Data Sheet

1 General Description

The AS3910 is a high performance 13.56MHz HF RFID Reader IC.

With austriamicrosystems’ unique antenna management technology

it is optimized for applications with directly driven antennas.

The AS3910 is unequalled in the domain of HF Reader ICs in that it

contains two differential low impedance (1.5

Ω) antenna drivers.

These drivers are unmatched meaning the IC can deliver up to 8

times the output power of a standard HF Reader IC using the same

power supply voltage.

Additionally using this configuration means half of the power

consumption at the same output power.

The IC has an operating voltage down to 2.4V and a low power

operating mode of 5mA. This means the AS3910 is ideal for portable

or battery powered applications.

For applications where high power is required (EMV) the AS3910

can attain up to 1W. This means there is no need for complex

external booster circuitry.

The component count and complexity of the design is further

reduced through the patented automatic modulation depth

adjustment.

The analog front end (AFE) is complimented by a highly integrated

data framing engine for both ISO-14443 A and B.

This includes data rates up to 848kbits with all framing and

synchronization tasks on board. This enables the customer to build a

complete HF RFID Reader using only a low end micro.

The AS3910 not only supports reader to tag communication, but

sports Peer to Peer communication using the NFCIP-1 active

communication mode with a data rate of 106kbps.

The IC has a SPI, which enables bi-directional communication with

the external microcontroller.

Other standard and custom protocols, such as ISO-15693 can be

implemented via transparent mode.

2 Key Features

Close loop adjustment of ASK modulation for accurate control

of modulation depth in case of ISO-14443B protocol

Antenna trimming system providing correction range of LC

Low power operating mode reduces receiver consumption from

10mA to 5mA

Low power (3.5µA) NFC target mode

Integrated regulators to boost system PSRR

AM/PM demodulator to eliminate communication holes

RSSI measurement

Accurate RF envelope measurement (8 bit A/D)

High output power at 3.3V power supply:

- up to 1W in case regulator is externally shorted

- up to 500mW in case differential output and antenna trimming

is used

- up to 125mW in case of single ended output and antenna

trimming is used

Squelch feature which performs gain reduction to compensate

for noise generated by transponder processing

User selectable and automatic gain control

Transparent mode to implement other standard and custom

protocols (ISO-15693, Felica, ….)

Quartz oscillator capable of operating with 13.56MHz or

27.12MHz crystal with fast start-up

Additional A/D converter input, Serial peripheral interface (SPI)

with 32 byte FIFO

Supply voltage range from 2.4V to 3.6V

Wide temperature range: -40ºC to 85ºC

QFN 32 5x5 package

3 Applications

The AS3910 is ideal for applications where the reader antenna is

directly driven (no 50

Ω cable). It also includes several unique

features, which make it especially suitable for low power and battery

powered applications.
