XRAI NFC MOUDULE
USER MANUAL & SPECIFICATION
USER MANUAL
I. Introduction
XRAI is one kind of NFC module that could be embedded in one IT system by simply connecting the
module to his target microcontroller and start developing his application software.
Note that this module is also used for the NXP PN544/PN65O standard Evaluation Kit software.
It is recommended that this user guide be read in conjunction with the XRAI datasheet.
II. DESIGNREFERENCE
As illustrated in Figure 1 below, the XRAI reference design module consists of the following:
‧ Reference Design: This section includes the NXP PN544C3 chip but also all the external
components in an optimized BOM and form factor. When the user wishes to incorporate the XRAI to
PCB, it is strongly recommended that this reference design (i.e. schematics, placement, layout, BOM,
etc...) is copied “as is” in the final application board to guarantee optimum performance, regulatory
compliance and lowest development time and design effort.
Figure 1: Overview (Top View)
‧ MCU FPC/FFC Connector: Enables the user to connect the XRAI control and interface pins to the
host microcontroller (please refer to the XRAI datasheet for further information).
‧ IPEX Connector: Provided for COXIAL Cable or antenna connection.
‧ Hardware Block Diagram: Connection rule: user could refer the block diagram in Figure 2
