General Description
The AS3953A NFC interface IC (NFiC) delivers low cost, ultra low
power NFC Forum functionality to multiple different
applications. The AS3953A is a analog front-end with integrated
14443A data framing and SPI interface. It is designed to create
a fast data link between an ISO 14443A reader device (PCD) and
a microcontroller. The AS3953A is
passively powered
meaning
that it can be supplied from the PCD magnetic field, eliminating
the need of a continual external supply. This makes the
AS3953A perfect for wireless communication to a low-power
battery powered device.
The AS3953A is used with an appropriate antenna coil
connected to the terminals LC1 and LC2, and behaves as a
normal passive ISO 144443A tag (PICC). After the anti-collision
protocol is passed, the PCD sends a
Wake-Up
command, which
wakes up the microcontroller by sending an interrupt. From this
point onwards, the AS3953A serves as a data link between the
microcontroller and the PCD. AS3953A can also operate as
NFCIP-1 target at 106 kbit/s.
The AS3953A includes an onboard EEPROM that can be
accessed either from the PCD or from the microcontroller via
the SPI interface. This built-in flexibility makes it ideal for two
types of applications:
Where personalization data is programmed by the PCD
(even in case the SPI side is not powered) and it is later
read by microcontroller through SPI interface.
Where log data is stored periodically by the
microcontroller and can then be read by the PCD even
when the microcontroller is not powered.
A regulated power supply voltage extracted from the PCD field
is also available on a pin and can be used as power supply for
external circuitry. For example, an external microcontroller and
a sensor could be powered from the PCD field combined with
pass through data rates up to 848kbit/s, which means the
AS3953A is ideal for contactless passive programming of MCU
systems. The AS3953A can also operate as a stand-alone ISO
14443A tag.
The AS3953A supports ISO 14443A up to Level-4, meaning a
contactless smart card or an NFC forum compatible tag (Tag
Type 4) can be built. Having a NFC Forum compatible tag
interface allows the AS3953A to be used in an application where
a standard NFC enabled phone is used as a PCD.
