AS3953 – AN01 – Demoboard Description
1. General Overview
This application note describes the AS3953 Tag Demo Kit and its usage. The purpose of the
demonstrator is to show all the features and functionalities of the IC. The demo work s with a
reader (Phone or AS3911 GP demonstrator). The main features are:

Demonstration of a file transfer with different datarates

Demonstration of passive EEPROM programming via RF Field which then will be read
out later when the board is connected and powered – demonstrating ISO14443A-4
compliance

File and URL transfer (bidirectional) with an NFC phone – demonstrating framing mode
The Demo Kit allows you to supply all components by the PC USB Port. No external supply or
battery is needed. Except the USB cable and the flex cable (included), no wireing is needed.
This allows a fast and comfortable Demo of the AS3953.

2. Hardware Description
2.1. Demo Board Description
The AS3953 demo kit is comprised of 2 boards, the analog tag board and the controller board.
The analog tags consist of the AS3953 and an coil antenna. There are the option to mount
additional two matching component (one serial and one parallel) on these tags.
Attenation: It is necessary to cut the line between the pads of the serial component foot print, if
a component should be placed here.
The flex cable connector consists of 8 pins:
P1: VSS/GND
P2: /SS (active low)
P3: SCLK
P4: MOSI
P5: MISO
P6: IRQ
P7: VP_SPI
P8: VP_REG
The controller board mainly consists of the USB connector, PIC27FJ64GB002 and a 8MHz
crystal. The board is powered by USB. The above mentioned construct allows:
1. Optional possibility to add another antenna PCB on top
2. a provision to disconnect the on-board micro and connect another micro for the
development purpose
3. havested power measurement with the VP_REG - and GND - pins.


To transmit from AS3911 (Reader) to AS3953(NFiC):
On AS3911 GUI select “load image”, select “speed settings” and click on “Write to Card”
to execute the file transfer. NOTE: do not forget to keep the AS3953 antenna on AS3911
antenna.

To transmit from AS3953(NFiC) to AS3911 (Reader):
On AS3953 GUI select “load Image”. On AS3911 GUI, select “speed settings” and click
on “Read from Card” to execute the file transfer.

EEPROM Read/write (from RF Field):
This can be done passively. Disconnect the analog tag board from the controller board
so that it is not powered. Place it on the top of the AS3911. Use the GUI sub-tab in the
AS3953 tab of AS3911 GUI. Click on “Read EEPROM” and see the config bit changing.
The EERPOM can be written by just changing the values here. NOTE: be aware of the
effects while writing address 3 and 4.


EEPROM Read/write (from MCU):
Now connect this Analog tab board to the controller board and connect it to the GUI via
USB. The EEPROM tab in the AS3953 GUI can be used to read/write out the EEPROM
content when the AS3953 is not in the field.

3.2. Demonstration with AS3953 & NFC phone (Android 4.0 onwards)
The NFC FW in the PIC MCU has been written such that it sends and receives the NDEF
messages. Hence no special app is requried to send a message to a standard NFC phone.
Nevertheless, we have developed an app to send info from phone to the AS3953 GP demo.

Move to Type 4 Tag tab in the AS3953 GUI and install the provided android app on the
NFC phone.

File/URL Transfer from GUI to Phone:
Select an image or URL which needs to be transfered to phone. Selected option should
show up in the right side of the GUI. Now just unlock the phone and place it on the
AS3953 GP demo antenna. Note: The filesize is limited to 64Kbit (limited by NDEF
message framework)


File/URL Transfer from GUI to Phone:
open the amsNFC app and click on “Transfer Image” or “Transfer URL”. Select an image
or URL respectively and place the phone on the AS3953 GP demo antenna. The file
transfer starts automatically.
