User Manual

I. Introduction:
ASUS NFC-PN544 is a module equipped with both NFC and USB3.0 Hub functions. It
can be connected to Windows based systems by USB3.0 A to A type cable. The
USB3.0 Hub is activated by embedded driver of Intel chipset(PCH) and the NFC is
activated by NXP provided driver(only available on Win8)
II. Design Reference:
ASUS NFC-PN544 is composed as the following:
a) USB3.0 hub IC: This section includes Asmedia ASM1074 chip and its external
components completed refer to the reference design. An addtional EEPROM is
utilized to store the corresponding FW. Note this module only applies bus power
from USB port.
b) NFC IC: This section includes NXP PN544 C3 chip and the external components
completed refer to the reference design. The antenna design is also based on the
refernce design of NXP PN544 demo board(schematic, layout, BOM etc). The
driver provided by NXP is applicable only on Windows 8.
c) USB to UART convertor IC: Exar XR21B1411 is adopted to bridge from USB3.0 Hub
IC to NFC IC, PN544C3 communicates with the connected system by UART
interface. The driver is available on line.
d) 1 A type USB3.0 upstream port connector: the main connection port to a
Windows based system, an A to A type USB3.0 cable is necessary.
e) 2 A type USB3.0 downstream port connectors: for external devices certificated by
USB compliance, and are applicable up to USB3.0.
f) 5 white LEDs: to indicate the power of USB bus is on.
Note: there is no external power design for this module, heavy loading behaviors (ex. 2 USB
removable HDDs data R/W concurrently) on USB devices is not advised.
III. Feature:
Contactless protocols: ISO14443A/B, ISO15693, ISO18092 USB compliance: USB3.0,
USB2.0, USB1.1
