Added Value of Using AS3909/10

Benefits

Features

Close loop adjustment of ASK modulation for accurate control

of modulation depth in case of ISO-14443B protocol

Stable Modulation Index

Enabling Ultra Low Power Applications

No communication holes

Low power (3.5μA) NFC target mode

AM/PM demodulator

Measuring signal strength on RFI pins

Accurate RF envelope measurement (8 bit A/D)

High output power at 3.3V power supply:

• Up to 700mW in case regulator is externally shorted

• Up to 500mW in case differential output and antenna

trimming is used

Enables various antenna configurations

• 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

Increases EMD immunity

(1)

Enable tuning of the Antenna LC Tank

Automatic Antenna tuning (AAT)

For support of other standards and custom

protocols (ISO-15693, FeliCa, ...)

Transparent mode

Enabling Inductive wakeup in combination

with MCU

Amplitude and phase measurement

Supporting 13.56 MHz and 27.12MHz Quartz oscillator with fast

start-up

Supply voltage range from 2.4V to 3.6V

Wide temperature range: -40ºC to 85ºC

32-pin QFN (5x5mm) for AS3910 and 32-pin TQFN (5x5mm) for
