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].

Now the hardware is ready for use. Please connect the LPCXpresso board to the

Blueboard.

Be informed that there is the possibility of arranging the boards vice versa. The pictures

below will illustrate how that is meant.

2.6 Interesting points of measurement

Although the Blueboard is not designed to do extended measurements, there are some

points of measurement one might be interested in.

To give some examples, a few of these points of measurement will be described in the

following.

2.6.1 RXP - receiver input pin for the received RF signal

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

6. Close the bridge at R12

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

6. Close the bridge at R29
