

Step 3: Click on Restore Defaults and then click on OK.

Step 4: Now the USB1 VCom is ready to use.
Fig.15
Note: You would not be able to proceed with the verification unless the Virtual COM drivers are installed.
The firmware waits for the USB1 to enumerate as VCOM port.

User Manual: LPC4330-Xplorer
Page | 18
3.3.3 User Input Switch
Test setup and verification:
Once the VCOM drivers are installed the Xplorer waits for the User Input Switch to be pressed. Onlyafter
detecting a user button (SW2) press the test firmware proceeds with validating other peripherals. This
synchronization is necessary to ensure that the debug messages on the VCOM port can be viewed from
the start of the test. Without this synchronization the test firmware would proceed with the debug messages
being displayed, while the user is still configuring the Hyper-Terminal or other serial emulation tool.

3.3.4 USB0 (HID device)
Test setup and verification:
Connect the USB cable to USB0 connector. The USB enumeration can be checked in device manager.
The Xplorer enumerates as a Human Interface Device (HID). On a Windows machine this can be
confirmed by looking in to the ‘Device Manager’ under ‘Human Interface Devices’.
Fig.17
Note: The Xplorer is shipped with only one ‘USB AM to micro B’; to test the USB1 interface you would
require another similar cable. In the subsequent firmware releases the firmware would configure the
USB0 port as USB host.

3.3.5 Ethernet
Test setup and verification:
The test firmware configures the Xplorer board as a Webserver.
Fig.18
The Ethernet interface can be verified by either using a PING command in the windows command
prompt.
