and target modes, up to 424 kbit/s

– Low level modes to implement MIFARE

Classic® compliant or other custom

protocols

 Key features

– Dynamic power output (DPO) controls the

field strength to stay within given limits

– Active wave shaping (AWS) reduces over-

and under-shoots

– Noise suppression receiver (NSR) allows

reception in noisy environment

– Automatic antenna tuning (AAT) via

variable capacitor

– Integrated EMVCo™ 3.0 compliant EMD

handling

– Automatic gain control and squelch feature

to maximize SNR

– Low power capacitive and inductive card

detection

– Low power NFC active and passive target

modes

– Adjustable ASK modulation depth, from 5

to 40%

– Integrated regulators to boost system

PSRR

– AM/PM and I/Q demodulator with

baseband channel summation or automatic

channel selection

– Possibility to drive two independent single

ended antennas

– Measurement of antenna voltage amplitude

and phase, RSSI, on-chip supply and

regulated voltages

 External communication interfaces

– 512-byte FIFO

– Serial peripheral interface (SPI) up to

10 Mbit/s

– I2C with up to 400 kbit/s in Fast-mode,

1 Mbit/s in Fast-mode Plus, and 3.4 Mbit/s

in High-speed mode

 Electrical characteristics

– Wide supply voltage and ambient

temperature range (2.6 to 5.5 V from -40 °C

to +105 °C, 2.4 to 5.5 V from -20 °C to

+105 °C)

– Wide peripheral communication supply

range, from 1.65 to 5.5 V
