1. Introduction
This application note gives a detailed overview of the hardware for working with the
RC663 contactless reader - we use the LPCXpresso LPC 1114/301 and the Blueboard
(Chapter 2)- the installation procedures of the Development Environment (Chapter 4.1)
and the handling of the reader projects using the NXP Reader Library (Chapter 4.2).
Detailed information on the RC663 in connection with the NXP Reader Library can be
obtained at [1]. But with the information provided in this document one will be fine to get
started.
The projects used in this documentation are:
•Communication with MIFARE Ultralight Chapter 5.1
•Communication with MIFARE Classic Chapter 5.2
•Communication with MIFARE DESFire Chapter 5.3
•Polling for Tags in the RF - field Chapter 5.4
•Exemplary Peer to Peer functionality Chapter 5.5
2. Hardware overview of the Demo Reader
The demo reader is made up of 2 separate boards:
•A RC663 demo board (called Blueboard) provided by NXP. This board has
connectors which are designed to exactly fit the ones of the companion, the
LPCXpresso LPC 1114/301 development board.
•A commercial LPCXpresso LPC 1114/301 (12NC: 935290886598, Type:
OM11049+598) development board which can be provided by NXP or bought directly
on the market. See [2] .
Once the two boards are joined via the connectors, the demo reader is ready for use.

antenna. The RC663 supports different kind of contactless communication methods and
protocols at 13.56 MHz:
oReader/Writer mode supporting ISO/IEC14443A/MIFARE,
oReader/Writer mode supporting ISO/IEC14443B,
oReader/Writer mode supporting FeliCa scheme,
oPassive initiator mode according to NFCIP-1
oReader/writer supporting ISO/IEC 15693,
oRefer to the data sheets of this IC [3] for more details
Thanks to the relevant solder bridge, the host link of the RC663 demo board can be
configured for:
oSerial UART,
oI2C,
oSPI
The voltage of the power supply VDD, the pad supply PDD and the transmitter supply
can also be configured independently to 3,3 V or 5 V using the solder bridges.

2.1.1 Derivates of the RC663 demo board (Blueboard)
To meet the interests of the market, we also offer Blueboards with a slightly modified
RC663 on it.
The four versions are as follows:
•RC663 Blueboard
This Blueboard with the RC663 offers the full functionality. It supports the modes
described above. In the following text we always relate to the RC663 Blueboard. If
not, this will be indicated by a note.

•SLRC610 Blueboard
This Blueboard with the RC610 works with ISO/IEC 15693 tags only. To use this
Blueboard, one will have to manually change one parameter in the NXP Reader
Library.
In the folder ../src/NxpRdLib_PublicRelease/intfs/ open the file
“phhalHw_Rc663_Reg.h” and scroll to the line
#define PHHAL_HW_RC663_CMD_LOADPROTOCOL 0x0DU
It should be around line 476.
Change the value from 0x0DU to 0x03U.
Now, one should be able to use the SLRC610 Blueboard.
•MFRC630 Blueboard
This Blueboard with the MFRC630 works with ISO/IEC 14443A cards only. No
modification in the NXP Reader Library is needed.
•MFRC631 Blueboard
This Blueboard with the MFRC631 works with ISO/IEC 14443A and ISO/IEC 14443B
cards only. No modification in the NXP Reader Library is needed.
If one has one of the limited Blueboards, one will have code in some of the example
projects that will not work with the very board. There is no need to adapt the code for the
derivate (except for the one described above). If one for example executes code for
ICODE tags and has a MFRC631 Blueboard, this code will have no effect at all. It will
behave as if there was no tag in the field.
2.2 CE certification of the Blueboard
The current version of the Blueboard (v.3.0) is CE (European Conformity) compliant.
2.3 LPCXpresso LPC1114 development board
To work with the provided projects, one will also need an LPCXpresso LPC development
board. Such a board is not included in the Blueboard hardware package.
The LPC1114 development board integrates an NXP ARM Cortex-M0 microcontroller
LPC1114 with 32 Kbytes of Flash memory and 4 Kbytes of RAM. It integrates a lot of
hardware parts:
o1 Serial UART interface,
o1 SPI controller,
o1 I2C controller,
oSerial Wire test/debug interface,
oFor detailed information, see LPC11xx User Manual [4]
The LPCXpresso board contains a JTAG/ SWD debugger called the “LPC-Link” and a
target MCU. LPC-Link is equipped with a 10-pin JTAG header and it seamlessly
connects to the target via USB (the USB interface and other debug features are provided
by NXP’s ARM9 based LPC3154 MCU).

