NFC Nutshell NFC Modules
General Kit component topology
The Kit consists of different types of modules, which can be connected application specific.
Each module type has a different color.
Fig 1 always insert FFC cable straight
Module interconnection concept
The Nutshell Kit can be operated in different configurations. The connection between the
different modules is done via FFC cables and zero force sockets. The Kit modules can be
connected to a host via different interface modules see deztails in the NFC Nutshell Kit
interface module user manual.
Figure 2 Kit modules interconnection via FFC cables
Fig 3 always insert FFC cable straight
Important Notes:
•Open and close the connector carefully.
•Always insert straight –do not apply force
•Avoid cable/connector misalignment –potential short cut and damage
•If you observe communication issues over time, exchange the FFC cable with a spare
one.
•DO NOT disconnect, bend or move the Kit while modules are powered to avoid short
circuits.

NFC Modules
Fig 4 NFC Module
Different NFC Modules are available to cover most applications. Currently the NFC Nutshell
KIT supports the following NFC ICs:
•CLRC663, CLRC663plus family members
•PN5180
•PN7462 family - t.b.released
•PN512 (for legacy reasons)
•PN7150 - t.b. released (with LPC 11u68 MCU Module and GMMC 7150 firmware
NFC Module hardware topology
The topology of the NFC modules is shown next:
Fig 5 NFC Module interface MCU/HOST interface, power and antenna connection
As can be seen above, the NFC frontends are connected to the MCU via SPI interface. This
allows the user to operate with the maximum performance.
The modules also features the EMC filter which is necessarily close to the output of the NFC
front end.
Note: 3 pin antenna connection is symmetrical with no preferred direction

PC –NFC Direct Communication Mode
Standard Kit configuration
Fig 6 PC –Standard connection Interface - MCU- NFC
Besides using the Kit with an MCU Module connected, there is the possibility to connect the
Modules directly
This mode allows an easy implementation using the PC as direct communication interface.
Fig 7 PC - NFC direct execution
For using the KIT without any MCU the kit has to be connected as shown above. Using the
Protocol Converter Tool, the user has to choose the NFC Direct mode.
This changes the NFC interface to UART and allows easy access to the NFC front end using
the converter module as USB to UART converter.
For further development, the export controlled version of the NXP reader library can be
used. This version features C++ based projects which can be used to communicate with the
front end.
Note: This works only with the export controlled version of the NXP reader library. A valid
NXP Doc store account and access is needed.
More details can be found in the Interface User Manual of the Protocol Converter Module.