2.4 Alternative to the LPCXpresso LPC1114
With the provided code one can use the LPCXpresso LPC1115 (12NC: 935297664598,
Type: OM13035+598) instead of the LPCXpresso LPC1114 without the need of any
adaptation in the code. Its advantage is the larger flash memory of 64KB instead of
32KB. That makes the debugging easier because one doesn’t need to have the
optimization turned on to make the code fit into the flash. For instructions on how to port
the project to work with the LPC1115 see the description in chapter 7.7.
As an alternative, one can also use the LPCXpresso LPC1227 (12NC: 935294603598,
Type: OM13008+598) but needs to use the ported projects that are provided on the
product web site of the CLEV663B. For more information please see chapter 7.8
2.5 Preparation of the hardware
The first step after unpacking the Blue Board and the LPCXpresso is soldering the
connectors onto the boards in order to join them later. In our example we use a multipoint
connector as one can see on the pictures below.
Fig 4. Multipoint Connectors we used
One may buy these connectors at any electronic store. Here are some examples [5].

2.7 Preparing the Blueboard for the use with SPI or I2C
The Blueboard is generally delivered in I2C configuration, for this reason one only needs
to change the configuration if the use of the board in SPI configuration is desired.
From Blueboard version 3.0 on the layout slightly changed. So we provide two different
descriptions for changing the interface from I²C to SPI.
2.7.1 Blueboard version 2.1 and below
There are exactly six solder bridges to change.
1. Open the bridge at R18
2. Open the bridge at R15
3. Open the bridge at R11
4. Close the bridge at R17
5. Close the bridge at R14

See the picture of the Blueboard in SPI configuration below.
Fig 13. Blueboard in SPI configuration
To use the Blueboard in SPI configuration with the provided software projects, one has to
execute two small adaptations in the code, which are described in section 7.5.
2.7.2 Blueboard version 3.0 and above
These boards are delivered in SPI configuration. To change that to I²C, one needs to
change six solder bridges.
1. Open the bridge at R15
2. Open the bridge at R21
3. Open the bridge at R26
4. Close the bridge at R16
5. Close the bridge at R20

3. Installation of the LPCXpresso Board
The guidelines to install the reader are as follows:
•Connect the LPCXpresso Board to a real USB2.0 port of the PC (for speed
reasons) using the mini-USB connector. The PC detects and installs the Board
automatically.
•Once the Board is installed, open the Device Manager of the PC to check that
the installation has been successful. The item “USB Device with DFU
Capabilities” is being displayed.
Please be sure to always connect both USB ports to the computer. If the USB port of the
Blueboard is not connected to a USB port, it won’t work because of the missing power.

4.3 Start the project
One can quickly start the reader project by editing the main function in the module
main.c. This function first performs the hardware initializations of the LPC1114/301 and
the RF transceiver RC663.
Detailed descriptions of the code in the form of comments have been provided in the
main.c file. This should provide a detailed overview of how to initialize certain
components and get data out of and onto the card in the RF field.
Remember: If one is using the SLRC610 Blueboard, the code needs to get edited as
described in 2.1.1 before one can run the code.
4.3.1 Run the project
Before running the project, please ensure that the LPCXpresso with the Blueboard is
connected to the computer.
Although the project names include the string LPC1115, they are preconfigured for the
use with the LPCXpresso LPC1114.
Please ensure that the used LPCXpresso LPC1114 board has the label LPC1114/301 on
its processor. If it has the label LPC1114/302, you need to change the MCU type in the
LPCXpresso IDE setting. Please refer to chapter 7.7 for the steps.
If one is using the projects with the Silica Tusa Board instead of the RC663
Blueboard, please find the needed modifications in the code at section 0.
